Abstract
Disclosed is a battery pack that enables its outer case to be formed in small thickness regardless of formability and material property, and has enhanced twisting resistance. The battery pack includes a bare cell for generating electricity, a circuit member provided at an upper part of the bare cell and electrically coupled to the bare cell, a frame case formed so as to expose front and back parts of the bare cell externally while covering the bare cell including the circuit member, and a film sheet connected to the frame case so as to cover the front and back parts of the bare cell.
Claims13
A battery pack comprising:
- a bare cell for generating electricity;
- a circuit member provided at an upper part of the bare cell and electrically coupled to the bare cell;
- a frame case covering the bare cell and the circuit member, a front surface of the frame case having a front opening, a front part of the bare cell being exposed through the front opening of the frame case;
- and
- a first film sheet having two surfaces and four edges coupled to the frame case and covering the front part of the bare cell, the first film sheet being separated from the bare cell with a space formed between the first film sheet and the bare cell, said space preventing contact of the first film sheet with the bare cell throughout an entire one of the surfaces and all four of the edges of the first film sheet with the exception of a welding projection.
