Abstract
A battery includes a cell including a core and a sealing film enclosing the core. The core includes a negative electrode plate, a metal plate, a separator, and a positive electrode plate arranged successively. The battery further includes a protection circuit coupled to the negative electrode plate and one of the metal plate or the positive electrode plate to measure a reference voltage between the negative electrode plate and the one of the metal plate or the positive electrode plate.
