ELECTRODE AND BATTERY CONFIGURED BY USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a battery that can suppress occurrence of cracks in an active material layer and dropout of active material from the active material layer while sufficiently maintaining ion conductivity of the active material layer.SOLUTION: An electrode which is configured to contain a collector and an active material layer containing active material and polymer further has fibrous material in the active material layer and/or on the active material layer, and the fibrous material has an average fiber diameter of 1 μm or more.SELECTED DRAWING: None
