电解知识

电解科技名词定义中文名称：电解英文名称：electrolysis定义：在电解槽中，直流电通过电极和电解质，在两者接触的界面上发生电化学反应，以制备所需产品的过程。

应用学科：电力（一级学科）；配电与用电（二级学科）电解通电前，Cu2+和Cl－在水里自由地移动着；通电后，这些自由移动着的离子，在电场作用下，改作定向移动。

溶液中带正电的Cu2+向阴极移动，带负电的氯离子向阳极移动。

在阴极，铜离子获得电子而还原成铜原子覆盖在阴极上；在阳极，氯离子失去电子而被氧化成氯原子，并两两结合成氯分子，从阳极放出。

阴极：Cu2++2e－=Cu阳极：2Cl－－2e－= Cl2↑电解CuCl2溶液的化学反应方程式：CuCl2=Cu+Cl2↑(电解）编辑本段电解质概念英文：Electrolyte电解质是指在水溶液中或熔融状态下能够导电的化合物。

例如酸、碱和盐等。

凡在上述情况下不能导电的化合物叫非电解质，例如蔗糖、酒精等。

（单质，混合物不管在水溶液中或熔融状态下能够导电与否，都不是电解质。

）电解质水溶液电解反应的综合分析在上面叙述氯化铜电解的过程中，没有提到溶液里的H+和OH－，其实H+和OH－虽少，但的确是存在的，只是他们没有参加电极反应。

也就是说在氯化铜溶液中，除Cu2+和Cl－外，还有H+和OH－，电解时，移向阴极的离子有Cu2+和H+，因为在这样的实验条件下Cu2+比H+容易得到电子，所以Cu2+在阴极上得到电子析出金属铜。

移向阳极的离子有OH－和Cl－，因为在这样的实验条件下，Cl－比OH－更容易失去电子，所以Cl－在阳极上失去电子，生成氯气。

说明①阳离子得到电子或阴离子失去电子而使离子所带电荷数目降低的过程又叫做放电。

②用石墨、金、铂等还原性很弱的材料制做的电极叫做惰性电极，理由是它们在一般的通电条件下不发生化学反应。

用铁、锌、铜、银等还原性较强的材料制做的电极又叫做活性电极，它们做电解池的阳极时，先于其他物质发生氧化反应。

电化学体系英文

电化学体系英文An electrochemical system is a system that involves the transfer of electrons between an electrode and an electrolyte. This transfer of electrons results in chemical reactions taking place at the electrode surface. Electrochemical systems are widely used in various applications such as energy storage, corrosion protection, sensors, and electroplating.In an electrochemical system, there are two main components: the electrode and the electrolyte. The electrode is the solid conductor where the electrontransfer takes place, while the electrolyte is the medium through which ions can move to maintain charge neutralityin the system.There are different types of electrochemical systems, including galvanic cells, electrolytic cells, and fuel cells. Galvanic cells, also known as voltaic cells, are devices that convert chemical energy into electrical energy through spontaneous redox reactions. Electrolytic cells, on the other hand, use electrical energy to drive non-spontaneous redox reactions. Fuel cells are electrochemicalcells that convert chemical energy from a fuel intoelectrical energy.The performance of an electrochemical system is often characterized by parameters such as the open-circuit voltage, short-circuit current, and power density. These parameters are influenced by factors such as the electrode material, electrolyte composition, and operating conditions.One key application of electrochemical systems is in energy storage, where batteries and supercapacitors play a crucial role. Batteries store energy in chemical form and can be recharged multiple times, making them ideal for portable electronics and electric vehicles. Supercapacitors, on the other hand, store energy electrostatically and can deliver high power outputs, making them suitable for applications requiring rapid energy release.Electrochemical systems are also used for corrosion protection, where sacrificial anodes are employed toprotect metal structures from corroding. By connecting a more reactive metal to the metal structure to be protected, the sacrificial anode corrodes instead of the protected metal, thus extending the lifespan of the structure.In addition to energy storage and corrosion protection, electrochemical systems are used in sensors for detecting various analytes such as glucose, pH, and heavy metals. By utilizing the specific redox reactions of the analyte of interest, electrochemical sensors can provide rapid and sensitive detection in a wide range of applications.Overall, electrochemical systems play a vital role in modern technology and have a wide range of applications in various fields. By understanding the principles of electron transfer and redox reactions, researchers and engineers can continue to develop innovative electrochemical systems for future advancements.电化学体系是涉及电极和电解质之间电子转移的系统。

