Problems solved by technology

At present, germanium-air batteries are mainly assembled by air battery molds (Phys.Chem.Chem.Phys., 2014, 16:22487-22494), which is large in size, which limits the application of this type of battery in portable electronic products
In addition, assembling with molds is easy to cause liquid leakage problems, mainly because the internal structure is not compact and the sealing process is different

Abstract

The invention discloses a preparation method of a button type germanium air battery. The battery comprises a positive electrode shell, an air electrode, a gel electrolyte, a germanium sheet and a negative electrode shell, wherein a plurality of air holes are formed in the positive electrode shell. The preparation method of the air battery is simple; the gel electrolyte can effectively prevent the electrolyte leakage problem, and the gel electrolyte is poor in fluidity, so that the problem of short circuit caused by contact of a positive electrode and a negative electrode in the battery can be prevented; a germanium sheet is adopted to show a stable long-term discharge curve; and moreover, the material has relatively high power and energy density, and has potential application in the fields of power supply of micro / nano electromechanical systems, hearing aids and the like.

Description

technical field [0001] The invention relates to the technical field of button-air batteries, in particular to a method for preparing button-type germanium-air batteries. Background technique [0002] Lithium-ion batteries, which have high energy efficiency and cycle capability, have captured most of the market share. However, considering its low storage capacity, safety concerns, instability of lithium in humid climates, and low electrochemical efficiency, it is necessary to investigate other battery technologies. Among potential battery candidates, metal-air batteries stand out for their high energy density, in addition to their small size, low cost, light weight, and environmental friendliness. Momentum has high prospects. Despite the high energy of these metal-air batteries, the immediate passivation of most of these metal anodes (e.g., aluminum, magnesium) during discharge severely reduces the available energy and renders the remaining anodes unusable. Therefore, it i...
