Energy storage sheet metal design

What are stretchable energy storage devices (sesds)?

Stretchable energy storage devices (SESDs) are indispensable as power a supply for next-generation independent wearable systems owing to their conformity when applied on complex surfaces and functionality under mechanical deformation.

Which materials are used in SESD batteries?

A flexible and stretchable fiber-shaped Li-air, [ 78] Zn-air, [ 74] and Al-air [ 79] battery was reported with Li, Zn, and Al spring as anode, respectively. With intrinsic stretchability, environmental compatibility, high capacities, and high electrical conductivity, conducting polymer-based materials are extensively explored in SESDs.

Why is graphene used in sesds?

Graphene is also attractive in SESDs owing to their high mobility and elasticity. For example, a stretchable current collector rGO/PDMS was prepared by immersing 3D porous PDMS sponge into graphene oxide (GO) solution, followed by reducing GO into rGO with enhanced electrical conductivity, as illustrated in Figure 6b. [ 63]

Why is graphene fiber a good material for electrolyte penetration?

The core graphene fiber exhibited a low density of 0.23 g cm −3 while maintaining good mechanical strength and high electrical conductivity. The sheath graphene framework provided high surface area for electrolyte penetration.

How is the stretchable cathode AgNW/PDMS prepared?

The stretchable cathode AgNW/PDMS was prepared through a lithographic filtration method. It could deliver an areal capacity of 0.27 mAh cm −2 and maintain stable after 1000 charge/discharge cycles at a strain of 80%. The stretchable anode was fabricated by electroplating Zn onto AgNW/PDMS.
