Battery and battery pack

Abstract

A battery is provided that includes a laminate film having a metal layer and a thermal adhesive resin layer, a battery element which is covered with the laminate film, and leads which are connected to the battery element. The leads are sandwiched between opposing thermal adhesive resin layers, and extend outside the laminate film. The thermal adhesive resin layer has thermal adhesive resin and fine resin fibers.

Description

Batteries and Battery Packs technical field The present invention relates to batteries and batteries. Specifically, the present invention relates to a laminated film battery and battery pack employing metal layers and resin layers. Background technique In recent years, as mobile information terminals such as mobile phones / notebook PCs and PDAs (Personal Data Assistants) have rapidly progressed in size and weight reduction, high-capacity batteries are increasingly required as a driving source. Non-aqueous electrolyte secondary batteries represented by lithium-ion secondary batteries have high energy density and high capacity, so non-aqueous electrolyte secondary batteries are widely used as driving sources for mobile information terminals, driving sources for power tools, and in-vehicle drive source. As electronic devices decrease in size and weight, there is a need to reduce the size and weight of electronic components used in the electronic devices. Therefore, a nonaq...
