Abstract

The invention relates to a stack frame for a liquid flow battery, which is characterized in that the stack frame is made of a polymer material, has a hollow structure, and its shape has a symmetrical structure in the horizontal and / or vertical directions, so The stack frame has a front and a back, and the surface of the front has: a liquid inlet and a liquid outlet of the electrolyte; an electrolyte diversion groove; a sealing gasket groove; the electrolyte diversion groove and the sealing gasket groove There is no mutual communication, and the electrolyte guide groove is at least partially exposed on the surface of the front of the stack frame, and the electrolyte guide groove allows the electrolyte to flow into or out of the two sides of the bipolar plate or the two sides of the diaphragm of the flow battery. Graphite felt on the side.

Description

technical field [0001] The invention belongs to the field of liquid flow batteries, in particular to the field of preparation of liquid flow battery components. Background technique [0002] Electricity has long been thought of as an instant source of energy that is delivered instantaneously. For decades, the power grid has formed a power supply system based on fossil fuel power generation (commonly known as thermal power) (accounting for 60% of the total power generation capacity of the entire network), mainly through controlling the combustion of coal, oil, natural gas and other substances, and adjusting the drive of thermal energy to mechanical energy. Vary the output efficiency of generators in order to respond instantaneously to the demands of grid loads. [0003] Since the 1990s, the construction of reservoir-type hydropower has effectively reduced the dependence of the power grid on fossil fuel power generation. Through the control of the water level of the reservoi...
