Editable supercapacitors with customizable stretchability based on mechanically strengthened ultralong MnO2 nanowire composite

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 configurati...
