Single　crystalline　lithium　titanium　phosphate　(LiTi2(PO4)(3),　LTP)　nanowires　of　variable　diameters　with　smooth　or　porous　surface　are　obtained　by　a　sol-gel　method　combined　with　a　polycarbonate　porous　membrane　template.　The　obtained　LTP　nanowires　are　uniform　in　shape　and　with　diameters　depending　on　template　pore　sizes.　The　single　crystalline　nature　of　LTP　nanowires　are　confirmed　by　transmission　electron　microscopy　(TEM)　images　and　electron　diffraction　(ED)　patterns.　The　porosity　of　LTP　nanowires　could　be　tuned　by　adjusting　the　ratio　of　citric　acid　to　titanium　in　precursor　solution.　The　LTP　nanowire　array　fabricated　on　a　platinum　foil　are　tested　as　a　lithium　ion　battery　electrode　for　electrochemical　properties,　proving　such　nanostructure　would　allow　high　rate　capacity　as　well　as　capacity　retention　without　carbon　coating.　(C)　2018　Elsevier　Ltd.　All　rights　reserved.
