Temperature-control circulating electrolyte supplementing zinc-oxygen battery system

Abstract

The invention discloses a temperature-control circulating electrolyte supplementing zinc-oxygen battery system. The temperature-control circulating electrolyte supplementing zinc-oxygen battery system comprises a zinc-oxygen battery pack, an oxygen tank and a sealed working battery bin; the zinc-oxygen battery pack is arranged inside the sealed working battery bin and formed by a plurality of single zinc-oxygen batteries; the bottom of each single zinc-oxygen battery is provided with an oxygen channel, and the top is provided with an electrolyte supplementing hole; the oxygen tank is arranged outside the sealed working battery bin and connected with the sealed working battery bin through a pipe, wherein the pipe is provided with a valve; and the sealed working battery bin is provided with a circulating electrolyte supplementing device, a condensing pipe and a temperature control device, wherein the temperature control device is connected with the condensing pipe. The temperature-control circulating electrolyte supplementing zinc-oxygen battery system disclosed by the invention is simple in structure and reasonable in design, adopts the high-temperature batteries, the pure-oxygen high-temperature working environment and the electrolyte cooling, circulating and supplementing system, thus the output power of the zinc-oxygen batteries can be improved by 5 times to meet the requirement and reach the standard of power batteries, so that the zinc-oxygen batteries can be used widely.

Description

technical field [0001] The invention belongs to the field of battery control systems, and in particular relates to a temperature-controlled circulating fluid replenishment zinc-oxygen battery system. Background technique [0002] Zinc-air batteries have attracted widespread attention because of their large capacity, high specific energy, stable working voltage, environmental protection, and cheap materials. It is easy to evaporate and lose in the open space, and the battery leakage is easy to corrode other external objects. The existing zinc-oxygen battery is in a pure oxygen environment, the temperature rises greatly after operation, and the materials used are all non-high temperature resistant materials. The battery materials will be deformed and invalidated due to high temperature, resulting in the battery not working properly. Therefore, a battery cooling system must be installed , but the battery will continue to lose electrolyte due to factors such as temperature rise...

Problems solved by technology

"Zinc Oxygen Battery Pack with Cooling Function" (Patent No. ZL2013101311304) introduces a device that uses coolant circulation to achieve cooling purposes. The defect of this device requires periodic cooling of the battery, so that the battery material that cannot withstand high temperatures can maintain normal working conditions , the battery will evaporate and take away part of the electrolyte during the heating process, and the battery will fail due to the electrolyte being evaporated at the end of the battery operation

The existing zinc-air battery technology uses oxygen in the air to participate in the reaction. The working environment of the battery is a semi-open system. If the electrolyte leaks, it will corrode other objects. If the moisture in the electrolyte is lost, this will inevitably lead to the loss of the electrolyte inside the battery, and the battery will also fail to work because the battery is in a "dry state" in the later stage of operation. The existing zinc-air battery technology is affected by factors such as operating temperature and oxygen concentration. Due to the limitation, the output power of the battery cannot meet the power standard of the existing power battery in the market, and it cannot be used as a power battery to independently supply power to power equipment
