How can flexible energy storage improve wearable electronics?

Addressing the escalating energy demands of wearable electronics can be directly approached by enhancing the volumetric capacity of flexible energy storage devices, thereby increasing their energy and power densities.

What are flexible energy storage devices?

To date, numerous flexible energy storage devices have rapidly emerged, including flexible lithium-ion batteries (LIBs), sodium-ion batteries (SIBs), lithium-O 2 batteries. In Figure 7E,F, a Fe 1−x S@PCNWs/rGO hybrid paper was also fabricated by vacuum filtration, which displays superior flexibility and mechanical properties.

Can ultraflexible energy harvesters and energy storage devices be integrated?

Integrating ultraflexible energy harvesters and energy storage devices to form an autonomous, efficient, and mechanically compliant power system remains a significant challenge.

What is the mechanical reliability of flexible energy storage devices?

As usual, the mechanical reliability of flexible energy storage devices includes electrical performance retention and deformation endurance. As a flexible electrode, it should possess favorable mechanical strength and large specific capacity. And the electrodes need to preserve efficient ionic and electronic conductivity during cycling.

Can wearable energy-storing textiles withstand harsh deformation?

As for wearable energy-storing textiles, it can withstand harsh deformation. Five yarn SCs were connected in series and were woven into a piece of fabric together with common cotton yarns. This soft energy-storing fabric can light a red light-emitting diode (LED).
