Novel monomer aluminum air battery

Abstract

The invention discloses a novel monomer aluminum air battery. An aluminum electrode plate is inserted into a battery fluid chamber; a negative electrode plate is arranged on the aluminum electrode plate; positive electrode plates are arranged on the battery fluid chamber; the positive electrode plates cover front and rear surfaces of the battery fluid chamber; a plurality of bosses made of insulating materials are arranged on front and rear surfaces of the positive electrode plates; a conductive lead-out strip is connected onto each positive electrode plate; the negative electrode plate serving as a sealing cover plate of the battery fluid chamber is arranged at the upper end of the aluminum electrode plate; two ends of the negative electrode plate extend outwards to form a negative electrode contact section; an elastic piece is arranged on the battery fluid chamber below the negative electrode contact section. According to the air battery disclosed by the invention, a connection formbetween monomer batteries is improved, and compared with conduction in the prior art, the air battery in the invention is simpler in operation and processing technology, the operation is more convenient and more feasible during replacement of the aluminum electrode plate, and a failure risk is greatly reduced; due to the arrangement of the bosses, a condition of positive electrode contact short circuit is avoided, and swelling in opposite directions is offset, so that the overall structure of the battery pack is compact, and miniaturization is facilitated.

Description

technical field [0001] The invention relates to the technical field of chemical batteries, in particular to a novel single aluminum-air battery. Background technique [0002] Aluminum-air battery is a clean new energy battery, which obtains electrical energy through the electrochemical reaction between electrolyte and aluminum. In the process of converting chemical energy into electrical energy, aluminum is used as the negative electrode of the battery, and it is set as a plate-shaped electrode plate, which will be continuously consumed during the reaction process. Since each single battery in this chemical reaction can only generate a DC voltage of about 1V, multiple single batteries are connected in series to form a battery pack during use, and 12V, 24V, 48V, 12V, 24V, 48V, 96V and other voltages. [0003] In the prior art, a plurality of single cells of a battery pack are usually connected in series by welding with metal wires. This connection method will cause the fol...

AI Technical Summary

Problems solved by technology

This connection method will cause the following problems: each single battery needs to be welded, so the processing technology is complicated, it takes too much man-hours, and the manufacturing cost increases; too many welding points lead to many failure points; because the aluminum plate of the battery is The negative electrode needs to be replaced due to chemical consumption during the use of the battery, which requires re-welding after each replacement before it can be used next time, resulting in serious inoperability

Due to the pressure given to the liquid by the water pump system, and a certain amount of gas will be generated in the liquid cavity of each single battery during the reaction process, this will cause the liquid cavity of the single battery to expand to both sides, and the adjacent two cells of the stack The expansion of the liquid cavity of the bulk battery leads to an increase in the distance between two adjacent single cells of the stack (the outside of the liquid cavity is the positive electrode, and if it contacts, it will cause electrical failures such as short circuits), which leads to a substantial increase in the overall size of the stack

However, the large increase in the size of the electric stack is not convenient for the miniaturization of the product, which affects the post-processing and production of the product and the limitations of the user's use.
