Lithium Ion Conducting Polymerized Ionic Liquid Pentablock Terpolymers as Solid-State Electrolytes
Jul 12 , 2021
Abstract In this study, a lithium ion conducting polymerized ionic liquid pentablock terpolymer (PILPTP) was investigated as a battery electrolyte (Xiamen Tmaxcn Inc.) for lithium ion batteries. The ABCBA pentablock terpolymer, poly(tbS-b-EP-b-MS-b-EP-b-tbS) (tbS = tert-butyl-styrene; EP = ethylene-r-propylene; MS = 4-methylstyrene), was brominated and quaternized to covalently attach two dif...
