Title:
NEGATIVE ELECTRODE FOR LITHIUM SECONDARY CELL, METHOD FOR MANUFACTURING SAME, AND LITHIUM SECONDARY CELL
Document Type and Number:
WIPO Patent Application WO/2013/080775
Kind Code:
A1
Abstract:
The present invention improves the charge-discharge cycle characteristics for a lithium secondary cell. The negative electrode (11) of a lithium secondary cell (1) is provided with a negative-electrode collector (11a), a negative-electrode active-substance layer (11b), and a negative-electrode conductive layer (11c). The negative-electrode active-substance layer (11b) is distributed on the negative-electrode collector (11a). The negative-electrode active-substance layer (11b) has negative-electrode active-substance particles. The negative-electrode active-substance particles include silicon and/or a silicon alloy. The negative-electrode conductive layer (11c) is distributed on the negative-electrode active-substance layer (11b). The negative-electrode conductive layer (11c) includes polyimid resin and/or polyamide acid resin, and graphite particles.
