Application of Fluorinated Ethylene Carbonate and Chlorinated Ethylene Carbonate in Electrolyte Additives
In the manufacturing and production of batteries,fluoroethylene carbonate(FEC)and chloroethylene carbonate(CEC),when used as additives in electrolytes,can improve the electrochemical window and other performance of the electrolyte,thereby improving the capacity retention rate of the battery after multiple cycles.Therefore,this article first conducts a study on the synthesis of vinyl chlorocarbonate,exploring the impact of different indicators on product manufacturing and production deficiencies.Secondly,using fluoroethylene carbonate as an electrolyte additive,the effects of constant current charge discharge,cyclic voltammetry(CV),and electrochemical impedance spectroscopy(EIS)on LiNi0.5Mn1.5O4/Li,the electrochemical window of the electrolyte,and the performance of Li/MCMB half cells were studied.Finally,through experimental discussion,it was found that fluoroethylene carbonate can effectively serve as an electrolyte additive and be applied in batteries,which is beneficial for improving the overall quality of batteries.
