Title:
METHOD OF MANUFACTURING A LITHIUM-ION SECONDARY BATTERY ELECTRODE SHEET BASED ON AN ACTIVE MATERIAL DRY POWDER
Document Type and Number:
WIPO Patent Application WO/2016/006197
Kind Code:
A1
Abstract:
In a method of manufacturing a lithium-ion secondary battery electrode sheet proposed herein, a current collector (11), a powder material (13) of granulated particles, and a binder solution (12) are prepared. The binder solution (12) is applied onto the current collector (11). Subsequently, the powder material (13) of the granulated particles is fed onto the current collector (11). Then, the powder material (13) of the granulated particles is pressed against the current collector (11). In the basic manufacturing method, adhesive strength of the powder material (13) of the granulated particles is enhanced after the powder material (13) of the granulated particles is fed onto the current collector (11) and before or while the powder material (13) of the granulated particles is pressed against the current collector (11).
