abstract
Delithiation followed by lithiation of Li+-occupied (n-type) tetrahedral sites of cubic LiMn2O4 spine! (LMO) at similar to 4V(Li/Li+). (delivering-100 mAhg(LMO)-1) has been used for energy storage by lithium ion batteries (LIBs). In this work, we utilized unoccupied (p-type) octahedral sites of LMO available for lithiation at -3V(Li/Li). (delivering additional -100 mAh gLmo(-1)) that have never been used for LI Bs in full cell configuration. The whole capacity of amphi-redox LMO, including both oxidizable n-type and reducible p-type redox sites, at -200 mAh g(LMO)-1 was realized by using the reactions both at 4 VLi/Li+ and 3 VLi/Li+. Durable reversibility of the 3 V reaction was achieved by graphene-wrapping LMO nanoparticles (LMO@Gn). Prelithiated graphite (LinC6,, n < 1) was used as anodes to lithiate the unoccupied octahedral sites of LMO for the 3V reaction.
