Problems solved by technology

[0005] However, battery packs are required to have a compact structure and durability, but it is not easy to achieve both miniaturization and durability
For example, if the structure of the battery pack is simplified in order to achieve miniaturization, there is a problem of reduced durability
In addition, if a protective structure is provided to improve durability, it will be difficult to reduce the size of the battery pack.

Embodiment Construction

[0066] Hereinafter, the present invention will be described based on preferred embodiments.

[0067] [battery exterior body]

[0068] figure 1 It is a cross-sectional view schematically showing a battery pack 10 as an example of a battery pack using the battery exterior body 1 of the embodiment. figure 2 It is a cross-sectional view schematically showing the battery exterior body 1 .

[0069] The battery pack 10 has a battery exterior body 1 and a plurality of single cells 2 .

[0070] The battery exterior body 1 has a plurality of conductor sheets 3 . figure 1 and figure 2 The illustrated battery exterior body 1 has, for example, four conductor sheets 3 arranged in an overlapping direction. These four conductor sheets 3 are called first to fourth conductor sheets 31 , 32 , 33 , and 34 in order from top to bottom, respectively.

[0071] like figure 2 As shown, the conductor sheets 3 ( 31 , 32 , 33 , 34 ) are laminates formed by laminating the metal layer 6 and the re...

Description

Technical field [0001] The present invention relates to a battery exterior body, a battery pack, and a battery device. [0002] This application is based on Japanese Patent Application No. 2016-134112 (filing date: July 6, 2016), Japanese Patent Application No. 2016-134113 (filing date: July 6, 2016) and Japanese Patent Application No. 2016-134114 (filing date: July 6, 2016) Date: July 6, 2016) claims priority and the contents are quoted here. Background technique [0003] In recent years, as environmental awareness has increased, secondary batteries such as storage batteries and lithium-ion batteries have attracted attention as storage batteries for storing electric energy. For example, in storage batteries for electric vehicles and the like, in order to increase the capacity, a battery pack composed of a plurality of single cells connected is used. Specifically, the battery pack has a structure in which a plurality of single cells placed in a container are connected to e...
