Description

technical field

[0001] The following description relates to a battery module including a plurality of unit cells coupled by connection members. Background technique

[0002] The battery module is a module including a plurality of unit cells connected in series to realize high power and large capacity. The rechargeable battery module is used as a power source of equipment requiring a large capacity, such as an electric motor for driving an electric vehicle or a hybrid vehicle. The unit battery may be a rechargeable battery capable of being recharged. Recently, high-power rechargeable batteries using non-aqueous electrolytes having high energy density have been developed.

[0003] A positive terminal and a negative terminal protrude from each unit cell, and a plurality of unit cells are alternately arranged such that positions of the positive terminal and the negative terminal are opposed to each other. The battery module includes connection members so that the unit cells a...
