honeycomb‐lantern‐inspired 3d stretchable supercapacitors with enhanced specific areal capacitance

abstract
traditional stretchable supercapacitors, possessing a thin electrode and a 2d shape, have limited areal specific areal capacitance and are incompatible with 3d wearables. to overcome the limitations of 2d stretchable supercapacitors, it is highly desirable to develop 3d stretchable supercapacitors with higher mass loading and customizable shapes. in this work, a new 3d stretchable supercapacitor inspired by a honeycomb lantern based on an expandable honeycomb composite electrode composed of polypyrrole/black‐phosphorous oxide electrodeposited on carbon nanotube film is reported. the 3d stretchable supercapacitors possessing device‐thickness‐independent ion‐transport path and stretchability can be crafted into customizable device thickness for enhancing the specific areal energy storage and integrability with wearables. notably, a 1.0 cm thick rectangular‐shaped supercapacitor shows enhanced specific areal capacitance of 7.34 f cm−2, which is about 60 times higher than that of the original 2d supercapacitor (120 mf cm−2) at a similar discharge rate. the 3d supercapacitor can also maintain a capacitance ratio of 95% even under the reversible strain of 2000% after 10 000 stretch‐and‐release cycles, superior to state‐of‐the‐art stretchable supercapacitors. the enhanced specific areal energy storage and the customizability in shapes of the 3d stretchable supercapacitors show immense promise in a wide range of applications in stretchable and wearable electronics.

editable supercapacitors with customizable stretchability based on mechanically strengthened ultralong mno2 nanowire composite

abstract：although some progress has been made on stretchable supercapacitors, traditional stretchable supercapacitors fabricated by predesigning structured electrodes for device assembling still lack the device-level editability and programmability. to adapt to wearable electronics with arbitrary configurations, it is highly desirable to develop editable supercapacitors that can be directly transferred into desirable shapes and stretchability. in this work, editable supercapacitors for customizable shapes and stretchability using electrodes based on mechanically strengthened ultralong mno2 nanowire composites are developed. a supercapacitor edited with honeycomb-like structure shows a specific capacitance of 227.2 mf cm−2 and can be stretched up to 500% without degradation of electrochemical performance, which is superior to most of the state-of-the-art stretchable supercapacitors. in addition, it maintains nearly 98% of the initial capacitance after 10 000 stretch-and-release cycles under 400% tensile strain. as a representative of concept for system integration, the editable supercapacitors are integrated with a strain sensor, and the system exhibits a stable sensing performance even under arm swing. being highly stretchable, easily programmable, as well as connectable in series and parallel, an editable supercapacitor with customizable stretchability is promising to produce stylish energy storage devices to power various portable, stretchable, and wearable devices.
