Dip-spin coating of reticulated vitreous carbon with composite materials to act as an electrode for 3D microstructured lithium ion batteries

► A technique for coating 3D substrates in layers of composite electrode material is presented. ► Uniform layers containing LiFePO4, LiMn2O4 and TiO2 have been deposited on carbon foams. ► Samples with a high area specific capacities (>1000 μA h cm−2) have been prepared. ► High rate performance (∼50% DOD at 25 C) was also observed for the same sample.
