Russian expert: The "nuclear battery" that China has started mass production of was invented by Russia!
A Russian netizen named Andrei expressed regret: the advanced research we led in will have to be purchased from China.
On April 5, the "Komsomolskaya Pravda" of Russia published an expert article.
A Chinese company announced the continuous production of nuclear batteries with a voltage of 3V and 100μW.
It is reported that the durability of the atomic battery is about 50 years. Its size is 15*15*5 millimeters, and the working temperature range is from -60 to +120 degrees.
Meanwhile, from the perspective of radioactivity, the power supply is safe: the half-life of nickel-63 is 100 years, and it decomposes into stable isotopes of copper.
Russian experts said: However, just a few years ago, this technology belonged to the Russians.
It is reported that Professor Mephi conducted experimental design work for the "nuclear battery" project in 2023. This physicist said, "As a result, a prototype of an autonomous radioactive isotope source based on narrow-area semiconductor materials was created."
However, experts pointed out that nickel-63 was the key obstacle to introducing this technology, as the price of 100 grams of nickel-63 exceeded 200 million rubles at that time.
This means that the cost of the battery was extremely expensive, thus hindering Russia's progress.
