China has created a safe nuclear battery with a life span of 50 years

< IMG SRC = "/Uploads/Blogs/EA/99/IB-FQV36TT6i_e92958d4.jpg" Alt = "in China created a safe nuclear battery with a life span of 50 years"/> ~ ~ ~ ~ < P > Scientists at the Northwestern Pedagogical University in Lanchzhou (Gansu Province) presented a nuclear battery created on the basis of carbon-14 (& sup1; ⁴c). The device can work smoothly for 50 years without loss of output voltage and is intended to power cardiostimulants, spacecraft and devices operating in extreme conditions.

< P > This battery is the first development of this type in China and can dramatically change the scope of autonomous power in the country. Earlier, China depended on carbon-14 imports from Canada, South Africa, Australia and Russia. However, last year, scientists established their own production of isotope on a local reactor, which allowed to reduce the cost of its purchase.

< p >The maximum battery power reaches 433 microvides. During radioactive decay & sup1; ⁴c electrons and positrons are formed, and electrons, catching semiconductor transitions at the border with radioactive material, generate electric current.

~ ~ > < p > carbon-14 is widely used in radiocarbon dating, and its half-life is 5730 years. The calculations show that the battery will lose only 5% of the power for 50 years, and its potential service life can exceed 100 years. This makes it an ideal energy source for autonomous systems, including in space missions.

< P > During the tests, the battery worked steadily at temperatures from -100 & Deg; C to 200 & Deg; C and for four months continuously ensured the operation of the LED lamp. It was attended by Beita Pharmatech specialists, who uses & sup1; ⁴c for medical and scientific purposes. Scientists plan to create a robotic line for batch production of such batteries.

< P > Carbon-14 isotope is considered relatively safe for humans, and batteries can be powered by implants and cardiostimulants throughout life, which significantly exceeds modern analogues with a resource of 15 years. Chinese researchers & ndash; not the only ones working in this direction: at the end of 2024 with & Rsquo; reports of a similar project in the UK.
