These properties are important for shorter distance in ion/electron movement and better electrode surface/electrolyte contact for energy storage applications. Here nanostructured FePO4 cathode materials were synthesized by using peptide nanostructures as a template inspired by biomineralization process. The amorphous, high surface area FePO4 nanostructures were utilized as a cathode for lithium-ion batteries. Discharge capacity of 155 mAh/g was achieved at C/20 current rate. The superior properties of biotemplated and nanostructured amorphous FePO4 are shown compared to template-free crystalline FePO4.EnglishHydrogelNanobeltNanofiberPeptide amphiphileSelf-assemblyTemplate-directed materialsBiomineralizationCathodesCrystalline materialsElectric batteriesElectrodesHydrogelsIonsLithium alloysLithium compoundsNanobeltsNanofibersNanostructuresPeptidesSelf assemblyStabilityBiomineralization processDischarge capacitiesElectrode surfacesEnergy storage applicationsLithium-ion battery cathodesPeptide amphiphilesStructural stabilitiesTemplate-directed synthesisLithium-ion batteriesArticle10.1021/acsami.6b02528
