The preparation technology of the lithium ion battery is simple, cost is low, and large-scale production can be achieved easily.

Description

technical field [0001] The invention relates to the fields of new energy materials and electrochemical technology, in particular to a lithium ion battery. Background technique [0002] The power battery is the heart of new energy electric vehicles and the key to the development of the new energy electric vehicle industry. However, the energy density, safety performance, and rate performance of lithium-ion batteries, which have been widely used in mobile electronic products, still cannot meet the needs of people in electric vehicles. The requirements for the use of automobiles have become a bottleneck hindering the large-scale promotion of electric vehicles. Lithium-ion batteries are composed of positive and negative electrode materials, separators and electrolytes. The electrode material is the core part of the battery and determines the electrochemical lithium storage performance of the battery. Therefore, the performance of the negative electrode material directly affects ...
