Recent advances in energy storage systems have speeded up the development of new technologies such as electric vehicles and renewable energy systems. In this respect, supercapacitors have gained interest due to their unique features such as high power density, long lifespan, and wide operating range.
The increasing demand for efficient, portable, and eco-friendly energy storage solutions is driving the development of supercapacitors and batteries with high energy and power densities.
Conventional supercapacitors and batteries often cannot be easily integrated into emerging technologies such as smart textiles, electronic magazines, e-books, packages with data-collection capabilities, flexible wearable electronics and displays, flexible solar cells, epidermal sensors, and others.
The enhanced charge storage of the modified surface will be reinforced by the strong connection between the active surface and the intact substrate, enabling efficient charge transfer and maximizing capacitance. Pulsed nanomaterials via laser carbonization show potential as supercapacitor electrodes.
