Abstract
A main object of the present invention is to provide a lithium salt which can improve its lithium transference number when used as a supporting salt of an electrolyte solution or the like. To attain the object, the present invention provides a lithium salt comprising a chemical structure represented by the following general formula (1): in which R1 to R3 may be same or different from each other and denote a fluoroalkyl group, an alkyl group or a phenyl group.
Claims6