电学英语知识点总结初中

电学英语知识点总结初中1. What is Electricity?Electricity is the flow of electric charge through a conductor. It is caused by the movement of electrons, which are negatively charged particles, through a material such as a wire. This movement of electrons can be harnessed to create electric currents, which can be used to power devices and perform work.2. Current, Voltage, and ResistanceCurrent, voltage, and resistance are the three fundamental properties of electric circuits. Current is the rate at which electric charge flows through a conductor, measured in amperes (A). Voltage is the difference in electric potential between two points in a circuit, measured in volts (V). Resistance is the opposition to the flow of electric current, measured in ohms (Ω). These t hree properties are related by Ohm's law, which states that the current flowing through a conductor is directly proportional to the voltage across it and inversely proportional to the resistance.3. Electric CircuitsAn electric circuit is a closed loop through which electric current can flow. It consists of a source of electrical energy (such as a battery or generator), a load (such as a light bulb or motor), and conductors connecting the two. There are two basic types of electric circuits: series circuits, in which the components are connected in a single path, and parallel circuits, in which the components are connected in multiple paths. Understanding how electric circuits work is essential for designing and troubleshooting electrical systems.4. Electric PowerElectric power is the rate at which electric energy is transferred by an electric circuit. It is measured in watts (W) and is calculated using the formula P = VI, where P is power, V is voltage, and I is current. Power is an important concept in electrical engineering, as it determines the performance of electrical devices and the cost of electricity consumption.5. Magnetism and ElectromagnetismMagnetism is the force exerted by magnets, which can attract or repel other magnetic materials. It is caused by the alignment of the magnetic dipoles in a material and plays a crucial role in the operation of electric motors, generators, and other electrical devices. Electromagnetism is the interaction of electric currents with magnetic fields and is the basis for the operation of transformers, inductors, and other electrical components.6. Capacitance and InductanceCapacitance is the ability of a component to store electric charge, while inductance is the ability to store magnetic energy. These properties are essential in the design of electroniccircuits and devices, as they determine how electric fields and magnetic fields interact with components. Understanding capacitance and inductance is crucial for designing efficient and reliable electrical systems.7. Electrical SafetyElectrical safety is a critical consideration when working with electricity. It is important to follow proper procedures and use the right equipment to prevent electrical hazards and accidents. This includes wearing protective gear, properly insulating and grounding electrical circuits, and following safety standards and regulations.In conclusion, electricity is a fascinating and essential field of study with a wide range of practical applications. Understanding the key concepts in electrical theory and their practical applications is crucial for anyone working in the field of electrical engineering or technology. By applying this knowledge, we can design and maintain efficient and reliable electrical systems that power the modern world.。

