In order to accelerate the healthy development of the emerging industry of nano energy storage, With the rapid development of the industry, standardizing the performance test methods of nano energy storage materials has become an urgent task for the industry. The System Nanotechnology Committee (IEC /TC 113) has published 8 standardized documents on the performance testing of nano energy storage materials. In order to meet the needs of domestic industrial development, it is planned to adopt relevant standards. GB/T 41232 "Key Control Characteristics of Nanomanufacturing Nano Energy Storage" is The standard guiding the testing methods of the physical and chemical properties of nano energy storage materials is planned to consist of 8 parts. Part 1.Electrochemical performance test of nano cathode materials Two-electrode battery method.

Nano energy storage technology has been widely used in portable electronic devices, electric vehicles and energy storage systems. The development of nano energy storage devices has put forward higher requirements on the performance. The main performance of energy storage devices depends on the electrode materials. The carbon content of nano-electrode materials is an important control indicator, which will affect the performance and quality of electrode materials. The carbon content is necessary to improve the electronic conductivity between particles. On the one hand, when the carbon content is insufficient, the conductivity If the problem is not effectively improved, the battery will have high internal resistance, low discharge platform or small capacity, which will reduce its rate performance and cycle life. On the other hand, excessive carbon content will cause the carbon to aggregate and become difficult to disperse, which will affect subsequent processing because excess carbon will reduce the activity of the active substances. The proportion affects the energy density of the battery. Since the nano-electrode material has a small particle size and low apparent density, the sample can be easily blown away by the gas in the furnace during the test. This document provides a special sample preparation method, powder tableting, which not only affects the determination of carbon content, but also may contaminate the test system. A method for determining the carbon content of nanoelectrode materials used in electrical energy storage devices to evaluate the optimal formulation of nanoelectrode composite materials This method allows the comparison of results from different research teams. This method is only suitable for comparing the carbon content in nano-electrode materials in the research stage, and is not suitable for evaluating electrode materials in end products. This method is applicable to materials that can only display functions or properties through nanotechnology, and they can be intentionally added to active materials to show Improve the performance of electrical energy storage devices.
