Hybridized cobalt/manganese vanadates as high-performance anodes in lithium ion battery

Less cobalt is an unstoppable trend especially in lithium ion batteries (LIBs). In this study, by doping Mn for cobalt vanadate through facile hydrothermal reaction, the novel mixed Co/Mn vanadates are obtained balancing performance and cost. The 67%Mn-based vanadates, of optimized element ratio, achieve a high initial discharge capacity of 1193 mAhg(-1) and maintain 935 mAhg(-1) after 500 cycles at 0.5 A/g. (C) 2020 Elsevier B.V.
