Lithium ion (Li-ion) batteries have been widely applied to portable electronic devices and hybrid vehicles. In order to further enhance performance, the search for advanced anode materials to meet the growing demand for high-performance Li-ion batteries is significant. Fe3C as an anode material can contribute more capacity than its theoretical one due to the pseudocapacity on the interface. However, the traditional synthetic methods need harsh conditions, such as high temperature and hazardous and expensive chemical precursors. In this study, a graphitic carbon encapsulated Fe/Fe3C (denoted as Fe/Fe3C@GC) composite was synthesized as an anode active material for high-performance lithium ion batteries by a simple and cost-effective approach through co-pyrolysis of biomass and iron precursor. The graphitic carbon shell formed by the carbonization of sawdust can improve the electrical conductivity and accommodate volume expansion during discharging. The porous microstructure of the shell can also provide increased active sites for the redox reactions. The in-situ-formed Fe/Fe3C nanoparticles show pseudocapacitive behavior that increases the capacity. The composite exhibits a high reversible capacity and excellent rate performance. The composite delivered a high initial discharge capacity of 1027 mAh g−1 at 45 mA g−1 and maintained a reversible capacity of 302 mAh g−1 at 200 mA g−1 after 200 cycles. Even at the high current density of 5000 mA g−1, the Fe/Fe3C@GC cell also shows a stable cycling performance. Therefore, Fe/Fe3C@GC composite is considered as one of the potential anode materials for lithium ion batteries.

Composites of {[(1-x-y) LiFe0.333Ni0.333 Co0.333] PO4}, xLi2FePO4F and yLiCoPO4system were synthesized using the sol-gel method. Stoichiometric weights of the mole-fraction of LiOH, FeCl2·4H2O and H3PO4, LiCl, Ni(NO3)2⋅6H2O, Co(Ac)2⋅4H2O, as starting materials of lithium, Iron, Nickel , and Cobalt, in 7 samples of the system, respectively. We exhibited Li1.167 Ni0.222 Co0.389 Fe0.388 PO4 is the best composition for cathode material in this study. Obviously, the used weight of cobalt in these samples is lower compared with LiCoO2 that is an advantage in view point of cost in this study. Charge-discharge haracteristics of the mentioned cathode materials were investigated by performing cycle tests in the range of 2.4–3.8 V (versus Li/Li+). Our results confirmed, although these kind systems can help for removing the disadvantage of cobalt which mainly is its cost and toxic, the performance of these kind systems are similar to the commercial cathode materials in Lithium Ion batteries (LIBs).
