Abstract: A battery comprises a battery housing and an electrode which is accommodated in the battery housing. Outer faces of the battery housing substantially form the shape of a hollow body which has an accommodation space for accommodating at least a substantial portion of a device which is to be supplied with power by the battery. An outer casing surface of the battery housing can therefore form a portion of a housing of the device. Since the battery housing protects both the active portion of the battery enclosed therein and the components of the device accommodated in the accommodation space of the battery, and a separate device housing and battery housing can therefore be largely avoided, there is a resultant saving in weight and volume. The freedom of design for devices which are provided with batteries is also increased.

Abstract: A battery (1) comprises a battery housing (2) and an electrode which is accommodated in the battery housing. Outer faces of the battery housing (2) substantially form the shape of a hollow body which has an accommodation space (3) for accommodating at least a substantial portion of a device (100) which is to be supplied with power by the battery. An outer casing surface of the battery housing (2) can therefore form a portion of a housing of the device (100). Since the battery housing (2) protects both the active portion of the battery (1) enclosed therein and the components of the device (100) accommodated in the accommodation space (3) of the battery (1), and a separate device housing and battery housing can therefore be largely avoided, there is a resultant saving in weight and volume. The freedom of design for devices which are provided with batteries is also increased.
