Abstract:
The invention provides a battery electrode capable of improving a lifespan characteristic (cycle characteristic at the time of high temperature endurance). The battery electrode has a collector and an active material layer formed on a surface of the collector. The active material layer includes a plurality of binders having different specific gravities. The binders are more present at the collector side of the active material layer.
