Example Embodiment

[0013] Example

[0014] The design of the magnesium-manganese cylindrical dry battery is based on the structure of the zinc-manganese dry battery. The magnesium cylinder is designed with the same thickness except that the cylindrical thickness of the zinc-manganese dry battery is twice as large, so that the production of the magnesium-manganese cylindrical dry battery , Including magnesium cylinder extrusion, battery cell manufacturing and battery assembly adopt the same process and equipment as ordinary zinc-manganese dry batteries. It can be produced according to the equipment, technological process and inspection methods of ordinary zinc-manganese dry batteries.

[0015] The overall shell of the cylindrical magnesium-manganese dry battery is made of high-purity magnesium alloy sheet. The composition of the high-purity magnesium alloy sheet is magnesium as the matrix, containing 2-4% aluminum, 0.3-0.5% manganese, 0.5-2.5% zinc, and harmful impurities iron. , Nickel content does ...

Abstract

This invention puts forward a MgMn dry battery, in which, the anode is highly pure Mg alloy with a bulk drum shell applying thermal extrusion forming and low resistance processed paper membrane. The main performance indication is much higher than that of the same type of ZnMn dry batteries, the uniform working voltage is 0.3-0.4v higher than that of ZnMn batteries suitable for large current discharge.

Description

technical field [0001] The invention relates to a chemical power source, in particular to a magnesium-manganese dry battery whose anode material is magnesium alloy and its manufacturing process. Background technique [0002] At present, the most widely used disposable dry batteries are low-priced zinc-manganese dry batteries. The existing problems of zinc-manganese dry batteries are prominent mercury pollution, low capacity, and not suitable for long-term high-current discharge. At present, both at home and abroad are committed to reducing mercury pollution in batteries, and some countries have achieved mercury-free zinc-manganese dry batteries. China needs to achieve mercury-free in 2005 as planned, but mercury-free batteries are both technically and economically difficult. Alkaline batteries can greatly increase the capacity of dry batteries, but the requirements for production equipment, molds, materials, spare parts, and production environments are higher than those fo...
