文摘

A green facile scalable method inspired by polymeric dental restorative composite is developed to synthesize TiO₂/carbon nanocomposites for manipulation of the intercalation potential of TiO₂ as lithium-ion battery anode. Poorly crystallized TiO₂ nanoparticles with average sizes of 4鈭? nm are homogeneously embedded in carbon matrix with the TiO₂ mass content varied between 28 and 65%. Characteristic discharge/charge plateaus of TiO₂ are significantly diminished and voltage continues to change along with proceeding discharge/charge process. The tap density, gravimetric and volumetric capacities, and cyclic and rate performance of the TiO₂/C composites are effectively improved.
