High-performance microsupercapacitors (MSCs) with three-dimensional (3D) structure provide an effective approach to improve the ability of energy storage. Because electrodes 3D are generally easily destroyed under mechanical deformation in practical applications, we fabricated a self-healable MSC consisting MXene (Ti3C2T x)-graphene (reduced graphene oxide, rGO) composite aerogel electrode by wrapping it self-healing polyurethane as outer shell. The MXene-rGO combining large specific surface...
In large-scale applications of portable and wearable electronic devices, high-performance supercapacitors are important energy supply sources. However, since the reliability stability generally destroyed by mechanical deformation damage during practical applications, stretchability self-healability must be exploited for supercapacitors. Preparing highly stretchable self-healable electrodes is still a challenge. Here, we report reduced graphene oxide fiber based springs as The (diameters 295...

Restricted by their energy storage mechanism, current devices have certain drawbacks, such as low power density for batteries and supercapacitors. Fortunately, the nearest ion capacitors, lithium-ion sodium-ion capacitors containing battery-type capacitor-type electrodes, may allow achieving both high densities.

Abstract The rapid development of smart wearable and integrated electronic products has urgently increased the requirement for high‐performance microbatteries.

In order to overcome these a low quasi‐solid‐state aqueous...
