摘要: Abstract Li2FeSiO4 nanoparticles are successfully synthesized via hydrothermal approach, with the process monitored in detail. Structural characterizations by XRD, FTIR, SEM and HRTEM measurements reveal that have a high crystalline degree monodisperse nanoparticle shape size around of 50–200 nm. To further improve electronic conductivity, coated carbon layer using suit polymerization dopamine. Moreover, effect content for electrochemical performance Li2FeSiO4/C is systemically investigated, as result, composite ratio dopamine 3:1 demonstrate best discharge specific capacity 148 mA h g−1 at rate 0.1 C room temperature. Furthermore, temperature 55 °C also it exhibits good 240 mA h g−1at current 0.2 C.
