PNNL: single-crystal nickel-rich cathode holds promise for next-generation Li-ion batteries

Green Car Congress

Scientists at the US Department of Energy’s Pacific Northwest National Laboratory (PNNL) report new findings about how to make a single-crystal, nickel-rich cathode hardier and more efficient. We observe reversible planar gliding and microcracking along the (003) plane in a single-crystalline Ni-rich cathode. —Bi et al.

IDTechEx comments on Volkswagen’s long-term, high-manganese cathode strategy

Green Car Congress

During Volkswagen’s recent Power Day ( earlier post ), the company referred to a long-term strategy of using high-manganese cathodes for its volume segment. A comparison between NMC 811 and three high-manganese cathodes (LMFP, Li-Mn-rich, LNMO) shows that trade-offs in performance are always involved. Source: IDTechEx.
