Abstract

The high price of Co and Ni restricts the development of the lithium-ion battery industry. Reducing the Ni content and eliminating Co is an effective way to lower the cost. In this work, we eliminate the Co in NCM523 cathodes by using a complex concentrated doping strategy. LiNi_0.5Mn_0.4Ti_0.03Mg_0.03Nb_0.01Mo_0.03O₂ shows an unparalleled cost advantage with relatively high specific energy (>720 W h kg^-1) and significantly improved overall performance (96% capacity retained after 1000 cycles). This report offers an important pathway to fabricate cathode materials for low-cost and long-life LIBs.
