Miniaturization on Chip Nano Energy Application

The recent trends and increasing demand to manufacture portable, low-weight and wearable electronics have greatly prompted researchers to design miniaturized energy storage devices (MESDs). Arranging bigger things in the nanoscale can unlock unique characteristics and enhance the features. A combination of electrochemically active nanomaterials and microelectronics systems permits the formation of novel MESDs. Hence, on one hand, numerous efforts need to be put into synthesizing nanomaterials with efficient energy conversion properties. On the other hand, advanced microelectronic techniques to design MESDs are aspired to deliver high power density and energy density with a longer lifecycle. In this chapter, we discuss the latest trends and progress approached to design planar microstorage devices on chip and various nanostructured electrode materials. The performance of different energy storage devices with respect to their storage techniques, such as EDLC and pseudocapacitive material based on carbon nanotubes (CNTs), graphene, transition metal oxides (TMOs), transition metal hydroxides (TMHs), and transition metal dichalcogenides (TMDs) critically analyzed, which would encourage the researchers to contribute to the progress of electrochemically active nanomaterials and miniaturized electronic devices. And finally, the advantages, disadvantages, technical challenges, and viewpoints for MESD configuration summarized could draw out beneficial suggestions for future study and prospective for designing MESDs for practical application.
