Abstract
A flow battery and method of operating a flow battery. The flow battery includes a first electrode, a second electrode and a reaction zone located between the first electrode and the second electrode. The flow battery is configured with a first electrolyte flow configuration in charge mode and a second flow configuration in discharge mode. The first electrolyte flow configuration is at least partially different from the second electrolyte flow configuration.
Claims15
A flow battery, comprising:
- a first electrode;
- a second electrode;
- a reaction zone located between the first electrode and the second electrode, wherein:
- the flow battery is configured with a first electrolyte flow configuration in charge mode and a second flow configuration in discharge mode;
- and
- the first electrolyte flow configuration is at least partially different from the second electrolyte flow configuration;
- a charge mode electrolyte inlet configured to provide at least a portion of the electrolyte into the reaction zone in the charge mode;
- a discharge mode electrolyte inlet configured to provide at least a portion of the electrolyte into the reaction zone in the discharge mode, wherein the discharge mode electrolyte inlet is different from the charge mode electrolyte inlet;
- and
- a common charge and discharge mode electrolyte outlet configured to provide the electrolyte out of the reaction zone in the charge and the discharge modes.

A method of operating a flow battery comprising:
- flowing an electrolyte in a first flow configuration in charge mode and a second flow configuration in discharge mode, wherein the first flow configuration is at least partially different from the second flow configuration;
- and
- wherein:
- the flow battery comprises a flow cell including a first electrode, a second electrode, and a reaction zone located between the first electrode and the second electrode;
- in the charge mode, the electrolyte is provided from a charge mode electrolyte inlet into the reaction zone, and from the reaction zone into a common electrolyte outlet;
- in the discharge mode, at least a portion of the electrolyte is provided from a discharge mode electrolyte inlet into the reaction zone, and from the reaction zone into the common electrolyte outlet;
- and
- the discharge mode electrolyte inlet is different from the charge mode electrolyte inlet.
