Abstract

The invention discloses an integrated plate frame and an electric stack of a liquid flow battery. The integrated plate frame includes a main body of the battery plate frame, a cover plate of the battery plate frame and a bipolar plate. The upper side of the main body of the battery plate frame is provided with a ladder The battery panel frame cover fastens the bipolar plate on the step surface of the slot, and the periphery of the battery panel frame cover fits with the outline of the slot to form a complete plane A connection structure is provided between the bipolar plate and the main body of the battery plate frame and the cover plate of the battery plate frame; a branch channel through which the electrolyte passes is arranged on the cover plate of the battery plate frame, and the branch channel is connected to the battery plate frame cover plate. The main channel of the main body of the battery plate frame is connected. The integrated plate frame of the liquid flow battery and the electric stack made by using the same of the present invention solve the problems of leakage, dislocation and distortion in the assembly and manufacturing process of the battery plate frame, reduce the cost, and improve the reliability of the battery plate frame.

Description

technical field [0001] The invention relates to the technical field of auxiliary facilities of a flow battery, in particular to an integrated frame and stack of a flow battery. Background technique [0002] At present, as a new energy storage method, flow batteries have attracted widespread attention due to their high energy conversion efficiency, long service life and good safety. All-vanadium redox flow battery (hereinafter referred to as vanadium battery) is a very promising green energy storage battery, which does not produce harmful substances in the process of manufacture, use and disposal. With a special battery structure, the active material is stored in the liquid storage tank outside the stack. Compared with the traditional solid-phase battery, the vanadium battery has the advantages of small concentration polarization, large battery capacity, easy adjustment, long life, and high performance. It has the advantages of high current charging and discharging, recyclab...
