Aluminum-air battery

Abstract

The invention discloses an aluminum-air battery. The aluminum-air battery comprises an aluminum electrode, an air electrode, an electrolyte and a battery shell, wherein the aluminum electrode comprises a positive contact head and a shell body, the positive contact head is arranged outside the battery shell, the shell body is arranged in the battery shell, a connection rod is arranged in an axial direction of the shell body and is connected with the positive contact head, a plurality of openings are formed in the shell body along a circumferential direction, are uniformly arranged and are partitioned by partition plates, an electrode plate is arranged in the openings and is adaptive to the openings, the electrode plate is movably connected with the shell body, the air electrode comprises anegative contact head and a carbon rod, the negative contact head is arranged outside the battery shell, the carbon rod is arranged in the battery shell, an insertion rod and a groove are arranged atthe top of the battery shell, and the insertion rod is corresponding to the position of the electrode plate. The aluminum-air battery is reasonable in design, simple in structure and rapid in heat dissipation and is simple and convenient to operate, the working area of the aluminum electrode can be adjusted according to power utilization demand, the discharging speed of the aluminum-air battery can be increased, the utilization ratio of the aluminum electrode also can be improved, unnecessary consumption of the aluminum electrode is prevented, the aluminum electrode can be disassembled and replaced, and the cost is reduced.

Description

technical field [0001] The invention belongs to the field of air batteries, in particular to aluminum-air batteries. Background technique [0002] Aluminum-air battery, as the name suggests, is a new type of battery that uses aluminum and air as battery materials. It is a non-polluting, long-lasting, stable and reliable power supply, and it is a battery that is very friendly to the environment. The structure of the battery and the raw materials used can be changed according to different practical environments and requirements. It has great adaptability. It can be used not only on land but also in deep sea. It can be used as a power battery and a battery with long life and high specific energy. The signal battery is a very powerful battery with broad application prospects. [0003] The chemical reaction of the aluminum-air battery is similar to that of the zinc-air battery. The aluminum-air battery uses high-purity aluminum Al (containing 99.99% aluminum) as the positive el...

Problems solved by technology

[0012] However, aluminum-air batteries also have the problem of slower charging

Although the aluminum-air battery contains high specific energy, but the specific power is low, the charging and discharging speed is relatively slow, the voltage lags, the self-discharge rate is large, and the working heat is large, etc.
