Researchers report high performance solid-state sodium-ion battery

Organic cathode offers more reliable contact with electrolyte, a key to stability

24-Apr-2019

Solid-state sodium-ion batteries are far safer than conventional lithium-ion batteries, which pose a risk of fire and explosions, but their performance has been too weak to offset the safety advantages. Researchers reported developing an organic cathode that dramatically improves both stability ...
