Electrochemical Synthesis of Potassium Titanate Nanowires in Molten Salts with Good Li+-Intercalation Performance

The novel material K1.35Ti8O16@C was successfully fabricated via an effective, controllable, and cost-effective electrochemical synthetic method and further evaluated as an anode material for lithium-ion batteries (LIBs). This material delivered high reversible capacities of ∼320 mAh g−1 at 50 mA g−1 and excellent long-term cycle stability (135 mAh g−1 after 2000 cycles at 1 A g−1) owing to the high electronic conductivity and fast reversible electrochemical Li-intercalation/extraction behavior of the nanowire structure of K1.35Ti8O16.