电化学方法与原理英文

电化学方法与原理英文Electrochemical Methods and PrinciplesElectrochemistry is a fundamental branch of chemistry that deals with the relationship between electrical and chemical phenomena. It encompasses the study of various processes, such as the generation of electricity from chemical reactions, the use of electrical energy to drive chemical transformations, and the behavior of materials in electrochemical systems. Electrochemical methods have a wide range of applications, from energy production and storage to corrosion protection and analytical techniques.One of the core principles of electrochemistry is the understanding of oxidation and reduction reactions, also known as redox reactions. In these reactions, electrons are transferred between chemical species, resulting in changes in their oxidation states. The driving force behind these electron transfers is the difference in the ability of the participating species to attract and release electrons, known as their reduction potential. By harnessing and controlling these redox processes, electrochemists can design and optimize various electrochemical devices and processes.Electrochemical cells are the fundamental building blocks of electrochemical systems. These cells consist of two electrodes, an anode and a cathode, immersed in an electrolyte solution. The anode is where oxidation occurs, and the cathode is where reduction takes place. The electrolyte provides the necessary ionic conduction between the two electrodes, allowing the flow of ions and the completion of the overall electrochemical reaction.One of the most widely recognized applications of electrochemistry is energy conversion and storage. Electrochemical cells, such as batteries and fuel cells, convert the chemical energy stored in fuels or reactants directly into electrical energy. Batteries, for example, use the principle of redox reactions to generate a flow of electrons, which can then be used to power various electronic devices. Fuel cells, on the other hand, generate electricity by combining fuel (such as hydrogen) and an oxidant (such as oxygen) in an electrochemical reaction.In addition to energy applications, electrochemical methods are also used in a variety of analytical techniques. Electroanalytical methods, such as potentiometry, voltammetry, and electrochemical sensors, utilize the principles of electrochemistry to detect and quantify the presence of specific chemical species in a sample. These techniques are widely used in fields like environmental monitoring, healthcare, and chemical analysis.Corrosion is another area where electrochemistry plays a crucial role. Corrosion is an electrochemical process that involves the deterioration of materials, usually metals, due to their interaction with the surrounding environment. Understanding the electrochemical principles underlying corrosion enables the development of effective strategies for corrosion prevention and mitigation, such as the use of protective coatings, cathodic protection, and the selection of corrosion-resistant materials.Electrochemistry also finds applications in the synthesis and processing of materials. Electrochemical techniques, such as electroplating and electrodeposition, are used to deposit thin filmsor coatings of various materials onto a substrate. These processes are employed in the production of electronic components, decorative finishes, and protective coatings.The field of electrochemistry is constantly evolving, with new developments and applications emerging as our understanding of the underlying principles expands. Researchers continue to explore innovative electrochemical technologies, such as energy storage systems, fuel cells, and electrochemical sensors, to address pressing global challenges related to energy, the environment, and healthcare.In conclusion, electrochemical methods and principles arefundamental to a wide range of scientific and technological fields. From energy conversion and storage to analytical techniques and material processing, the principles of electrochemistry underpin numerous important processes that shape our modern society. As we continue to push the boundaries of scientific knowledge, the importance of electrochemistry will only grow, making it a crucial area of study for scientists and engineers alike.。

