With an ever more connected society where technological products are increasingly taking up a place in our daily lives, batteries are a real challenge for the future.
Many scientists are trying to develop more energy-efficient solutions while being less polluting or more sustainable.
This is particularly the case of the Californian company NDB, specialist in green energy, which presented a concept of battery powered by radioactive nanodiamonds, reports ETX Studio.
This battery concept is doubly interesting since it would be able to withstand a large number of recharging cycles, while being able to self-recharge.
According to the startup behind the concept, the battery has a lifespan of nearly 28,000 years and has an energy density 57,000 times that of lithium batteries.
It would therefore be a particularly interesting alternative compared to current models.
A more sustainable solution
Furthermore, the radioactive nanodiamond battery could be an optimal solution, because beyond its performance in terms of autonomy, it would also be a more sustainable alternative.
In addition to being particularly resistant, it would also make it possible to recycle part of the nuclear waste since radioactive nanodiamonds are created from them, as the NDB video explains.
Coupled with an integrated circuit, these components would allow the battery to self-recharge for several thousand years.
But all these beautiful promises are above all theoretical estimates.
In fact, the autonomy of radioactive nanodiamond batteries could last much less than 28,000 years.
However, the concept would have many advantages over current batteries.
It could indeed be a less polluting and more durable alternative which could still last ten years without having to be recharged.
Ultimately, radioactive nanodiamond batteries - the radiation is lower than that of the human body - could end up in our smartphones and other connected devices, but also in electric and autonomous cars.
The first tests carried out at the Lawrence Livermore National Laboratory and at the University of Cambridge are in any case promising.
