    摘要： A lithium secondary battery includes an electrode assembly including a cathode and an anode facing the cathode, a case accommodating the electrode assembly, an electrolyte accommodated in the case together with the electrode assembly, and an electrolyte storage unit inserted into the case to supply a supplementary replenishment. The electrolyte storage unit includes a first unit including a first body having a tubular structure and first holes formed through the first body, and a sub-unit including a tubular body and sub-holes formed through the tubular body. The sub-unit is inserted into the first unit so that the sub-holes are offset from the first holes.

    摘要： A secondary battery is provided in the present application. The secondary battery includes an electrode assembly including a cathode and an anode facing the cathode, thermoelectric elements columns arranged on a surface of the electrode assembly, and a circuit structure that electrically connects the thermoelectric element columns. The circuit structure includes a series/parallel switching unit configured to switch a connection between the thermoelectric element columns from a series connection to a parallel connection or from a parallel connection to a series connection. The thermoelectric element columns are connected selectively in parallel or in series to improve rapid charging and life-span properties.
