Abstract:
A secondary battery electrode which suppresses decrease in capacity and lithium deposition at low temperatures is provided. An electrode for a secondary battery includes an electrode active material layer containing a polymer having a cationic group, an anion corresponding to the cationic group, and an electrode active material, and the cation density in the polymer is 0.1 to 15 meq/g.
