It then underwent a second cycle of water splitting test to determine if the electrode was re-usable and how much the performance varied. This provided additional evidence that the film is re-useable, although the amount of hydrogen produced is almost halved, the researchers said. After a further 6?hours —Pawar and Tahir.

ion Ventures and LiNa Energy conclude successful test of solid-state sodium-nickel battery platform

Green Car Congress

Using this skill set, they developed the LiNa Platform, an innovative re-engineering of the operationally proven sodium-nickel-chloride (Na-NiCl 2 ) chemistry, where power is produced by sodium ions conducting across a fast sodium ion conducting ceramic membrane in the solid-state.

In addition, the international research and development team is working on the low-cost iron-salt battery, the properties of which make it particularly suitable for ensuring base load capability for wind and solar farms. The reaction is fully reversible, and iron is re-dissolved in the electrolyte during discharging.

KIST team develops activation strategy for magnesium metal enabling efficient operation of Mg batteries

Green Car Congress

Despite these advantages, the difficulty of efficiently charging and discharging magnesium metal due to its reactivity with electrolytes has hindered its commercialization. It will increase the possiblity of low-cost, high-energy-density magnesium secondary batteries based on common electrolytes suitable for energy storage systems (ESS).
