Abstract
An energy storage device having improved energy density performance may include an electrolyte having a salt concentration of about 0.6 moles/L (M) to about 0.95M. A final energy storage device product having a total mass of electrolyte that is at least 100% of a saturation quantity of electrolyte sufficient to fully saturate one or more electrode(s) and separator(s) of the device, and below a threshold quantity above the saturation quantity.
Claims32
A final energy storage device product, comprising:
- a container;
- a first electrode;
- a second electrode;
- a separator between the first electrode and the second electrode, wherein the first electrode, second electrode and separator are within the container;
- and
- an electrolyte within the container, the electrolyte having a total mass of at least 100% and less than or equal to 104% of a saturation quantity of electrolyte sufficient to fully saturate the first electrode, the second electrode and the separator.
A method of fabricating an energy storage device, comprising:
- providing a container;
- inserting a first electrode and a second electrode into the container, wherein a separator is positioned between the first electrode and the second electrode;
- and
- adding a final, total mass of electrolyte to the container, wherein the total mass is at least 100% and less than or equal to 104% of a saturation quantity of electrolyte.
