Abstract
To provide an electrode mixture that suppresses gelling of an electrode mixture slurry and maintains a high binding capacity between an electrode active material and a current collector even after an extended period of time has elapsed since an electrode mixture slurry was produced. The electrode mixture includes: a binder composition—containing a first copolymer of vinylidene fluoride and a polar group-containing compound; and a second copolymer of vinylidene fluoride and chlorotrifluoroethylene—; and an electrode active material of lithium oxide having a pH of water when extracted with water of not less than 10.5.
