【Task】 Lithium-ion batteries have a low rate of discharge or power, have a limited cycle life, and have safety issues due to the flammability of the components. Therefore, there is a need to provide an improved secondary battery. [Solution] A rechargeable battery is provided such that the positive electrode includes graphite, the negative electrode also includes graphite, and the electrolyte is a solution of lithium bromide in lactone.
