摘要： A flow battery field, an electrode slurry, a slurry electrode, a flow battery, and a stack are disclosed. The electrode slurry comprising electrode particles and electrolyte that contains active substance. Based on 100 pbw active substance, the electrode particles are 10-1,000 pbw. The slurry electrode comprises: a bipolar plate, a current collector, and a slurry electrode reservoir configured to store electrode slurry. In the two opposite sides of the bipolar plate, one side is adjacent to the current collector, and the other side is arranged with a slurry electrode cavity, and flow channels are arranged and extended between the bipolar plate and the slurry electrode cavity, so that the electrode slurry is circulated between the slurry electrode cavity and the slurry electrode reservoir. A flow battery that employs the electrode slurry can provide higher and more stable power output under the same current condition and is lower in cost.
