Battery

Abstract

The present disclosure provides a battery. The battery includes a case, and bare cells located therein. Each bare cell includes a first electrode, a second electrode and a separator. The first electrode includes a first empty-foil area and a first coating area, each first coating area is divided into two independent parts by one first empty-foil area. The separator is sandwiched between adjacent first electrode and second electrode such that short circuit between the first electrode and the second electrode is prevented. At least two adjacent first electrodes are laminated and welded together at the first empty-foil areas. Two second electrodes are located between two adjacent first electrodes and disposed at both sides of the first empty-foil areas separately. The battery of the present disclosure effectively improves the energy density thereof.
