Abstract
Description
technical field
[0001] The invention relates to the technical field of manufacturing lithium battery devices and lithium battery materials, in particular to a method for improving the electrical performance of a negative electrode copper foil collector of a lithium battery. Background technique
[0002] Lithium battery anode materials hold the lifeblood of power battery safety. In lithium ion battery anode materials, except graphitized mesocarbon microspheres (MCMB), amorphous carbon, silicon or tin occupy a small market share, natural graphite and artificial Graphite occupies more than 90% of the market share of anode materials. Graphitized carbon materials, amorphous carbon materials, nitrides, silicon-based materials, tin-based materials, new alloys and other materials.
[0003] Lithium-ion batteries are mainly composed of positive electrodes, negative electrodes, separators and electrolytes. When charging, the potential applied to the two poles of the battery forces th...
