A zinc-bromine flowing electrolyte battery comprising positive and negative electrolyte pumps to circulate positive and negative electrolyte within respective circulation paths

摘要

598799 The invention relates to a zinc-bromine flowing electrolyte battery comprising a negative electrolyte pump to circulate negative electrolyte within a negative electrolyte circulation path and a positive electrolyte pump (200) to circulate positive electrolyte within a positive electrolyte circulation path. The flowing electrolyte battery further comprises complexed bromine located within a positive electrolyte tank. The positive electrolyte tank is in fluid communication with the positive electrolyte circulation path. In use, the choice of which of the negative electrolyte pump or the positive electrolyte pump is activated first determines whether a positive electrolyte only or a positive electrolyte and complexed bromine mix are circulated within the positive electrolyte circulation path. A method of regulating the flow of complexed bromine within a positive electrolyte circulation path of a zinc-bromine flowing electrolyte battery is also disclosed.
