A lithium secondary battery includes an electrode body obtained by minding or laminating a positive electrode and a negative electrode via a separator, and a non-aqueous electrolyte solution. The battery satisfies the following Equation (1): E0/Cp + T1 = T2 <t ... (1) where E0 (J/g) is energy quantity per unit weight at the tine of full charging of said battery; Cp (J/.degree.C~g) is the specific heat of said battery; T1 (.degree.C) is a normal use temperature of said battery; T2 (.degree.C) is the highest elevated temperature of said battery; and t (.degree.C) is the lowest temperature at which said battery falls into an unsafe state. |
