Ion beam modification to effect ion beam mixing without changing morphology was investigated as a means to improve the electrochemical performance of Ge thin film electrodes for rechargeable Li batteries. As a result of a minimum tenfold increase in the strength of adhesion of the Ge film to the current collector (substrate), the ion beam-mixed electrodes exhibited stable specific capacities of ∼1500 mAh g -1 (close to the theoretical maximum of 1623 mAh g -1) for galvanostatic cycling rates of...[Show more]
