摘要：

"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.
