Russian scientists from the National Research Technological University “MISiS” under the leadership of Professor of the Department of Semiconductor Electronics and Semiconductor Physics Viktor Murashov have developed an innovative autonomous power source – a compact atomic battery that can work up to 20 years.

The novelty is based on an original, patented microchannel 3D structure of a nickel beta-voltaic element. Thanks to this solution, the radioactive element is applied on both sides of the so-called planar pn junction, which makes it possible to simplify the cell manufacturing technology, as well as to control the reverse current “stealing” the battery power.

The special microchannel structure provides an increase in the effective conversion area of ​​beta radiation by 14 times, which results in an overall increase in current. Due to innovative solutions, the size of the battery has been reduced by 3 times, at the same time, the specific power has increased by 10 times, and the cost price has decreased by 50%.

And yesterday Samsung unveiled a long-lasting smartphone with a 7000 mAh battery.
