A thermal storage device for batteries is provided. In some examples, the thermal storage device is provided for a battery pack that includes one or more rechargeable battery cells. In some examples, the lithium ion battery cells are used. The thermal storage device is in thermal contact with the battery cell. The thermal storage device is made of a material that absorbs heat that is given off by battery cells during discharge. In some examples, the thermal storage device is made of a plastic material. The material has a relatively low thermal conductivity but a relatively high specific heat capacity, allowing heat energy to be stored in the thermal storage device. The thermal storage device prevents the battery pack from overheating during use. The thermal storage device defines one or more cell receiving volumes. In some examples, an axially extending relief volume is provided.

A battery includes an electrode layer, a counter electrode layer, which is a counter electrode for the electrode layer, and a solid electrolyte layer between the electrode layer and the counter electrode layer. The solid electrolyte layer has a first region containing a first solid electrolyte material and a second region containing a second solid electrolyte material. The first region is positioned within a region where the electrode layer and the counter electrode layer face each other. The second region is positioned on an outer peripheral side of the region where the electrode layer and the counter electrode layer face each other, and is in contact with the first region. The first region includes a first projecting portion that projects outward from a region where the electrode layer and the counter electrode layer face each other, and the second region covers the first projecting portion.
