Abstract

The invention relates to the technical field of lithium batteries, in particular to a method for preparing a positive electrode of a metal oxide. According to the method for preparing the positive electrode of the metal oxide, sputter coating of multiple target materials can be carried out at the same time, a film with different atomic component ratios can be obtained according to the sputtering speeds of various target materials, and the target materials can be directly replaced when the positive electrode film, containing different components, of the metal oxide needs to be obtained throughsputtering, so that the process is simple and fast, the production efficiency is high and the massive production requirements are met.

Description

【Technical field】 [0001] The invention relates to the technical field of lithium batteries, in particular to a method for preparing a metal oxide positive electrode. 【Background technique】 [0002] Since the commercial application of ion batteries, its main cathode materials include: LiCoO2, LiNiO2, LiMn2O4, LiFePO4, etc. With the development of science and technology, electronic equipment and electric vehicles have put forward higher requirements for lithium batteries, and the disadvantages of low voltage and small capacity of this type of positive electrode materials have become increasingly prominent. In a new generation of cathode materials, high voltage and high theoretical capacity metal oxide Li β m x N y Q z o α has received widespread attention. This type of cathode material has a higher discharge voltage platform and higher theoretical capacity, so it is expected to be promoted in the fields of consumer electronics, power tools and electric vehicles in the fu...
