- Example 4 In the electricity storage device structure used in Comparative Example 1, a PP resin container assuming a casing container was a 100% methyl methacrylate polymer container (inner diameter: 98 mm wide ⁇ 148 mm long ⁇ 48 mm deep, resin thickness 2 mm, Change to a container with an open top with five holes of 10 mm diameter on the side of 98 mm (container with holes drilled on the opposite side of the PP resin container assuming a container for an electricity storage device)). Wire the battery so that it can be overcharged, replace the PP resin plate with a thickness of 4 mm with a 100% methyl methacrylate polymer plate and cover it with heat-resistant tape around the edge of the cover.
- the electric storage device structure was obtained by sealing the battery so that there were no gaps, and ejecting substances from the battery due to overcharging only through the five holes.
