Dr. Jie Li, Yue Lin, Hehua Yao, Dr. Changfu Yuan and Prof. Jin Liu Tuning Thin-Film Electrolyte for Lithium Battery by Grafting Cyclic Carbonate and Combed Poly(ethylene oxide) on Polysiloxane ChemSusChem 7
Polymer power: A bifunctional polysiloxane thin-film electrolyte for all-solid-state lithium-ion batteries is reported. The cyclic carbonate propylene carbonate (PC) and combed poly(ethylene oxide) (PEO) are simultaneously grafted on the polysiloxane, and the ionic conductivity can be significantly improved by adjusting the PC/PEO ratio. In addition, the electrolyte can be efficiently used in the LiFePO4/Li battery that lights a light-emitting diode lamp.
