John Goodenough, are proposing a strategy for high-capacity next-generation alkali (lithium or sodium)-ion batteries using water-soluble redox couples as the cathode. The present sodium-sulfur battery operates above 300 °C. A = lithium or sodium (Li or Na), M represents a metal and 1 ≤ n < z. V was developed.

The project will be designed with an innovative smart grid control system to improve grid reliability and enable the integration of wind and other intermittent renewable energy sources. Design, build, and deploy a utility-scale, low-cost compressed air energy storage system to support the integration of renewable energy sources onto the grid.

This allows storage of charge at a higher volumetric or gravimetric density, which translates to a higher stored energy density or storage capacity for a given size or weight. Other work focuses on sodium as an earth-abundant alternative to lithium, but while it could lower cost, sodium ions also carry just a single charge.
