Betavoltaic Battery It Neither Requires Recharging Or Replacing
NDB belongs to a class of devices called betavoltaics. A device that generates charges using β-decay electrons as an energy source. Although emerging, the concept of betavoltaics itself is not new.
The original idea dates back to 1913 when Henry Moseley first invented the atomic battery using radium. The reason why it is emerging now is because of the recent advancements in nanotechnology. Where we can manipulate materials on an atomic level.
Although it generates charge and not store them. Most industries consider betavoltaics as a type of battery like any other in that it provides electricity. However, it is rather unusual because it neither requires recharging or replacing in a single user’s lifetime.
The extremely long radioactive half-life of isotope makes this happen. For this reason, betavoltaics is extremely promising as batteries for devices that are expected to last for a very long period of time (such as pacemakers). Or devices that are difficult to reach (such as space electronics).
Until now the betavoltaic battery was reserved for low power applications. So if you were to go and buy a nuclear battery. Only those that can power applications like pacemakers were possible. However, NDB and its integrated nanostructure can resolve this.
The Key Concept Here Is Power And Charge Storage.
To bring the betavoltaic battery to high power we need two things. One, more power and another is storage. By increasing the raw power of the betavoltaic it can achieve higher power. The integrated nanostructure allows this to happen.
Another is charge storage. Betavoltaics can generate charge non-stop for thousands of years. But without an appropriate storage system, the generated charge goes to waste. NDB uses ACNO-graphene supercapacitors.
A device which has a substantially longer device life and charge speed than traditional Li-ion batteries to store charge. Made from the Nobel-prize winning material graphene. This means that even for power-intensive applications there will be enough charge and power to support its use.
