Olivine structured lithium iron phosphate, LiFePO4 (LFP), is a promising alternative cathode material due to its high theoretical capacity (170 mA h g(-1)), low cost and higher environmental compatibility. However, due to its poor electronic conductivity and Li+-ion diffusivity the electrochemical performance of LFP deteriorates with increasing charge/discharge rates. Networking of downsized LFP particles with an improperly chosen carbon conduit may not effectively reduce the Li+-ion diffusion pathways and improve electron transport. We demonstrate here a unique 3D configuration comprising ultra-small LFP particles (size: 5 +/- 2 nm) "adhered" to few-layer reduced holey-graphene oxide sheets (h-GO) that allows Li+-ions to traverse shorter non-tortuous pathways. The h-GO sheets, which are only
