American researchers create a postage stamp-sized nanoaccumulator

It is no secret that each new generation of electronic devices is much smaller in size compared to their predecessors. Naturally, power supplies are also getting smaller. In the near future, we will probably witness the birth of nanoaccumulators - ultra-miniature power supplies.

Researchers at the University of Maryland have developed a tiny postage stamp-sized battery made up of millions of nano-batteries.

The base of the power source is made of a special ceramic material, permeated with millions of microscopic pores. Each pore is equal to one eighty thousandth the thickness of a human hair. The pores are filled with electrolyte, and nanotubes are used as electrodes. These electric "honeycombs" are connected in parallel, are synchronously charged and retain the electric charge until the required moment.

Charging time does not exceed 10 minutes. The battery life of the baby is calculated in many thousands of cycles without sacrificing its performance, which is far superior to the currently used lithium-ion batteries.

The current version of the nanoaccumulator is designed more as a proof of concept. However, scientists have confirmed that in the next version, the density of stored energy can be increased by at least 10 times. Researchers are also working on methods of industrial production of nanoaccumulators in order to launch them on the market.
