Argonne, PNNL researchers develop new cobalt-free cathode for high-energy Li-ion cells

Green Car Congress

O 2 cathode with a predominant, partially-disordered lithiated-spinel structure was prepared by a low-temperature (LT) synthesis. In an open-access paper in the RSC journal Chemical Communications , the team reports that Li/LT-LiMn 0.5 Boyu Shi, Jihyeon Gim, Linze Li, Chongmin Wang, Anh Vu, Jason Croy, Michael M. V and ~4.6
