1. A battery system to enable control of an electrolyte inside a battery, the battery system comprising:
a rechargeable battery that is not a metal-air battery, wherein the battery includes:
a plurality of electrodes;
the electrolyte;
at least one inlet; and
at least one outlet;
an electrolyte conduit coupled to the at least one inlet and the at least one outlet;
a pump coupled to the electrolyte conduit to circulate the electrolyte through the electrolyte conduit and the battery when the battery is in use;
a battery electrolyte controller coupled to the electrolyte conduit and the pump, wherein the battery electrolyte controller can add electrolyte to the electrolyte conduit and can activate the pump to push the added electrolyte in the electrolyte conduit to the battery;
a pH adjustment reservoir, wherein the battery electrolyte controller can use an acid or base in the pH adjustment reservoir to adjust a pH of the electrolyte in the electrolyte conduit and the battery electrolyte controller can activate the pump to push the electrolyte with the adjusted pH in the electrolyte conduit to the battery; and
a salt concentration reservoir, wherein the battery electrolyte controller can use material in the salt concentration reservoir to adjust a salt concentration of the electrolyte in the electrolyte conduit and the battery electrolyte controller can activate the pump to push the electrolyte with the adjusted salt concentration in the electrolyte conduit to the battery, wherein the pH of the electrolyte and the salt concentration of the electrolyte can be adjusted independently of each other.
