Prospects of micro-nano energy storage devices

Are nanomaterials the future of energy storage?

Nanomaterials are the answer to all the modern-day requirements for compact energy storage devices. The need for new-age energy storage devices includes solar panels, wind power generators, and other wide varieties of materials.

Why is nano structure important for energy storage devices?

Nano structuring electrodes improves conductivity, and stability. These advances enable more powerful, durable, and sustainable energy storage devices. The development of next generation energy storage devices with low self-discharge rate, high energy density and low cost are the requirements to meet the future and environmental needs.

Which nanomaterials are used in energy storage microdevices?

Only a few of them like graphene, SWCNTs, MWCNTs, and silicon nanoparticles are being actually used in devices. A variety of 2D and 3D nanomaterials have been synthesized and used for energy storage microdevices for compact power sources.

Can nano-device-based energy storage be used as a micro-battery/capacitor?

Recent research on nano-device-based energy storage has helped to clarify its mechanisms. Simultaneously, the development of portable and embedded micro devices has advanced, increasing the application potential for nano-devices as micro-batteries/capacitors for energy storage. This demand has accelerated the development of miniature energy storage devices.

Are on-chip micro/nano devices useful in energy conversion and storage?

On-chip micro/nano devices haven’t been widely applied in the field of energy conversion and storage despite their potential. This may be attributed to the complex configurations of energy devices and the immature theoretical models.

What are smart energy storage devices?

Smart energy storage devices, which can deliver extra functions under external stimuli beyond energy storage, enable a wide range of applications. In particular, electrochromic (130), photoresponsive (131), self-healing (132), thermally responsive supercapacitors and batteries have been demonstrated.
