| titleOfInvention | Method for preparing lithium battery cathode additive and preparing cathode by calcining mixture |
| abstract | The invention discloses a method for preparing a lithium battery cathode additive and preparing a cathode by calcining a mixture, which comprises the following steps: selecting several of dimethyl silicone oil, trimethylsilanol and silicon powder with particle size of 1-500 μm as raw materials. The material was weighed and ground in a mortar to a uniform paste, which was then placed in a crucible. Calcining the mixture for 1 to 3 hours in a muffle furnace at 500 to 800 ℃. And uniformly grinding the calcined substance to obtain a sample as an additive. After the additive prepared by the invention is added into graphite, compared with the prior art, the discharge specific capacity of the battery is improved by about 30 percent, and the additive has better cycling stability. |
