Abstract：
Miniaturized energy storage devices are essential to power the growing number and variety of microelectronic technologies. Here, a concept of self-propelled microscale energy storage elements that can move, reach, and power electronic circuits is reported. Microrockets consisting of a nickel sulfide (NiS) outer layer and a Pt inner layer are prepared by template-assisted electrodeposition, and designed to store energy through NiS-mediated redox reactions and propel via the Pt-catalyzed decomposition of H2 O2 fuel. Scanning electrochemical microscopy allows visualizing and studying the energy storage ability of a single microrocket, revealing its pseudocapacitive nature. This proves the great potential of such technique in the field of micro/nanomotors. On-demand delivery of energy storage units to electronic circuits has been demonstrated by releasing microrockets on an interdigitated array electrode as an example of electronic circuit. Owing to their self-propulsion ability, they reach the active area of the electrode and, in principle, power its functions. These autonomously moving energy storage devices will be employed for next-generation electronics to store and deliver energy in previously inaccessible locations.
