Effects of Conductive Agents and Binders on Compression and Compactability of NCM Powders In the field of energy development, lithium-ion batteries have gradually become an important component of power sources (medical equipment, entertainment equipment, computers, communication equipment, electric vehicles, spacecraft, etc.) due to their advantages of low cost, environmental friendliness, high specific energy, light weight, and no memory effect. Lithium-ion battery positive electrode active materials often use transition metal oxides, such as layered lithium cobalt oxide, lithium nickel oxide, lithium nickel cobalt oxide, or lithium iron phosphate, and negative electrodes often use graphite, silicon-based materials, etc. as active materials. During the development and production process of lithium-ion batteries, it was found that the conductivity of the positive and negative active material particles cannot meet the requirements of the electron migration rate. Therefore, conductive a...

Research progress on pre-lithiation types of silicon-based anodes and compatible binders Pre-lithiation of silicon-based anode Preface With the development of society and the advancement of science and technology, energy consumption is increasing day by day, environmental pollution is also becoming increasingly serious, and has seriously threatened the future survival of mankind. Therefore, it is urgent to develop clean and environmentally friendly renewable energy. However, most renewable energy sources such as wind energy and solar energy are unstable and intermittent, while batteries can directly convert chemical energy into electrical energy, which is not only stable but also has high energy conversion efficiency, which can effectively alleviate the energy pressure we are facing now. Among them, lithium-ion batteries have been rapidly developed due to their advantages such as high energy density, long cycle life, and environmental friendliness, and are widely used in the fields of ...
