“…Although LiMn2O4 is inexpensive and safer than LiCoO2, it has a lower capacity as compared to other cathode materials that form α- NaFeO2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 16 structure [205][206][207][208]. This high capacity is mostly attributed to phase changes that occur during cycling [209][210][211][212][213]. Vanadium based cathode on the other hand, have high capacities but relatively low voltages (i.e.…”

“…Another of the challenges in the use of LiMn 2 O 4 as a cathode material is that phase changes can occur during cycling. [16][17][18] Various strategies have been proposed and tested to avoid some of these drawbacks, and scientists are still struggling to minimize these problems. Recently, iron-based compounds have attracted much attention as active materials for rechargeable Li batteries.…”

“…It means that the partial structural transformation from the layered rhombohedral structure to the spinel structure unavoidably occurs during electrochemical cycling, which was also confirmed previously in o-LiMnO 2 cathode materials. 26,27 However, the partial cation doping or polyanion doping in the layered rhombohedral structure can slow down capacity decay to a certain extent. The high-rate discharge capacity is measured and presented in Fig.…”
