The instant invention is to an electrolyte consisting essentially of a salt mixture and a solvent mixture. The solvent mixture consists essentially of ethylene carbonate and dimethyl carbonate and the salt mixture consists of 60-90% lithium tetrafluoroborate and 10-40% lithium hexafluorophosphate. A ...
aFinally, coin-type cells were assembled in a glove box (Braun unilab , Germany 2002 ), which used lithium foil as the counter electrode, celgard 2400 as the separator, and LiPF6 mixed with 1:1 ratio of ethylene carbonate and dimethyl carbonate as the electrolyte. 终于,硬币类型细胞在手套盒...
Ethylene carbonate is synthesized by the reaction of dimethyl carbonate and epichlorohydrin. The specific steps are as follows: first, dimethyl carbonate and catalyst are added to the reaction kettle, heated to a certain temperature, and then epichlorohydrin is added. After several hours of reaction,...

Theoretical investigations on oxidative stability of solvents and oxidative decomposition mechanism of ethylene carbonate for lithium ion battery use. The electrochemical oxidative stability of solvent molecules used for lithium ion battery, ethylene carbonate (EC), propylene carbonate, dimethyl carbonate... ...
Dimethyl carbonate can be synthesized from ethylene carbonate and methanol by using hydrotalcite-type materials as base catalysts. Especially, Mg-Al hydrotalcite-type materials with low Al concentration in brucite-like layers and high OHproportion in the intercalated anions give high yield of dimethyl ...
Ethylene carbonate (EC) is a new type of chemical material. It is an organic solvent with excellent properties and can dissolve many kinds of polymers. In addition, it can be used as an organic intermediate in dioxylation reaction instead of ethylene oxide, an...
