Embodiment Construction

[0009] figure 1 , the piston (6) moves from the starting point A to the direction away from the air plate (1) driven by the piston rod (8), a negative pressure is formed in the battery body, and the suction valve (3) is opened at the same time, the metal material and electrolyte It is sucked into the battery body from the suction port (2), when the piston (6) moves to figure 2 When the far dead point B is shown, it moves back under the drive of the piston rod (8), and at the same time, the suction valve (3) closes, and the piston (6) returns to image 3 When the middle point C is shown, stop the movement. Squeeze the metal material and the electrolyte to fully contact the air plate (1), the casing (7) and the piston (6) to react and generate electricity. When the reaction is over and electricity is no longer effectively generated, the piston (6) moves from the neutral point C to the starting point A under the drive of the piston rod (8), and at the same time the outlet valv...

Abstract

The invention discloses a piston-type metal-air cell, belonging to the cell field, in particular the invention, as an application of power cell, can automatically accomplish the replacement of metal material and electrolyte of the metal cell and the discharging of reaction residue. As for the piston-type metal-air cell, a piston (6) is arranged in the cell body and reciprocates driven by a piston (8), suction, extrusion and reaction of metal material and electrolyte and discharging of reaction residue are accomplished in one round of reciprocation, thus providing stable and sustained electricity quantity.

Description

Technical field: [0001] The invention belongs to the technical field of batteries, in particular to a piston-type metal-air battery that can be used as a power battery. Background technique: [0002] At present, metal-air batteries have attracted people's attention because of their high energy density, continuous and stable discharge, suitable for high-current discharge, and can be used as an alternative energy source in the field of motor vehicles. However, in practical applications, the metal-air battery is only used as an ordinary battery. When the battery is exhausted, the battery is replaced or the metal powder is manually replenished to regain power. This will inevitably bring inconvenience to the user, and it cannot be overcome. Inherent drawbacks of metal-air batteries. First of all, since the metal-air battery uses oxygen for the reduction reaction, the power will drop rapidly after the battery is activated for a long time without use. Even if it is resealed, becau...
