Definitions
- the present invention relates to a nonaqueous electrolyte battery module provided with a flexible exterior material.
- Non-aqueous electrolyte batteries represented by lithium ion secondary batteries are widely used as power sources for portable devices such as mobile phones and notebook personal computers because of their high energy density.
- non-aqueous electrolyte batteries have begun to be used as power sources other than portable devices.
