A binder for a battery including polymethyl methacrylate particles and a binder polymer is disclosed. Additionally, a binder composition, and an anode and a lithium battery which include the binder are also disclosed.

Binder for battery, and anode and lithium battery including the same

A binder for a battery including polyurethane particles and a binder polymer is disclosed. Additionally, a binder composition, and an anode and a lithium battery which include the binder are also disclosed.

Disclosed are a binder composition for a rechargeable lithium battery including a cross-linked compound of polyacrylic acid substituted with an alkali cation and polyvinyl alcohol and an electrode and rechargeable lithium battery including the same. The cross-linked compound of polyacrylic acid and polyvinyl alcohol is obtained by heating polyacrylic acid and polyvinyl alcohol to effect a cross-linking reaction via esterification. The cross-linked compound of polyvinyl alcohol and polyacrylic acid substituted with an alkali cation may improve phase stability of a binder, and has high cross-linking ratio, thereby providing for excellent performance of a rechargeable lithium battery.
