Argonne National Lab Breakthrough Cathode Innovation for Sodium-Ion Batteries
by Brian Wang from NextBigFuture.com on (#6K7PH)
Argonne National labs has a new cathode material for sodium-ion batteries. Johnson's team invented a layered oxide cathode tailored for sodium-ion batteries. This variation on the NMC cathode is a sodium nickel-manganese-iron (NMF) oxide with a layered structure for efficient insertion and extraction of sodium. The absence of cobalt in the cathode formula mitigates cost, ...
