Abstract
En 中文
A method of conventional chemical reaction to prepare delithiated cathode materials of Li-ion battery has been introduced. The cathode material of Li-ion battery was mixed with oxidizing agent Na2S2O8 in water, and the liquid was stirred continuously to make the chemical reaction proceed sufficiently, then the reaction product was filtered, finally the insoluble delithiated cathode material was obtained. A series of tests were conducted to verify the composition, crystal structure and electrochemical property of the delithiated cathode materials were all desirable. This method overcomes the shortcomings of battery charging preparation and chemical extraction preparation employing other oxidizing agents.
