Graphene materials may increase the energy storage capacity of capacitors

Engineers at the University of California, San Diego, have discovered a way
to increase graphene's ability to store electricity.
The research is expected to provide better support
for improving the energy storage capacity of capacitors used in automobiles, wind turbines, and solar cells.

The capacitor charge and discharge speed is fast, which is more useful for fields with fast energy and large mutations, and the ability to charge and discharge quickly is a clear advantage
compared to the long charging time of the battery.
The problem with capacitors, however, is that they store less
energy than batteries.
How to increase the energy storage capacity of capacitors? Prabhakar Bandaru, a professor of mechanical engineering in the Department of Engineering at the University of California, San Diego, used graphene as a test model material to introduce more charge
into the capacitor electrodes.
In principle, it increases the charge, resulting in an increase in capacitance, thereby increasing energy storage
