OVERVIEW

Rechargeable battery technologies based on multivalent transition metal electrodes coupled to charge carrier ions can deliver breakthroughs in energy density, leap-frogging current state-of-the-art Li-ion battery technology.

 

Potential

Space Charge’s existing single-layer prototype nanobattery exhibits energy density at the low range of advanced batteries with power density similar to a capacitor. None of the other technologies depicted can scale as in-chip power in integrated circuitry. 

Feasibility

Over the next 3 to 5 years, lithium battery chemistries will exhaust optimizable potential to improve energy density — a potential to which lithium has owed to its position as the smallest and lightest solid metal in the periodic table. Li-Ion has a single electron in its valence shell, providing a single charge-carrying ion. Our proposed battery technology for manufacturing using ALD selective deposition to interdigitate electrodes and refine intercalation. Using thin film direct ionic conduction enables a nearly loss free ion exchange to further improve the energy density.
