The control of energy storage and release in micro energy devices is important and challengeable for utilization of energy. In this work, three kinds of micro energy storage devices were fabricated through in situ integrating different aluminum/molybdenum trioxide (Al/MoO3) nanolaminates on a semiconductor bridge. The morphology and composition characterizations confirm that Al layer and MoO3 layer closely contacted with different single thickness, endowing the Al/MoO3 nanolaminates with variable heat release from 466.3 J/g to 613.0 J/g. Meanwhile, these devices demonstrate controllable energy release ability showing the flame durations of 60-600 mu s (discharged with 47 mu F/50 V) by simply changing the Al and MoO3 accumulate structure in Al/MoO3 nanolaminates. Preliminary reaction mechanism obtained by probing the reaction in argon and vacuum atmosphere suggests that condensed state reaction process was confirmed in these nano multilayered films. This result may yield significant advantages in developing a tailored architecture for micro ignition applications.
