A Study of Electrochemical Reduction of Ethylene and Propylene Carbonate Electrolytes on Graphite Using ATR-FTIR Spectroscopy
It is well known that when propylene carbonate (PC) is used as the primary solvent with common inorganic salts like LiPF6 there is essentially continuous electrolyte reduction with a graphite electrode at ca. 0.9 V vs. Li/Li, accompanied by gassing and graphite exfoliation. However, co-intercalation and subsequent reduction occurs only with PC and not the chemically closely related solvent ethy...

متن کاملHigh Performance C/S Composite Cathodes with Conventional Carbonate-Based Electrolytes in Li-S Battery
High stable C/S composites are fabricated by a novel high-temperature sulfur infusion into micro-mesoporous carbon method following with solvent cleaning treatment. The C/S composite cathodes show high Coulombic efficiency, long cycling stability and good rate capability in the electrolyte of 1.0 M LiPF6 + EC/DEC (1:1 v/v), for instance, the reversible capacity of the treated C/S-50 (50% S) cat...
متن کاملPropylene Carbonate (PC)-Based Electrolytes with High Coulombic Efficiency for Lithium-Ion Batteries
A homologous series of propylene carbonate (PC) analog solvents with increasing length of linear alkyl substitutes were synthesized and used as co-solvents with PC for graphite-based lithium-ion half cells. A graphite anode reaches a capacity of around 310 mAh/g in PC and its analog co-solvents, with 99.95 percent Coulombic efficiency, similar to the values obtained with ethylene carbonate-base...
متن کاملQuantifying microstructural dynamics and electrochemical activity of graphite and silicon-graphite lithium ion battery anodes
Despite numerous studies presenting advances in tomographic imaging and analysis of lithium ion batteries, graphite-based anodes have received little attention. Weak X-ray attenuation of graphite and, as a result, poor contrast between graphite and the other carbon-based components in an electrode pore space renders data analysis challenging. Here we demonstrate operando tomography of weakly at...
