Thin‐film anodes for Li‐ion batteries prepared by using electrostatic spray deposition are reported. They consist of a tin‐based amorphous oxide composite with a porous, spherical, multideck‐cage morphology (see figure). The electrochemical properties of the thin‐film electrodes are shown to be improved significantly by introducing Li 2 O and CuO, the ternary Li 2 O–CuO–SnO 2 electrode being demonstrated to exhibit the best performance.
