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...

Exploiting Anti-T-shaped Graphenes Architecture to Form Low Tortuosity, Sieve-like Interfaces for High-performance Anodes for Li-Based Cells
Jul 23 , 2021
Experimental Section Synthesis of multilayer-graphene nanowalls anchored on carbon paper：The carbon paper used was commercialized Toray carbon paper (CP). Every CP was tailored to be a wafer of 16mm in diameter. Subsequently, the mutilayer-graphene nanowalls would be grown on this CP substrate using RF-PECVD. The parameters were 200W (power), 890℃ (temperature), 30min (time) and 1000Pa (...
