Especially, the introduced surfactants served as a carbon source, bring a uniform carbon layer (about 2¡V8 nm) for heightening the electronic conductivity. The carbon coated TiO2 mesocrystals assembled from crystalline tiny subunits have more space sites for sodium-ion storage. When the material was applied as an electrode material in rechargeable sodium-ion batteries, it exhibited a superior capacity of about 90 mA h g?1 at 20 C (1 C = 168 mA g?1) and a highly reversible capacity for 5000 cycles, which is the longest cycle life reported for sodium storage in TiO2 electrodes. ? 2017 Elsevier B.V.Carbon coating layerElectrochemical propertyMesocrystalSodium-ion batteriesTiO2journal article10.1016/j.jpowsour.2017.05.0402-s2.0-85019876239https://www.scopus.com/inward/record.uri?eid=2-s2.0-85019876239&doi=10.1016%2fj.jpowsour.2017.05.040&partnerID=40&md5=6f431ead7cdd94b05af8cd00be97d911
