Summary: The evolution of smart life requires microscale energy storage devices with high power and energy density to integrate IoT devices with sustainable power generators. Pseudocapacitors are considered efficient energy storage devices due to their longer cyclability and high-power density compared to Li-ion batteries, but there are difficulties in patterning microscale electrodes using conventional methods. A one-step fabrication method of micro-supercapacitors was developed through the in situ formation of Co metals and reduced graphene oxides in a one-pot laser scribing process, resulting in a Co/rGO MSC with four times higher capacitance than rGO MSC.

Summary: As one of the effective methods for preparing nanomaterials, the template synthesis method allows for effective control of chemical reactions in the liquid or gas phase. Compared to other methods, nanomaterials prepared using this method exhibit various morphology and structure, resulting in excellent electrochemical performance. This review categorizes template methods into soft and hard templates, with the former offering flexibility and customization, and the latter providing precision and uniformity. However, soft templates lack precision and consistency, while hard templates restrict creativity and adaptability. The progress and prospect of template methods are also discussed.
