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...

An Approach to Make Macroporous Metal Sheets as Current Collectors for Lithium-Ion Batteries
Jun 23 , 2021
The freestanding, laminated film was sintered in air by increasing the temperature of the furnace at a slow rate to 1000°C, holding at1000°C for 1 h, and then decreasing the temperature at a rate of5°C/min to room temperature. This high temperature treatment was done to completely burn all carbon and organic materials to generate a porous structure and to simultaneously allow CuO particles to conn...
