A redox mediator-containing electrolyte incorporated into a battery cell is described. The redox mediator-containing electrolyte includes water, at least one hydroxide salt dissolved in the water, and at least one redox mediator incorporated into the water. The at least one redox mediator increases at least one of a rate capability or a cycle life of the battery cell by at least 10%. Also described are battery cells that may include a positive electrode, a negative electrode, and the redox mediator-containing electrolyte. The battery cells may further include an ion-selective material that diffuses hydroxide ions through the material at a faster rate than at least one of the redox mediators.
