Size design of lithium-ion battery with high mass specific energy——Battery mass formula

A size designing method of battery with high mass specific energy and a battery mass formula were provided. Correctness and accuracy, usage and significance of the battery mass formula were proved and expounded respectively by an example. It was shown that there is minimum for the battery mass formula in its domain, and that theoretical basis for size designing battery with high mass specific energy can be obtained by calculating minimum of the battery mass formula.
