Univ. of Texas researchers propose lithium- or sodium-water batteries as next generation of high-capacity battery technology; applicable for EVs and grid storage

Green Car Congress

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. —Lu et al.

New nanoparticle copper compound cathode could enable low-cost, long-life and high-power potassium-ion batteries for grid storage

Green Car Congress

Yi Cui has developed nanoparticle copper hexacyanoferrate (CuHCF) battery cathode materials that demonstrate long cycle life and high power for use in grid storage applications. Short-term transients, including those related to wind and solar sources, present challenges to the electrical grid. A team at Stanford led by Prof.

Aqua Metals is building a more sustainable battery recycling ecosystem

Charged EVs

Pyrometallurgy, which traditionally doesnā€™t recover carbon or lithium, seems likely to be phased out. We take that black mass as the input to our process, which is then powered by 100% renewable, carbon-free energy. The whole batteries go in, so the plastics get burned, the carbon gets burned, thereā€™s a lot of emissions.
