Abstract
A method of transporting a lithium secondary battery includes transporting the battery including an electrode body obtained by winding or laminating a positive electrode and a negative electrode via a separator, and a non-aqueous electrolyte solution in a state where: E/Cp+T3<t . . . (1) where E (J/g) is energy quantity per unit weight of said battery; Cp (J/° C.·g) is the specific heat of said battery; T3 (° C.) is a normal transportation temperature of said battery; and t (° C.) is the lowest temperature at which said battery falls into an unsafe state.
