Supercapacitors, which have safe and fast charge (in seconds) and high energy storage are promising for consumer electronics, hybrid electric vehicles and industrial power management. Recently, laser scribed graphene has been increasingly studied for supercapacitor applications. With the laser scribing process, graphene can be directly fabricated and patterned for supercapacitors. Researchers in China summarize recent developments, current challenges and future advancements of supercapacitors based on laser scribed graphene. They summarize facile laser scribing methods for graphene and the application for electrochemical double-layer capacitors, pseudo-capacitors, and hybrid supercapacitors. Recent developments are discussed demonstrating that laser scribing technology can simply induce graphene and simultaneously pattern graphene electrodes for supercapacitors. According to the researchers the easy and cost-effective fabrication method demonstrates great potential for commercial supercapacitor applications. Other featured supercapacitors are also reviewed…read more. TECHNICAL ARTICLE
