Abstract:
1. An electrochemical system, comprising: a battery including an anode and a cathode; a charger; a load; a switch mechanism electrically connected to the anode and the cathode through, alternatively, the charger or the load; a first source of a first electrolyte having a first concentration of ions; a second source of a second electrolyte having a second concentration of the ions, wherein the second concentration is greater than the first concentration; and a fluid conveyance mechanism connected between the battery and each of the first source and the second source, wherein the electrochemical system is configured such that: wherein the fluid conveyance mechanism is configured to exchange the first electrolyte with the second electrolyte between charging and discharging of the battery, and the fluid conveyance mechanism is configured to exchange the second electrolyte with the first electrolyte between discharging and charging of the battery, and wherein the switch mechanism is configured such that: during discharging of the battery, the switch mechanism is configured to establish an electrical connection between the anode and the cathode through the load, and disconnect the charger between the anode and the cathode.
