Improvement of a novel anode material TeO2 by chlorine doping
A simple and versatile method for the preparation of chlorine-doped TeO2 was developed via thermal decomposition of Te6O11Cl2 in situ. Te6O11Cl2 was prepared with TeCl4 and ethanol as reagents, while TeO2 was fabricated with water as a solvent. The morphology, surface, and electrochemical performances of the obtained materials were systematically studied. It was found that chlorine-doped TeO2 demonstrated the highest cycling efficiency and stability than Te6O11Cl2 and TeO2. The presence of Te–Cl bond is expected to contribute to the reversible capacity and Li inserting process.
