Exploration of Na(2.65)Ti(3.35)Fe(0.65)O9 as anode materials for Na-ion batteries

Chem Commun (Camb). 2015 Feb 21;51(15):3227-30. doi: 10.1039/c4cc09436k.

Abstract

Na(2.65)Ti(3.35)Fe(0.65)O9 rods were prepared by a simple solid-state route and coated with carbon to enhance their electronic conductivity. For the first time, Na(2.65)Ti(3.35)Fe(0.65)O9 was explored as an anode material for Na-ion batteries to deliver a discharge capacity of 137.5 mA h g(-1) at a current rate of 40 mA g(-1). The charge/discharge capacity of a carbon-coated sample increased by 46.3% to achieve 201.1 mA h g(-1).
