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.
Two-dimensional materials such as layered transition-metal dichalcogenides, carbides, nitrides, oxides and graphene-based materials have enabled very thin active electrodes with high energy density and excellent cyclability for flexible energy-storage devices.
However, advances in power modules have lagged far behind the tissue-integrated sensor nodes and circuit units. Here, we report a soft implantable power system that monolithically integrates wireless energy transmission and storage modules.
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.
Fibre-like energy-storage devices can be achieved using coaxial or twisted fibres to enable flexibility and stretchability. An intrinsically stretchable device differs from the other types by using individual stretchable components, which offers the greatest manufacturing compatibility.
