Abstract

Li3VO4 has been proven to have great potential as an alternative anode for lithium-ion batteries (LIBs), while the high cost of lithium resources and limited reserves inhibit its radiance. LiVO3 with fewer lithium atoms has been widely studied as a cathode for LIBs. The lithium storage mechanism and synthesis method of the LiVO3 anode are still in the preliminary stage. Herein, LiVO3-N2 was prepared through hydrothermal method and subsequent annealing in nitrogen atmosphere for the first time. As an anode, the LiVO3-N2 presents high capacity of 715 mAh g−1 after 300 cycles at 0.2 A g−1, and long cycling life of ~ 120 mAh g−1 after 3000 cycles at 5.0 A g−1, outperforming all reported LiVO3-based anode materials. Even after 6-period rate property testing from 0.2 to 2.0 A g−1 over 310 cycles, the LiVO3-N2 electrode still resumes high capacity of 520 mAh g−1 when the current returns to 0.2 A g−1. Such excellent electrochemical performances are attributed to the high and gradually increasing pseudocapacitive contribution storage upon cycling originated from self-adaptive reaction kinetics. The novel approach to LiVO3 synthesis and the remarkable lithium storage performance of the LiVO3-N2 provide impetus for further development of LiVO3 anode.Graphical abstractThe developed LiVO3-N2 anode presents much superior lithium storage performance than the conventional LiVO3-Air anode.[graphic not available: see fulltext]
