Method for realizing cell switching of multi-electrolyte battery by using conduction of electrolytes

Abstract

The invention relates to the technical field of batteries, and concretely relates to a method for realizing cell switching of a multi-electrolyte battery by using conduction of electrolytes. The multi-electrolyte battery comprises an anode plate, a cathode plate and electrolytes, the electrolytes comprises an anode electrolyte, a cathode electrode and a bridge electrolyte, the anode electrolyte is in contact with the anode plate, the cathode electrode is in contact with the cathode plate, the bridge electrolyte is placed between the anode electrolyte and the cathode electrolyte to form an ion conduction channel, and the bridge electrolyte, the anode electrolyte and the cathode electrolyte are respectively separated by ion exchange films. The electrolytes are controlled to be in a non-conduction state to cut out the ion conduction channel in order to conveniently realize off of the battery, so the cell of the battery also has a battery switching function, thereby dual protection of a circuit is realized, and the safety of the battery is greatly improved; and the self-discharge of the battery can be reduced to a lowest limit when the electrolytes are in a non-conduction state.

Description

technical field [0001] The invention relates to the field of battery technology, in particular to a method for realizing switching of cells of a multi-electrolyte battery by utilizing the conduction of electrolyte. Background technique [0002] Battery (Battery) refers to a part of the space of a cup, tank or other container or composite container that contains an electrolyte solution and a metal electrode to generate current.

Using a battery as an energy source, a stable voltage can be obtained. , stable current, stable power supply for a long time, current that is little affected by the outside world, and the battery structure is simple, easy to carry, easy to charge and discharge, not affected by the external climate and temperature, stable and reliable performance, in modern social life play a significant role in all aspects. [0003] At present, commercialized batteries on the market, such as lithium-ion batteries,...

AI Technical Summary

Problems solved by technology

However, there are two major technical problems in the battery structure of a single electrolyte: (1) Since the cathode and anode of the battery are directly inserted into the electrolyte, the cathode and anode materials of the battery must be compatible with the single electrolyte at the same time. When developing a new battery, It greatly limits the range of selection of battery cathode and anode materials; (2) the composition and concentration of a single electrolyte are difficult to ensure that the electrochemical reactions of the cathode and anode reach the best state (maximum activity) at the same time during battery use, which is not conducive to the performance of the battery. Its maximum electrochemical performance

[0004] In addition, the existing batteries all control the switch of the battery through an external circuit, and the battery cell itself does not have the function of controlling the switch of the battery. Batteries, resulting in accidents, the safety of this type of battery cannot meet the needs of technological development

At the same time, the self-discharge of existing batteries leads to a loss of energy
