Composition and its preferably proportioning causes the electrolyte of composition to have higher electrical conductivity, during applied to lithium battery so that lithium battery
With preferable cycle performance.
Lithium hexafluoro phosphate and dioxalic acid lithium borate are mainly that electrolyte provides lithium ion, and lithium hexafluoro phosphate fusing point 200 is Celsius
Degree, appropriate SEI films are especially formed on Carbon anode on electrode, can effectively to plus plate current-collecting body realize be passivated, and with compared with
Wide electrochemical stability window, and it has appropriate solubility and higher electrical conductivity in nonaqueous solvents, and also its is nontoxic, category
In environmentally friendly material.Dioxalic acid lithium borate has good heat endurance and chemical property, from dioxalic acid lithium borate
Analysis of the molecular structure, it has wider electrochemical window so that its in the charge and discharge process of battery not with positive and negative pole material
Reaction, chemical stability is good, and similarly, it has appropriate solubility and higher electrical conductivity, and its nothing in nonaqueous solvents
Poison, belong to environmentally friendly material.When using the master of properly mixed lithium hexafluoro phosphate and dioxalic acid lithium borate as electrolyte
