Materials engineers at Monash University in Australia have devised a method of producing graphene supercapacitors that have the same energy density as the lead-acid battery under your car's hood. Not ...

Indian researchers have developed a high-voltage supercapacitor that could improve the performance of electric vehicles and support broader renewable energy applications. The device was created by ...

Graphene supercapacitors are moving from lab curiosity to serious contender for the next wave of electric vehicle energy storage. By pairing the near-instant charging of capacitors with the high ...

Conventional electrolytes used in commercial supercapacitors can operate between 2.5–3.0 V and begin to decompose or face safety issues (such as flammability) at higher voltages.
