High-capacity cathodes for lithium-ion batteries from nanostructured LiFePO4 synthesized by highly-flexible and scalable flame spray pyrolysis

► Nanosized FePO4⋅xH2O was synthesized using highly scalable flame spray pyrolysis. ► High purity Nano-LiFePO4/C composite was produced by a subsequent solid-state reaction. ► Material consists of LiFePO4 NPs homogeneously distributed in a carbon matrix. ► Material has a good discharge capacity of more than 140 mAh g−1. ► Very high drain rates of 16 C while delivering 40 mAh g−1 are shown without degradation.
