Title:
PRODUCTION METHOD FOR LITHIUM-ION BATTERY MEMBER
Document Type and Number:
WIPO Patent Application WO/2020/196591
Kind Code:
A1
Abstract:
The present invention relates to a production method for a lithium-ion battery member obtained by forming an electrode composition layer, which contains electrode active material particles and an electrolyte solution, on a collector or on a separator, said production method comprising a step for forming the electrode composition layer on a surface of a supporter which is different from the collector and the separator, and a step for transferring the electrode composition layer from the surface of the supporter onto the collector or onto the separator, and in the step for forming the electrode composition layer on the surface of the supporter and the step for transferring the electrode composition layer onto the collector or onto the separator, the proportion by weight of the electrolyte solution contained in the electrode composition layer is no more than 10 wt% based on the weight of the electrode composition layer.
