• energy-density is leading to the development of nanostructured metal oxides [2][3][4], because the nanostructuring allows a high specific capacity [5][6][7][8][9][10][11][12][13]. These considerations brought the development of a new variety of transition metal oxide based systems [14][15][16][17][18][19

In order to obtain

• LIBs with superior performance, numerous strategies to find new materials are currently being explored [3]. Fe3O4 is widely regarded as one of the high energy-density anode materials for LIBs, and is based on the conversion mechanism (Fe3O4 + 8 Li+ + 8 e− ↔ 3 Fe + 4 Li2O) [4][5][6]. The theoretical

• a promising cathode material for rechargeable Li-ion batteries due to the high energy density, improved operating safety, low cost and low toxicity [2]. However, the low electrical conductivity (10−6 S·cm−1) and poor cycling performance of LMO are the main issues associated with this material [3][4
