Abstract: An electrode for a battery includes a thin plate current collector and an active material layer coated on the current collector. The current collector is provided at a top surface with a coated current collector part and an uncoated current collector part adjacent to the coated current collector part. The uncoated current collector part has less yield stress than the coated current collector part.
