Abstract

A universal rechargeable battery constituted by employing a lithium-ion battery and a control method for the rechargeable battery are provided. The rechargeable battery includes: an outer packaging housing and, sequentially laminated and assembled within the outer packaging housing, a charging/discharging controller, a positive electrode crimping piece, a lithium-ion battery, and a negative electrode end cap. The charging/discharging controller includes: a charging/discharging controller housing and, arranged within the charging/discharging controller housing, a charging/discharging control circuit solder body, an insulating washer, and a charging/discharging controller support frame. The charging/discharging control circuit solder body is soldered to a lithium battery charging/discharging control circuit. The lithium-ion battery charging/discharging control circuit includes: a lithium-ion battery charging control circuit, a lithium-ion battery detection circuit, and a DC-DC step-down regulator discharging circuit that are soldered onto a circuit substrate and electrically connected respectively to the lithium-ion battery, to a positive electrode end cap, and to the negative electrode end cap via the charging/discharging controller housing and the outer packaging housing.
