Journal ArticleDOI
Liquid and Polymer Gel Electrolytes for Lithium Batteries Composed of Room-Temperature Molten Salt Doped by Lithium Salt
TL;DR: The capacity retention after 50 cycles was 93.8% of the initial capacity in the LiEMIBF 4 cell as discussed by the authors, and the cathodic limit of EMIBF 4 was ca. 1.1 V vs. Li/Li + measured by linear sweep voltammetry.
Journal ArticleDOI
Investigation on solvent-free solid polymer electrolytes for advanced lithium batteries and their performance
TL;DR: In this article, seven solvent-free solid polymer electrolytes based on crosslinked polyethers and doped with LiN(CF 3 SO 2 ) 2, were investigated for usage in large-scale rechargeable lithium batteries.
Journal ArticleDOI
Development of solid polymer lithium secondary batteries
TL;DR: In this article, LiBF 4, LiN(SO 2 CF 3 ) 2 (abbreviated as LiTFSI), LiN (SO 2 C 4 F 9 ), and the matrix polymer was cross-linked random copolymer of ethylene oxide and propylene oxide.
Journal ArticleDOI

TL;DR: The self-diffusion coefficients (D) of the anions (19 F NMR) measured by the pulsed gradient spin-echo (PGSE) NMR method showed the time dependency between the short-range anion diffusion and the long-range diffusion.
