Vanadium / polyhalide redox flow battery

摘要

The invention relates to a redox flow cell containing a polyhalide/halide redox couple in the positive half-cell electrolyte and a V(III)/V(II) redox couple in the negative half-cell electrolyte. The invention also relates to a method of producing electricity by discharging the fully charged or partially charged redox flow cell, and a method of charging the discharged or partially discharged redox flow cell.
