Batteries seem to be the limiting factor in the popularity of electric cars. They are one of the most expensive components of the vehicle, and have limited range compared with gasoline powered ...
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 ...
Consider an electric vehicle that takes only a few seconds to recharge while braking and then using that energy to power up the vehicle until the next stop. Imagine a lightweight smartphone that, ...
A team of South Korean scientists has developed a new graphene supercapacitor that can store almost as much energy as a lithium-ion battery, but charge in only 16 seconds. This makes it an ideal ...
A breakthrough in supercapacitor performance has been achieved with the development of a device that can store as much energy as a battery while recharging in seconds. The graphene-based ...
Theoretical analysis using an analytical equivalent circuit model shows that the enhancement of the areal capacitance is up to 300 times for Hilbert BFE electrodes compared to its planar electrode ...
• London Graphene is developing a new type of charger for the business traveller, based on graphene supercapacitors. • In 2013 London Graphene took an option to license two patents developed at the ...
Batteries are terrible. Compared to many other methods of storing energy, especially fossil fuels, batteries aren’t very energy dense—that is, a 1-pound battery stores far less energy than is ...
Like an electrochemical battery, a capacitor is used to store energy. Some electrochemical batteries can indeed be relatively efficient; however, charge time is still their primary limiting factor for ...
