Title:
NEGATIVE ELECTRODE FOR NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY AND NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY
Document Type and Number:
WIPO Patent Application WO/2020/189452
Kind Code:
A1
Abstract:
This negative electrode for a non-aqueous electrolyte secondary battery comprises a negative electrode mixture that contains: a negative electrode active material capable of electrochemically storing and releasing lithium ions; a negative electrode additive agent; and an acrylic resin. The negative electrode active material contains a silicon-containing material. The negative electrode additive agent contains at least a silicon dioxide and a group 2 element oxide, and the group 2 element oxide includes at least one selected from the group consisting of BeO, MgO, CaO, SrO, BaO, and RaO. The acrylic resin contains at least a unit of (meth)acrylate. The content of the group 2 element oxide in the negative electrode additive agent is less than 20 mass% with respect to the total amount of the negative electrode additive agent.
