We developed a simple but effective protocol to construct uniform FePO4 coating layer on various substrates. By controlling the precipitation kinetics, we were able to form uniform FePO4 nanoshells with its thickness precisely defined in nanometer accuracy. Specifically, a core-shell structured electrode material of MWCNTs@FePO4 was constructed, which showed promising potential as a cathode material for sodium ion battery as revealed by its high discharge capacity as well as the much improved rate capability.
