Problems solved by technology

However, in the laminated battery in JP-A-2001-256938, it is difficult to install the laminated battery in a curved manner in a limited space due to the limitation of the half-shell shape of the case
In addition, in the laminated battery in JP-A-2003-162989, since resin is filled between the supporting member and the single battery, a prescribed space is required between the supporting member and the single battery, so it is not suitable for a laminated battery that can be mounted. Space creates constraints and it is difficult to install laminated batteries in different shapes

Abstract

An accumulator structure includes a module having a plurality of flat accumulators flatly disposed in a common plane, and the flat accumulators are electrically connected with each other via electrode terminals. Strip-shaped reinforcement members are attached alternately at a front surface side and a back surface side of the module between the electrode terminals. Thereby, a reinforcement and insulation between the electrode terminals can effectively be carried out while a flat structure of the accumulator structure is maintained and bending flexibility is secured, and the accumulator structure can be adjusted to a third-dimensional installment shape.

Description

[0001] This application claims foreign priority based on Japanese Patent Application No. JP-2004-081569 filed on March 19, 2004, the contents of which are incorporated herein by reference. technical field [0001] The present invention relates to battery structures in which a plurality of flat batteries are laid flat in a common plane and electrically connected to each other. Background technique [0002] In recent years, secondary batteries, including rechargeable batteries such as lithium ion batteries, and electrolytic capacitors such as electric double layer capacitors, have become increasingly more compact and lightweight, and have higher energy density. These storage batteries have been actively used as power sources for portable information communication equipment, electric vehicles, or hybrid electric vehicles. [0003] In particular, a laminated battery includes: an outer case made of a laminate obtained by coating a metal layer with resin on both sides; shap...
