Herein, we demonstrate a facile approach to fabricate a cathode material of LiFePO4 with nitrogen-doped carbon layers by applying egg white as both carbon source and nitrogen sources. The nitrogen doped carbon layers are in situ coated on the LiFePO4 particles, which effectively improves the electrical conductivity of rapid Li-ion diffusion. When evaluated as a cathode material for lithium ion batteries (LIBs), LiFePO4 material with nitrogen doped carbon shows high capacities of 164 mA h g(-1) at 0.1 C, 144 mA h g(-1) at 1 C and 120 mA h g(-1) at 5 C. The result implies that such novel LiFePO4 material is a potential cathode material for LIBs. (C) 2020 The Society of Powder Technology Japan. Published by Elsevier B.V.
