Abstract
The invention relates to a sodium-ion battery pack comprising one or more sodium-ion cells and one or more voltage converters. Methods and uses of such a sodium-ion battery pack are also disclosed.
Claims19
A sodium-ion battery pack comprising one or more sodium-ion cells and one or more voltage converters;
- wherein the one or more sodium-ion cells are operable between a minimum operating voltage (cell Vmin) in the range >0.0 V to <2.0 V and a maximum operating voltage (cell Vmax) in the range >3.60 V to <4.30 V;
- and when the sodium-ion battery pack comprises two or more sodium-ion cells, all of the two or more sodium-ion cells have the same cell nominal voltage profile and the same electrochemical design.
A method of accessing the energy available from a battery comprising one or more sodium-ion cells, comprising the steps of:
- a) providing a sodium-ion battery pack comprising one or more voltage converters and one or more sodium-ion cells, wherein the one or more sodium-ion cells are operable between a minimum operating voltage (cell Vmin) in the range >0 to <2.0 V and a maximum operating voltage (cell Vmax) in the range >3.6 V to <4.30 V;
- and further wherein when the sodium-ion battery pack comprises two or more sodium-ion cells, all of the two or more sodium-ion cells have the same cell nominal voltage profile and the same electrochemical design
- b) associating or integrating the sodium-ion battery pack with an electronic application device, and
- c) directly or indirectly operating at least one of the one or more voltage converters to increase the output voltage of the sodium-ion battery pack to more than 60% of battery Vmax;
- wherein battery Vmax is determined as the design maximum output voltage of the sodium-ion battery pack comprising the one or more sodium-ion cells in the absence of the one or more voltage converters.
