Abstract
Official abstract text for this publication.
The present invention is directed to a composition containing a block copolymer, a metal ion and a specific oligomer which increases ion conductivity without decreasing mechanical strength of the composition. The composition is useful for a solid polymer electrolyte of a secondary battery.
First claim
Opening claim text (preview).
1 . A composition comprising a) a block copolymer comprising i) a polymer block having a final melting temperature greater than 60° C. or a glass transition temperature greater than 60° C., and ii) a polymer block including a polyalkoxide; b) a metal ion; and c) 0.1 to 40 weight percent of an oligomer based on the block copolymer, the oligomer comprises ethylene oxide and propylene oxide in the structure, the weight average molecular weight of the oligomer is less than 1,000. 2 . The composition of claim 1 , wherein the oligomer further comprises an amino group. 3 . The composition of claim 1 , wherein the polyalkoxide of the polymer block of the block copolymer comprises ethylene oxide and propylene oxide. 4 . The composition of claim 1 , wherein the metal ion is lithium ion. 5 . The composition of claim 1 , wherein the composition further comprises carbonates. 6 . A solid polymer electrolyte comprising the composition of claims 1 . 7 . A secondary battery comprising the solid polymer electrolyte of claim 6 .
