Abstract

The invention provides a zinc and manganese reserve battery and a manufacture method of the zinc and manganese reserve battery. The zinc and manganese reserve battery comprises a battery outer shell and an electrolyte storing box. The electrolyte storing box is connected with the battery outer shell through an electrolyte pipeline, and a positive electrode leading-out end and a negative leading-out end are arranged on the surface of the battery outer shell. An electrolyte is arranged in the electrolyte storing box, and a manganese positive electrode and a zinc negative electrode are arranged in the battery outer shell. The manganese positive electrode comprises electrolysis MnO2 and electric conduction carbon materials. The part ratio, by weight, of the electrolysis MnO2 and the conduction carbon materials is 75-85/9-25. The zinc and manganese reserve battery can be rapidly activated, output power is large, and long-time continuous work is achieved. Electric energy is not output when the zinc and manganese reserve battery is stored, self discharging does not exist, and therefore energy consumption is not produced. After the zinc and manganese reserve battery is stored for a long time, enough energy can be provided when the zinc and manganese reserve battery is activated.

Description

technical field [0001] The invention belongs to the field of reserve batteries, in particular to a zinc-manganese reserve battery and a preparation method thereof. Background technique [0002] In the past, a large number of lead-acid batteries, lithium-ion batteries, and nickel-metal hydride batteries were used as power guarantees for backup power sources in coal mines and underground mines. However, in use, lead-acid batteries need to be float-charged during storage, and there is a hidden danger of hydrogen and oxygen evolution, which is not conducive to underground safety; while lithium-ion batteries and nickel-metal hydride batteries have always been restricted by the uniformity of their monomers. , and there may even be a danger of spontaneous combustion and explosion during use. Therefore, it is necessary to provide a new backup battery. Contents of the invention [0003] Based on this, it is necessary to provide a zinc-manganese reserve battery capable of rapid ac...
