ABSTRACT:
A battery pack having a plurality of battery cells (10) connected in series and/or parallel. The battery pack is provided with a plurality of battery cells (10), each encased in a rectangular external case, and a plurality of separators (20) with electrical and heat insulating properties covering the outside of each battery cell external case excluding electrode terminals (12). Each separator (20) is disposed so as to intervene between adjacent battery cells (10) putting the external cases of those battery cells (10) in contact with both sides of the separator (20). With the external case of each battery cell (10) covered by separators (20) while exposing electrode terminals (12), the electrode terminals (12) are connected together. As a result, excluding required regions, the battery cells (10) can be enclosed and unintended events such as short circuits can be effectively prevented.
