Abstract
A current collector includes an organic substrate layer and conductive layers disposed on two surfaces of the organic substrate layer. An initial melting temperature and phase change latent heat of a material of the organic substrate layer of the current collector are controlled so that the current collector can absorb a large amount of heat after reaching the initial melting temperature.
