“…LVO has been studied for a long time as a cathode active material for rechargeable Li-based batteries [42,43,44,45,46,47,48,49], because of the large Li + storage capacity of 300 mAh g −1 at an averaged potential around 2.5 V vs. Li/Li + . It is noted that the reaction of LVO starts from discharging (i.e., Li + insertion) process, which is different from other conventional cathode materials for LiBs such as LiCoO 2 , LiMn 2 O 4 and LiFePO 4 which contain Li + for the charge and discharge reaction.…”
