Overstocked type zinc-air cell monomer

Abstract

The invention provides an overstocked type zinc-air cell monomer, which comprises a pedestal frame, an alkali resistant metal negative plate is hermitically fixed at one side surface of a pedestal frame, the alkali resistant metal negative plate and the pedestal frame form an openmouthed fuel bunker, zinc paste is provided in the fuel bunker, a separator paper is hermitically provided on the fuel bunker; a fluid replacement port is provided on the pedestal frame, a fluid replacement bath communicated with the fluid replacement port is provided on the pedestal frame, a group of liquid inlet ports communicated with the fuel bunker are provided on the pedestal frame at the inner side of the fluid replacement bath, a seal groove is provided on the pedestal frame at outside of the fluid replacement bath, a sealing strip is provided in the seal groove, air electrode is provided over the sealing strip, an overstocking device is arranged on the air electrode in a compaction mode. The overstocked type zinc-air cell monomer solves the problems that the conductive path of the zinc-air cell electron is long, the recovery and regeneration waste time and labor, and the volume is large and easy to deform. The conductive path of cell pack assembled by the cell monomer can be effectively shortened, the flowing cross-sectional area of source is increased, and the internal resistance is reduced. The invention has the advantage of simple components installation and operation, and the loss of the components is reduced.

Description

technical field [0001] The invention relates to an aerodynamic battery, in particular to a stacked zinc-air battery cell. Background technique [0002] The air battery is a battery that uses metal as the negative electrode fuel, oxygen in the air as the oxidant, and converts the chemical energy of the fuel into electrical energy. It is mainly composed of three parts: metal anode, salt or alkali aqueous solution as electrolyte, and air electrode. The current metal-air batteries include magnesium-air batteries, lithium-air batteries, aluminum-air batteries, iron-air batteries, and zinc-air batteries, among which zinc-air batteries are more common. Zinc-air batteries have many advantages such as high energy density, stable use, long storage life, and no noise. They have been gradually used in the fields of electronic product power supply and power supply. The mainstream structure of existing zinc-air battery cells generally adopts the structure of double-sided air electrodes....

AI Technical Summary

Problems solved by technology

The mainstream structure of existing zinc-air battery cells generally adopts the structure of double-sided air electrodes. Some well-known foreign companies use this design. The advantage of this structure is that it can increase the contact area between the single cell and the air, and improve the single cell. Specific power; but when assembled into a battery pack, it must be connected in series through the tabs. The connection methods of the tabs are all welded connections or external plug-in types. There are many disadvantages, mainly as follows: ①The path of electronic conduction is long; ②When the zinc-air battery is recycled and regenerated, the disassembly and assembly and regeneration are complicated and labor-intensive; ③The regenerated material loss is greater; ④When the battery is used in groups, the volume is large, and it is inconvenient to install and use
