Can polymer materials be used for flexible energy storage devices?

Then the design requirements and specific applications of polymer materials as electrodes, electrolytes, separators, and packaging layers of flexible energy storage devices are systematically discussed with an emphasis on the material design and device performance.

Do flexible energy storage devices have high energy density?

Although Li-ion fiber batteries with a high energy density of 80 Wh kg−1had been achieved , the energy density of flexible energy storage devices lags far behind conventional LIBs (∼250 Wh kg−1), which is the stumbling block on the path of their practical applications.

What makes a flexible ESD wearable?

One of the ultimate goals for a flexible ESD is to make it wearable with textile-level texture and comfortability. 6 Comfortability of a flexible ESD has almost never been discussed in the literature. Referring to the comfortability evaluation of textile, we believe that a truly wearable ESD should be both flexible and soft.

Are flexible energy storage devices based on different energy storage mechanisms?

A variety of flexible energy storage devices have been reported based on different energy storage mechanisms. Flexible supercapacitors with high power density and simple configuration are first designed but they suffer from low energy densities.

Why is natural leather a good material for thermal camouflage armor?

Wang et al. directly edited the natural leather structure for obtaining multifunctional thermal camouflage armor by in situ growth of SiO 2 nanoparticles. [ 21] The special porous fiber structure and rough surface also endow the leather with good hydrophobicity and mechanical properties. [ 22]

Are flexible energy storage devices the future of wearable electronics?

Abstract Flexible energy storage devices have received much attention owing to their promising applications in rising wearable electronics.
