Sandia researchers developing new family of metal-based ionic liquids for low-cost, efficient flow batteries

Green Car Congress

Sandia researchers have developed a new family of electrochemically reversible, metal-based ionic liquid (MetILs) that could lead to non-aqueous redox (reducing-oxidizing) flow-battery energy storage systems ( earlier post ) able to cost-effectively store three times more energy than today’s batteries.

Ioxus Developing Higher Power Density Ultracapacitors

Green Car Congress

Ioxus expects a new set of cells, targeted for release at the end of the year with different terminations, to surpass Maxwell’s large cells in both volumetric and gravimetric power densities. Smaller Ioxus cells offer a power density of 22-28 kW/kg, and larger cells offer densities of 12-15 kW/kg, said Chad Hall, COO of Ioxus.
