Nanotechnology helps the battery pack charge fast but lasts a long time

US scientists have found that lithium-ion batteries or nickel metal hydride batteries are often degraded during operation as they are charged and discharged quickly. Meanwhile, the manufacture of the active substance in the battery in the form of a thin film allows the battery to charge and discharge rapidly, but the stored amount of electricity is almost zero because the material has no place to store energy.

For that reason, Professor Paul Braun and colleagues at the University of Illinois have studied the development of three-dimensional nanostructure for battery terminals, allowing it to charge and discharge rapidly without wasting energy. . They fold the thin film into a three-dimensional structure that meets both requirements for high capacitance and electrical current. Tests show that the battery's electrodes can be charged or discharged in just seconds, which is 10-100 times faster than the similar sized electrodes used in today's batteries.

In addition to consumer electronic devices that charge fast, batteries are more energy-efficient, quick to charge, and last longer, as are electric vehicles, medical equipment and military equipment.
