LIQUID ABSORBING SHEET AND NONAQUEOUS ELECTROLYTE BATTERY PACK

摘要

A liquid absorbing sheet comprising a liquid absorbing resin layer having excellent liquid absorption properties to a nonaqueous electrolytic solution of a constituent nonaqueous electrolyte secondary battery of a nonaqueous electrolyte battery pack (particularly, a lithium-ion nonaqueous electrolyte secondary battery pack) is disclosed. The liquid absorbing resin layer is formed by applying, to a supporting base, a monomer composition containing a monofunctional monomer component (A) containing a monofunctional monomer (a) which can form a homopolymer that is soluble to the nonaqueous solvent of the nonaqueous electrolyte secondary battery and a multifunctional monomer component (B), and irradiating the thus-obtained coating film with ultraviolet light, thereby causing polymerization.
