Problems solved by technology

These two heat dissipation methods are related to the heat dissipation area, wind speed, and ambient temperature. If you need to increase the heat dissipation, you need to (1) increase the air intake wind speed if you want to increase the wind speed. The power of the fan, and the size of the fan will also increase accordingly, which brings about the increase of power consumption of auxiliary facilities and the increase of the volume of the battery system

Embodiment 1

[0024] The aluminum / air battery cell consists of a battery cover, a battery case, an aluminum anode and two air cathodes, where the two air cathodes are placed on opposite sides of the battery case, and the aluminum anode and the battery cover are fixed Vertically inserted into the battery case, and kept parallel to the air cathode, the battery upper cover is made of nickel material, and the outer surface of the battery upper cover is evenly provided with a Heat sink fins made of nickel material. The length of the heat dissipation fins is equal to the length of the battery cover, which is 21mm, and the width is 1mm. The distance between two adjacent heat dissipation fins is 2mm. The heat dissipation fins are arranged in parallel and perpendicular to the upper cover of the battery. The aluminum anode is quickly connected to the battery upper cover through the oppositely arranged slots; the battery case and the battery upper cover are sealed and connected to the sealing line th...

Abstract

A metal / air battery comprises a battery cover, a battery shell, a metal anode and two air cathodes. The battery shell is a hollow container with the upper end opened. The two air cathodes are arranged inside the battery shell. The two air cathodes are arranged relatively parallel to each other. The battery cover is in snap-fit with the opening end of the battery shell. The battery is provided with radiating fins. In comparison with the prior art, the metal / air battery has the following advantages: the single battery itself dissipates heat through the batter cover which has high thermal conductivity and is prepared from a corrosion-resistant material; heat generated by battery reaction is directly educed from the inside of the battery; the heat-dissipation effect of the battery is further raised and the damage of heat gathered inside the battery shell to the cathodes and the battery shell is effectively avoided; and battery performance is further enhanced and reliability and durability of the battery are improved.

Description

technical field [0001] The invention relates to a metal / air battery. Specifically, it is a metal / air battery with good heat dissipation performance such as magnesium, aluminum, zinc, etc. Background technique [0002] A metal / air battery is an electrochemical reaction device that uses metal (such as magnesium, aluminum, zinc, etc.) as the anode fuel, oxygen in the air as the oxidant, and lye or neutral brine as the electrolyte solution. my country's magnesium, aluminum, zinc and other metals are rich in reserves and low in price. Therefore, metal / air batteries have broad application prospects in many fields of mobile power sources such as communication power sources, field emergency power sources, lighting power sources, and reserve power sources. Metal / air batteries have high energy density, high safety, no pollution to reactants and products, quiet and concealed operation, safe and convenient metal fuel storage, transportation and portability, and long dry storage time, a...
