Abstract
Description
technical field
[0001] The invention relates to the technical field of lithium batteries, in particular to a lithium battery cathode material. Background technique
[0002] With the wide application and rapid development of lithium batteries, people have higher and higher performance requirements for lithium-ion batteries, which not only require lithium batteries to have a higher capacity, but also require better capacity retention during repeated charging and discharging. rate, exhibits good cycle performance, and has a long service life. The main constituent materials of lithium batteries include electrolyte, isolation materials, positive and negative electrode materials, etc. The positive electrode material occupies a large proportion (the mass ratio of positive and negative electrode materials is 3: 1 ~ 4: 1), because the performance of the positive electrode material directly affects the performance of the lithium-ion battery, and its cost also directly determines the ...
