| titleOfInvention | A polymer electrolyte for lithium ion battery and polymer battery |
| abstract | In order to overcome the problems of low withstand voltage and low electrical conductivity of polymer electrolytes in the prior art, the present invention provides a polymer electrolyte for lithium ion batteries, comprising polyether polymers and lithium salts, wherein the lithium ions in the lithium salts are combined with The molar ratio of ether bond oxygen atoms in the polyether polymer is more than 1/4; the polyether polymer includes the polymer of formula 1: formula 1: A-R n ; A is a hydrocarbon group or an oxygen-containing hydrocarbon group, and n is integer and n≥1; R is R a and R b are selected from alkylene groups, R x is selected from organic functional groups and halogens; m1 is a natural number greater than 0, n1 is a natural number, when n1 is 0, n≥3. Preferably, the ratio of the total number of carbon atoms in all repeating units of the polyether-based polymer to the total number of repeating units is 4 or less; more preferably, the polyether-based polymer has a branched structure. The present invention also provides a polymer battery comprising the above-mentioned polymer electrolyte. The polymer electrolyte provided by the invention has high withstand voltage and high electrical conductivity, and can significantly improve the performance of the polymer battery. |
