## Abstract

Particular embodiments described herein provide for a privacy cover in an electronic device. The battery system can be configured to monitoring one or more condition of a battery using a battery electrolyte controller that is separate from the battery, adjusting one or more properties of an electrolyte in an electrolyte conduit, where the electrolyte conduit is coupled to an inlet and an outlet on the battery, and activating a pump to move the electrolyte with the adjusted one or more properties into the battery.

## Claims

### Claim 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.

### Claim 2 (depends on 1)

The battery system of claim 1, wherein the battery electrolyte controller is coupled to positive and negative terminals of the battery, monitors one or more conditions related to the battery, and adjusts one or more properties of the electrolyte based on the monitored one or more conditions related to the battery.

### Claim 3 (depends on 1)

The battery system of claim 1, wherein the battery also includes an electrolyte level sensor.

### Claim 4 (depends on 1)

The battery system of claim 1, wherein the battery also includes an electrolyte pH level sensor.

### Claim 5 (depends on 1)

The battery system of claim 1, wherein the battery also includes an electrolyte salt concentration sensor.

### Claim 6 (depends on 1)

The battery system of claim 1, wherein the battery is an aqueous rechargeable battery.
