Abstract
Proposed is a heat-shielding sheet for a battery, the sheet sequentially including an inner layer made of a polymer resin, a silicone foam layer, a graphite layer, and a glass bubble layer. Thus, there are advantages of solving the disadvantage of polyurethane foam, used in existing heat-shielding sheets for batteries, that in the event of a fire, the fire spreads and thermal runaway is accelerated, being lighter than metallic materials, and being capable of rapidly preventing flames and heat from spreading.
Claims9
A heat-shielding sheet for a battery, the sheet comprising:
- a silicon foam layer;
- and
- a functional layer laminated on either or both surfaces of the silicone foam layer, the functional layer comprising one or more layers selected from a flame-retardant layer, a graphite layer, and a barrier layer.
