Document Type and Number:
WIPO Patent Application WO/2023/157391
Kind Code:
A1
Abstract:
The present invention provides an outer package material for all-solid-state secondary batteries, the outer package material using a resin which has a melting point that is not as high as those of PET and PPS, while having a high bonding strength after thermal fusion bonding at around 130°C. The above are achieved by an outer package material for all-solid-state secondary batteries, wherein a base material layer, a barrier layer which is formed of a metal or a compound containing a metal, and a thermal fusion bonding layer which has a thickness of 10 µm to 500 µm and contains a polyvinylidene fluoride are sequentially stacked in this order.
