Unlike batteries, supercapacitors charge very quickly - but they also discharge
However, batteries with supercapacitorsalready used to a limited extent - for example, in Chinese public transport. But a bus equipped with such a battery must be charged at almost every stop.
In their work, the researchers proposed a new supercapacitor design that uses graphene laminate films with uniform spacing between layers.
The work showed that when the pores in the membranes exactly match the size of the electrolyte ions, the energy density increases radically—by about 10 times compared to conventional supercapacitors.
In addition, scientists note, new materialIt has a long service life, maintaining 97.8% of its energy intensity after 5,000 cycles of charging and discharging. The new supercapacitors are also very flexible - they can be bent up to 180 degrees.
Previouslywas reportedthat the new neural network will accelerate the development of moreenergy-intensive batteries for electric vehicles. This will be possible due to the fact that artificial intelligence can automatically evaluate the battery life - that is, it automates the process, which used to take from several months to several years.
