Abstract

The invention discloses a shell structure for a liquid-flow single battery system. The shell structure for the liquid-flow single battery system comprises a positive electrode frame, a negative electrode frame, a membrane frame, a positive electrode plate, a negative electrode plate and two O-type seal rings, wherein the axes of the positive electrode frame, the negative electrode frame, the membrane frame, the positive electrode plate, the negative electrode plate and the O-type seal rings are located on a same horizontal straight line, the positive electrode frame, the negative electrode frame, the membrane frame, the positive electrode plate and the negative electrode plate are sequentially overlapped in the specified direction, the positive electrode plate is fixed inside the positiveelectrode frame, and the negative electrode plate is fixed inside the negative electrode frame; one O-type seal ring is arranged between the positive electrode plate and the membrane frame, and the other O-type seal ring is installed between the negative electrode plate and the membrane frame; the positive electrode frame and the negative electrode frame are fixed to the membrane frame in an extruded-sealed manner through the two O-type seal rings. The shell structure for the liquid-flow single battery system has good sealing performance, the energy density of the single battery system is effectively improved, the whole structure is simple and easy to disassemble, and the shell structure is suitable for liquid-flow battery performance research.

Description

technical field [0001] The invention belongs to the technical field of liquid flow batteries, and in particular relates to a housing structure for a single flow battery system. Background technique [0002] Flow battery is a new type of electrochemical energy storage device. It is a high-performance battery that uses the positive and negative electrolytes to separate and circulate separately, and finally realizes ion exchange through the exchange membrane to finally generate electricity. It is mainly used in battery peak shaving, large-scale new energy power generation systems, emergency power systems, and energy storage in remote areas, and can even be used as a power system for new energy vehicles and military facilities. Compared with traditional energy storage methods, it has the characteristics of high energy conversion efficiency, long cycle life, and large capacity. [0003] The liquid flow single battery system is mainly composed of a single battery case, a circulat...
