Chinese startup Betavolt recently made a discovery that has the potential to change the charging model of our smartphones. It is a new type of battery, which, according to the company, will have autonomy for several years.
With an estimated autonomy of up to 50 years, charging your smartphone will no longer be a worry. It is a solution that will solve one of the main daily concerns of those who use this type of device.
The atomic battery promises autonomy for up to 50 years
One detail that may make you uncomfortable is the fact that it is an atomic battery. Although Petavolt defends the safety of its discovery, concerns about the consequences of the radiation generated are legitimate.
“The atomic energy battery developed by Petavolt is completely safe, does not contain any external radiation, and is suitable for use in medical devices such as pacemakers, artificial hearts and cochleae in the human body.”
The Chinese company reveals that the multi-layer design of these batteries prevents them from burning and exploding under sudden force. Moreover, it will withstand extreme temperatures (from -60°C to 120°C).
The batteries provided by the Chinese startup provide 100 microwatts of power at 3 volts. However, the company plans to make a leap in its technology that will allow the power of these batteries to increase to 1 watt in 2025.
Betavolt's goal is to have this technology mass-produced and turned into marketable products. Equipment such as smartphones and drones are among the candidates for this new type of battery.
Taking into account the typical useful life of these technology products, we can say that charging them will not be a concern. For a smartphone, this could be considered overkill.
How do these atomic batteries work?
Atomic batteries work by converting the heat generated by radioactive decay into energy. Isotopes such as plutonium-238 are usually used, which are known for their long autonomy and unnecessary maintenance.
Naturally, the use of radioactive materials raises safety concerns for human health and the environment. However, Betavolt is confident in the safety of its product.
“Atomic energy batteries are environmentally friendly. After a period of decay, the 63 isotopes transform into a stable isotope of copper, which is not radioactive and does not pose any threat or pollution to the environment.”
At the moment, there is no indication when this solution may become available in the market. Their promise is very tempting, but vigorous action will be needed to raise awareness about the safety of these batteries.
