Abstract

The invention discloses a voltage-adjustable rechargeable AAA lithium battery, which is characterized by comprising a positive electrode cover, a metal casing, a battery cell and a variable pressure circuit board. The battery cell is arranged in the metal casing, the positive electrode cover is arranged at the upper end of the metal casing, the variable pressure circuit board is arranged between the battery cell and the positive electrode cover, and the variable pressure circuit board is connected with the battery cell. The positive electrode cover comprises a metal upper cover plate, a rotating block, a plastic cover plate, a first metal link block and a second metal link block, wherein the metal upper cover plate is provided with a positive electrode cap, the metal upper cover plate is arranged on the plastic cover plate, and the rotating block is arranged between the metal upper cover plate and the plastic cover plate. A lithium battery base voltage level and a 1.5 V standard voltage level can be selecte by that left and right stroking of a metal shift fork, so that the problem that the 3.7 V, 3.2 V and 2.4 V base voltage level of the lithium battery are not common with the 1.5V conventional standard battery is solved.

Description

technical field [0001] The invention belongs to the technical field of lithium batteries, in particular to a rechargeable AAA lithium battery with adjustable voltage. Background technique [0002] Lithium titanate battery is a lithium-ion battery negative electrode material - lithium titanate, which can be combined with lithium manganate, ternary materials or lithium iron phosphate and other positive electrode materials to form 2.4V or 3.2V, 3.7V lithium-ion secondary batteries . In addition, it can also be used as a positive electrode to form a lithium secondary battery with a metal lithium or lithium alloy negative electrode. Due to the high safety, high stability, long life and green environmental protection characteristics of lithium titanate. However, in the prior art, when different voltages are required, batteries with different specifications and voltages can only be selected for replacement, resulting in increased cost and troublesome replacement.
