How to distinguish between positive and negative materials for lithium batteries?

Lithium battery cathode material manganese dioxide is an important component, used for chemical reactions of charge and discharge, and the addition of components is to improve the performance of the battery. Lithium battery negative material metal lithium or its alloy metal is the negative electrode material, these things are coated on the copper foil, the negative electrode occurs. The cathode material has always been the core of lithium batteries, and its choice directly determines the level of battery performance. The choice of positive electrode material is important, the reversible lithium removal and lithium intercalation transition metal oxide is one of the important components of lithium batteries. The commonly used anode materials for lithium batteries include lithium manganese oxide, lithium cobalt oxide, lithium iron phosphate, and ternary materials. The commonly used anode materials include carbon materials and silicon-based materials. Among the lithium battery materials, the negative electrode material is an important component and can have a greater impact on the overall battery performance. At present, negative electrode materials are divided into two categories, one is carbon materials for commercial use, such as natural graphite, soft carbon, etc., and the other is in the state of research and development, but the future direction is a great non-carbon negative electrode material. For example, silicon-based materials, alloy materials, tin-gold materials, and so on. As far as each lithium battery material is concerned, the degree of profitability improvement is not the same. Regarding lithium batteries, the commonly used positive current collector is aluminum foil, and the negative current collector is copper foil. In order to ensure the internal stability of the current collector in the battery, the purity of both is required to be above 98%.
