Synthesis and electrochemical properties of FeCO3 with different morphology for lithium-ion battery application

FeCO3 samples (FCO-1 and FCO-2) were successfully fabricated through a facile mixed solvothermal method. They delivered the initial specific discharge capacities of 1563.54 and 1518.09 mAh g−1 at the current density of 100 mA g−1 in the voltage range of 0.01-3 V. FCO-2 behaved much better electrochemical performances than those of FCO-1.248
