Historically, the energy storage industry has often relied on policy support and fiscal subsidies. It lacked sustainable ...

Supercapacitors possess a high cycle efficiency (more than a million cycles), a large number of charging cycles higher than 95%, and a faster discharge time with a longer life. The high value of a ...

Supercapacitors—also known as ultracapacitors—store energy similarly to batteries. However, they dispense power extremely quickly instead of over hours. As high-power-density energy storage systems, ...

Scientists have set themselves the goal of improving these ubiquitous, fast storage devices by developing a new kind of electrode based on graphene. Supercapacitors are the nimble little siblings of ...

Researchers at the Indian Institute of Science (IISc) Department of Instrumentation and Applied Physics (IAP) and associates created a new supercapacitor that can be charged by shining light on it.
