WSU, PNNL researchers develop viable sodium battery

Green Car Congress

Although O3-layered metal oxides are promising cathode materials for high-energy Na-ion batteries, they suffer from fast capacity fade. However, the nickel rich O3-NaTMOs suffer from irreversible phase transition at high voltage and limited cycle life, similar to their Li analogues, if not even worse.

Study identifies halogen-free superhalogen electrolytes for Li-ion batteries

Green Car Congress

Most electrolytes currently used in Li-ion batteries contain halogens, which are toxic. An in-depth study based on first-principles calculations by researchers at Virginia Commonwealth University has shown that the anions of commercially available electrolytes for Li-ion batteries are all superhalogens.
