A Sn thin film composed of numerous continuous Sn particles (ranging from 25 to 200nm) was prepared on a copper foil via magnetron sputtering. Electrochemical properties of the Sn thin film, as anode electrode in lithium ion batteries, were studied by conventional charge/discharge tests and cyclic voltammograms. The as-prepared Sn electrode showed high initial discharge capacity of 908 mAh g −1...
Surface nitridation of the Li4Ti5O12 particles was carried out by thermal treatment with urea as the nitrogen source in a controllable manner. The titanium nitride (TiN) was formed in the well-dispersed zones on the surface of the Li4Ti5O12 particles, depending on the coverage of the nitride. The surface TiN formed led to a great improvement of the conductivity of the oxide. The extent of the surface...
