Berkeley Lab researchers shed light on how lithium-rich cathodes work, opening the door to higher capacity batteries

Green Car Congress

The traditional design paradigm for Li-ion battery cathodes has been to create compounds in which the amount of extractable Li + is well balanced with an oxidizable transition metal (TM) species (such as Mn, Fe, Co or Ni) to provide the charge-compensating electrons, all contained in an oxide or sulfide host.