2. Types of EESSs and their working principlesThe working mechanism of any EESS relies on an inherent potential diﬀerence between two electrodes known as the operating voltage. The operating voltage of the device is dictated by the diﬀerences in redox potential of the positive and negative electrode. The potential diﬀerence is used to drive electrochemical reactions on either electrode when they are connected through an external circuit. This creates a flow of electrons from the negative electrode to the positive electrode. The flow of electrons induces oxidation reactions on the negative electrode (anode) and reduction reactions on the positive electrode (cathode) when discharging. The charged electrodes are balanced by a concomitant flow of counter-ions. EESSs are grouped into a number of diﬀerent categories depending on the composition of the electrodes, the counter-ions, and the nature of the redox reactions (Fig. 1).2.1 Solid electrode batteries2.1.1 Metal-ion battery working principle. Batteries operate with a constant voltage defined, approximately, by the potential diﬀerence between the anode and cathode. Because of this, In a galvanostatic charge/discharge experiment the potential of the electrode or device ideally remains constant until the active material has been fully reduced (oxidized). In a cyclic voltammogram experiment, one observes a reversible, sharp redox peak when a redox event occurs (inset Fig. 1a–c).Metal-ion batteries are the most common type of EESSs. They are typically composed of an anode (negative electrode), a cathode (positive electrode), electrolyte (either aqueous, organic, solid-state,18or polymeric10,19), a separator (to prevent short circuiting), current collectors (to collect charge at each electrode), and a cell casing (to keep the components together and prevent exposure to the external environment). Metal-ion batteries are used for a wide variety of both portable and stationary applications for either primary or back-up power. In metal-ion batteries the charged anodes and cathodes are balanced by the metal ion in a ‘rocking-chair’ type mechanism (Fig. 1a). This is a strict requirement imposed by the definition of metal-ion batteries that should be clearly distinct from dual-ion batteries described below. Metal-ion batteries can be constructed with relatively small amounts of electrolyte because the ions balancing the charge at one electrode are constantly being replenished. Additionally, metal-ion batteries are very attractive candidates for use with solid-state electrolytes because the mobility of only one ion needs to be considered.2.1.2 Dual-ion battery working principle.In a dual-ion battery the charged anodes and cathodes are balanced by cations and anions respectively (Fig. 1b). Dual-ion batteries encompass a wide variety of electrolytes and electrodes. The anodes range from negative charge-accepting compounds to reduced metals and inorganic materials. The cathodes can also be a wide variety of materials as long as they are balanced by anions when charged. We will adhere to this definition throughout this review, but we note that others have referred to these systems as organic batteries, metal organic batteries, and radical polymer batteries.14,22Although these terms may be used to describe the electrodes, the convention of naming solid electrode batteries based on the mobile counter-ions is upheld with this nomenclature.2.1.3 Performance metrics of solid electrode batteries.A number of performance metrics need to be considered for the development of electrodematerials for solid electrode batteries. These performance metrics can be used to estimate the overall performance of the device (Tables 1–7). The theoretical capacitance (C theor) of a material is the maximum amount of charge a material can hold with respect to its mass. It is typically reported in m A h gÀ1and is calculated using eqn (1):Here, n is the maximum number of charges the compound can accept (or give up), F is Faraday’s constant, and M is the molecular weight of the compound in g molÀ1. Typically, the C theo r is used to assess how well the material could perform under optimized conditions. If the C theor is reached, then it is expected that the electrode cannot accept any more charge.The specific capacity (C sp) is the measured capacity of the electrode at a specific current density for either charging or discharging. The C sp is reported in m A h gÀ1and by measuring C sp at diﬀerent rates (usually reported as a C-rate, where 1C is the amount of current it would take to collect the total charge of the C theor in 1 hour) the rate capabilities of the electrode can be determined. The C sp is typically calculated from galvanostatic charge/discharge curves using eqn (2):Here, i is the current in milliamperes, t is the time of discharging (charging) in seconds, and m is the mass of the active material in grams. If the C sp at low and high rates are similar, it can be said that the electrode has high rate capabilities. This typically depends on the electron transfer kinetics of the compound, and the electronic and ionic conductivity of the electrode and electrolyte.The coulombic eﬃciency (CE) is measured by dividing the C sp for discharging by the C sp for charging. This provides insight into the reversibility of the redox reactions and indicates whether any side reactions occur with the electrode and electrolyte. The CE is a good indicator of whether a stable solid electrolyte interface (SEI)is formed in the charging cycles and if the material itself will be stable upon extended cycling. If the CE is low in the first charging cycles but increases to B100% afterwards, it is typically attributed to SEI formation.The cycling stability is an important parameter that quantifies the retention of capacity upon charging and discharging the electrode multiple times. Usually this measurement is performed under galvanostatic conditions and is reported as a percentage of the initial capacity after a specified number of cycles. The current density (or C-rate) must be specified for these measurements because the rate can h ave a significant eﬀect on the cycling stability. This eﬀect is especially pronounced if capacity fading is due to electrode dissolution, which is a common problem with organic electrode materials.The potential at which the redox process(es) occur(s) is also a very important parameter. Combined with the capacity, the redox potential can be used to predict the energy density of the device when paired with an anode/cathode of known redox potential. To have a high energy density, the potential of cathode material should be as high as possible while that of anode material should be as low as possible within the electro-chemical window of the electrolyte, or within the electrolytes’ ability to form a stable SEI. Although an ideal battery maintains a constantvoltage while it discharges, real batteries tend to have a decreased voltage with decreasing state-of-charge (SOC).This creates a sloping voltage plateau that is especially apparent in polymeric electrodes or in electrodes with multiple redoxevents.23The reduction and oxidation peak splitting is also important to provide insight into electron-transfer kinetics, and to predict the energy eﬃciency of the device.While energy and power density are important parameters to gauge the performance of energy storage, we chose to exclude them from our evaluation of solid organic electrode materials since they pertain to fully assembled devices and relate to the combined performance of all aspects of the device including both the anode and cathode, the electrolyte, membrane, and resistances associated with various aspects of the device. Additionally, it is important to report the electrode formulations and procedure for electrode manufacturing, electrode morphologies, electrode thicknesses, electrolyte, and the conditions under which the experiments are being performed. All of these factors can have an enormous eﬀect on device performance. For example, in our lab we have observed that changes in the electrolyte solvent can influence the electrochemical properties, such as the capacity, by as much as an order of magnitude. Therefore, we encourage others to report the details of electrode preparation and testing in full.。
