Title:
POLYMERIC ELECTROLYTE FOR SECONDARY BATTERY AND LITHIUM SECONDARY BATTERY COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2019/009594
Kind Code:
A1
Abstract:
The present invention relates to a polymeric electrolyte for a secondary battery and a lithium secondary battery comprising the same. More specifically, the present invention relates to a polymeric electrolyte for a secondary battery, which comprises a polymer and an electron acceptor having at least one double bond as a dopant, such that mechanical properties, ionic conductivity, and electrical conductivity are improved; and a lithium secondary battery comprising the same, which has enhanced electrochemical stability under high temperature and high voltage.
