▎ 摘 要
NOVELTY - An electrode pole piece preparing method involves weighing 90-95% active material, 2-5% physically peeling graphene and 2-5% binder, ready for use under the active material is obtained by mixing graphite and lithium titanate in a mass ratio of 4-9: 1, weighing physically peeling graphene for acidification treatment, after acidification treatment, immersing an active material and the physically peeling graphene in an organic solvent to obtain a mixture, and spray-drying the mixture to obtain a mixed powder, mixing the mixed powder with the binder, and grinding for 0.5-1 hour, adding water and continuously grinding to a uniform viscous state to obtain a slurry, uniformly coating the slurry in a copper foil, drying and removing water from the electrode sheet to obtain the finished product. USE - Method for preparing electrode pole piece for use in lithium ion battery cathode (claimed). ADVANTAGE - The method enables preparing electrode pole piece with better battery cathode rate performance, in simple and easy manner. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for an electrode pole piece prepared by the method.
