Wei:IntroductionCompared with general materials, nano-energy storage materials have shown superior performance: In order to accelerate the healthy development of nano-energy storage, an emerging industry, Standardizing the performance testing methods of nano-energy storage materials has become an urgent task in the industry: In this regard, the International Electrotechnical Commission Electrotechnical Products and The System Nanotechnology Committee (IEC /TC113) has released eight standardized documents on performance testing of nano energy storage materials: According to the needs of domestic industry development, it is planned to adopt relevant standards: GB/T 41232 "Nano-manufacturing key control characteristics nano-energy storage" is the guide The method standard for testing the physical and chemical properties of nano energy storage materials is proposed to be composed of eight parts: --- Part 1: Electrochemical performance test of nano-cathode materials two-electrode battery method: The purpose is to establish the use of two-electrode batteries Relevant regulations for testing the electrochemical performance of nanoscale cathode materials: --- Part 2: Density test of nano cathode materials: The purpose is to establish relevant regulations for testing the density of nanoscale cathode materials: --- Part 3: Testing of nanomaterial contact resistivity and coating resistivity: The purpose is to establish the measurement of nano-electrode material contact Relevant regulations on resistivity and coating resistivity: --- Part 4: Needle punching method for thermal performance testing of nanomaterials: The purpose is to establish a method for testing the thermal properties of nano energy storage devices by acupuncture method: Regulations on the level of out-of-control: --- Part 5: Electrochemical performance test of nano-cathode materials three-electrode battery method: The purpose is to establish the use of three-electrode batteries Relevant regulations for testing the electrochemical performance of nanoscale cathode materials: --- Part 6: Determination of carbon content in nanometer electrode materials Infrared absorption method: The purpose is to establish the infrared spectroscopic absorption method Relevant regulations for determining the carbon content of nano-electrode materials: --- Part 7: Determination of magnetic impurities in nano-cathode materials ICP-OES method: The purpose is to establish the use of inductively coupled plasma Relevant regulations for the determination of magnetic impurities in nanoscale cathode materials by daughter emission spectrometer (ICP-OES): --- Part 8: Determination of moisture content in nano-electrode materials Karl Fischer method: The purpose is to establish the adoption of Karl Fischer Relevant regulations for the determination of moisture content in nano-electrode materials by coulometric titration: The use of future renewable energy technologies, such as electric vehicles, will mainly rely on efficient energy storage systems: Current lithium-ion batteries, super Supercapacitors and their derivative concept systems are considered to be the most promising options for innovation: High energy density and long cycle life are two very important characteristics of electrode materials: Since many electrochemically active materials, such as gold Metal oxides have low electron transport and insufficient electrical conductivity, so composites containing carbon nanomaterials are used to optimize the current flow in battery electrodes: The movement of electrons in the composite will affect the electrochemical reaction and energy density of the battery: In addition, the contact between the electrode material and the metal current collector Electronic contact resistivity is of great significance for achieving low ohmic internal resistance of batteries or capacitors: This document provides a method for measuring the coating resistivity and contact resistivity of nanometer electrode materials, which is used to evaluate the carbon-containing coating: Whether the combination of the composite material composition and the preparation process of the nano-layer nano energy storage electrode is optimal: This method can be used between different research groups Comparison of results: This document is mainly used for the comparison of contact resistivity and coating resistivity of carbon-containing nanocomposites in the research stage, not for the final product Evaluation of middle electrodes: This method is suitable for nano energy storage materials that can only show certain functions and performances by applying nanotechnology: Addition to active materials can quantify or significantly increase the current flow of electrodes in electrical energy storage devices: Since small amounts of nanomaterials are often sufficient to significantly improve High material performance, so the percentage of nanomaterials in the device discussed in this document is not directly related to the application of this document: The nanomaterial content of electrodes, electrode coatings, separators or electrolytes is not relevant for the use of this method: Nanofabrication key control features nanoscale energy storage Part 3: Nanomaterial Contact Resistivity and Coatings Resistivity Test1 ScopeThis document describes a method for testing the contact resistivity and coating resistivity of nanoelectrode materials: This document is intended for use in evaluating the utility of coated composites and in selecting combinations of coated composites and preparation techniques suitable for their application Way:2 Normative referencesThe contents of the following documents constitute the essential

those in lithium-ion batteries or supercapacitors Material: Note: The electrodes applied to lithium-ion batteries or supercapacitors are composed of solvents and A binder is used to form a coating slurry: These slurries are applied to thin metal current collectors by a doctor blade coating process, dried and calendered to form the ultimate after the electrode: The electrodes exhibit a multilayer structure consisting of an aluminum or copper current collector and a coating of electrode material: The electrode material coating contains the active phase [positive electrode - containing Mixed oxides or phosphates of lithium, such as lithium cobalt oxide (LCO), lithium nickel cobalt aluminate (NCA), nickel cobalt aluminum manganate (NCM) and lithium iron phosphate (LFP), negative electrodes such as Graphite and supercapacity activated carbon], conductive phase (such as carbon black, carbon nanotubes or carbon fibers and other carbon nanomaterials) and organic binders [such as polyvinylidene fluoride (PVDF) or styrene-butadiene rubber (SBR)]: 3:1:2 Coating resistivity coatingresistivity The resistance of current flow through the electrode material coating: Note 1: Coating resistivity is also expressed as resistivity: NOTE 2: The electrode material coating resistivity depends on several factors such as raw material, coating process and final electrode preparation technique: The carbon content of nanomaterials is different, The resistivity can be strongly affected by the preparation process and by the density or porosity of the coating: Resistivity can be assessed by preparing a thin coating of electrode material on an insulating substrate: Coating resistivity was tested by four-probe method: Appendix A shows an example of sample design on a 5cm2 ceramic substrate: ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 41232.3-2023_English be delivered?Answer: Upon your order, we will start to translate
