ABSTRACT
In recent years, research in graphene supercapacitors has accelerated and its performances have seen decent improvements both in energy and power densities, mostly due to the addition of pseudocapacitive elements. On top of that, new fabrication techniques such as direct laser writing have gotten a lot of attention due to its low-cost, flexibility and widespread availability. Supercapacitors are energy storage devices with ideal characteristics to complement traditional batteries, such as a high power density and long cyclability, which batteries lack. Microsupercapacitors, where both electrodes are situated in the same plane, can be fabricated on flexible substrates to enable new applications in flexible electronics or wearables.
