An electrode-electrolyte separation structure based on oxygen-metal battery

Abstract

The invention relates to an electrode-electrolyte mutual separation structure based on an oxygen-metal battery. According to the electrode-electrolyte mutual separation structure, an electrode is inserted into a closed battery box filled with an electrolyte, a load is externally connected through a conducting wire, a liquid discharge port and a liquid inlet are arranged, and the liquid discharge port is connected to a liquid storage box through an electrolyte circulation device and then is connected to the liquid inlet so as to form a circulation, wherein the electrolyte normally circulates in the circulation through the electrolyte circulation device when the battery works, and when the work of the battery is stopped, the electrolyte in the battery box is discharged into the liquid storage box so as to prevent the self-corrosion reaction; or the liquid storage box is not arranged, the liquid discharge port is directly connected to the liquid inlet so as to form the circulation, wherein the electrolyte circulates in the device when the battery works, and when the work of the battery is stopped, the electrode in the battery box rises and leaves the electrolyte so as to prevent the self-corrosion reaction. According to the present invention, the electrode-electrolyte mutual separation structure can be used for the oxygen-metal batteries (including air batteries), can be used for the transformed electrolyte circulation type battery, and has characteristics of simpleness and convenience.

Description

technical field [0001] The invention relates to an electrode-electrolyte separation structure based on an oxygen-metal battery, which is mainly divided into two types: a draining type and an electrode lifting type. The oxygen-metal batteries here include air batteries. Background technique [0002] The emergence of batteries has greatly facilitated the power supply for outdoor operations. People have successively developed batteries such as lead storage batteries, nickel-metal hydride storage batteries, lithium-ion batteries, polymer lithium batteries, and fuel cells. However, due to their more or less problems such as "low voltage, not suitable for excessive discharge, unfriendly environment, scarce raw materials, high price, high dependence on infrastructure, unsafe, and fewer cycles", although air batteries have overcome The above problems, but there is a strong self-corrosion behavior when the battery is not discharged, which affects the overall energy efficiency of the...

Problems solved by technology

However, due to their more or less problems such as "low voltage, not suitable for excessive discharge, unfriendly environment, scarce raw materials, high price, high dependence on infrastructure, unsafe, and fewer cycles", although air batteries have overcome The above problems, but there is a strong self-corrosion behavior when the battery is not discharged, which affects the overall energy efficiency of the battery

Although the alloying of metal anodes in air batteries reduces the rate of self-corrosion, it cannot be completely eradicated. Therefore, it is particularly important to develop a discharge method without self-corrosion behavior.
