Abstract

The invention discloses a sensor for liquid leakage detection of a flow battery. The sensor is characterized in that the sensor is a pattern formed by compositing a conductive material on the surface of an insulation polymer material, wherein the pattern is a non-intersecting conductive material pattern; during liquid leakage detection, the sensor is connected with a power supply and a current detection device; and when the flow battery has liquid leakage, the current detection device detects current and gives an alarm. By compositing the conductive material on the surface of the insulation polymer material, the non-intersecting conductive material pattern is generated to serve as a sensor liquid leakage detection main body; and the sensor is resistant to corrosion, long in service life, cheap in price, simple in processing technology and high in sensitivity.

Description

technical field [0001] The invention relates to the field of liquid flow batteries of chemical energy storage batteries, in particular to a sensor applied to liquid flow battery leakage detection. Background technique [0002] With the advancement of large-scale energy storage applications, the development, design and application of high-power flow batteries have become an inevitable trend. A flow battery consists of a stack, a liquid storage tank, a pipeline system and a battery management system. The stack and the liquid storage tank are connected through a pipeline system to realize the circulation of the electrolyte in the stack. The pipeline system of the flow battery is usually composed of plastic materials, which are combined by welding, threaded connection and flange connection, so there is an inevitable risk of electrolyte leakage. As a power device that can be applied in the field of large-scale energy storage, flow batteries should take effective measures to det...
