PACKAGING MATERIAL FOR BATTERY HAVING HEAT DISSIPATION PROPERTY

摘要

The present invention relates to a packaging material for a battery including a deposited body consisting of an outermost layer, a barrier layer, and an innermost layer, wherein a heat dissipation layer consisting of a carbon material or a mixture of a carbon material and a resin is formed to afford a slip property, flame resistance, printability, and the like as well as a heat dissipation property to the packaging material. The present invention also relates to a packaging material for a battery having a heat dissipation function, containing a carbon material in at least one layer of the above layers.

主权项

1. A pouch-type packaging material for a battery, comprising a heat resistant resin outermost layer, a barrier layer containing aluminum or an aluminum alloy, and a thermoplastic resin innermost layer,
wherein the packaging material for a battery comprises a heat dissipation layer that is prepared by adding a carbon material to at least one constitutional layer selected from the group consisting of an outermost layer, a barrier layer, and an innermost layer, or a separate heat dissipation layer containing a carbon material and a binder resin.
