Abstract
Description
technical field
[0001] The invention relates to a positive electrode material, a preparation method thereof and a lithium ion battery. Background technique
[0002] It has been less than 20 years since the birth of lithium-ion batteries, and its application field has rapidly expanded from the initial mobile communication to various portable electronic products involving people's life and entertainment, military, aerospace, medical treatment, communication, etc. It is developing into large and medium-sized energy storage equipment and power supply. The great commercial success of lithium-ion batteries and the promotion of the development of the above fields are unmatched by any secondary battery.
[0003] At present, the most researched and used lithium-ion battery cathode materials are mainly lithium transition metal oxides, including hexagonal layered structure materials (typically such as LiCoO 2 、LiNi 0.5 mn 0.5 o 2 and LiNi 1 / 3 co 1 / 3 mn 1 / 3 o 2 ), LiMn with sp...
