Ultrahigh Power and Energy Density in Partially Ordered Lithium-ion Cathode Materials


The tremendous growth of Li-ion batteries for energy storage has put strain on the supply of
metals such as Ni and Co. In a recent paper in Nature Energy the Ceder Group at UC Berkeley
report that oxyfluorides that contain only earth-abundant manganese and which have
substantial lithium excess and partial spinel-like cation order display both exceptionally high
energy and power. This discovery opens up the possibility of less expensive and more
abundant energy storage. Read more here.
