Metal/air battery system

Abstract

The invention discloses a metal / air battery system. The metal / air battery system comprises a support skeleton, a reaction vessel with an upper opening, a battery upper cover, a metal anode and an aircathode; the support skeleton is sequentially provided with a connection part and a support part from top to bottom; the outer lateral surface of the battery upper cover is fixedly connected with theupper part of the connection part; the connection part is of a telescopic structure; the outer lateral surface of the reaction vessel, which is positioned on the same side of the battery upper cover,is rotationally connected with the lower part of the connection part; a height of the support part is adjustable; the battery upper cover is provided with at least one filling port communicated with the reaction vessel; and at least one solid electrolyte storage unit is arranged on the outer upper part of the battery upper cover. The metal / air battery provided by the invention has the following advantages that: the endurance using flow of a metal / air battery is simplified, and the metal / air battery system is easy to discharge and replace an electrolyte and a product; and the solid electrolytestorage unit is integrated on the battery upper cover, so as to reduce battery accessories and simplify the electrolyte configuration process.

Description

technical field [0001] The invention relates to a metal / air battery system, in particular to a metal / air battery system which is easy to clean and replace electrolyte. Background technique [0002] Metal / air battery is an electrochemical reaction device that uses metal (such as magnesium, aluminum, zinc, etc.) The price is low, so 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 in my country. [0003] Taking magnesium-air batteries as an example, the corresponding products (metal hydroxide metal oxides) will be produced during the discharge process and exist in the form of precipitates in the electrolyte solution, which will reduce the performance of the battery, so that the electrolyte solution needs to be replaced frequently, and the electrodes need to be cleaned. . [0004] The significant advantage of the metal...

Problems solved by technology

[0004] The significant advantage of the metal / air battery is its high specific energy, and the specific energy gradually increases with the prolongation of fuel use time. Therefore, as a portable power supply, the use mode of replacing the electrolyte with a large-capacity anode is often used, and the metal hydroxide is oxidized during use. The removal of precipitates and the replacement of electrolytes are complicated and cumbersome, which limits the popularization and use of batteries.

The replacement of the electrolyte requires additional accessories to fill the solid or liquid electrolyte, which makes the maintenance work of the battery complex and large
