Longest Battery Life for Laptops

By | January 8th, 2009



Meet the new revolutionary battery known as Beta-voltaic Battery.You probably have heard of it, but never know how it is possible to provide power for 30 years without recharge. We’ll explain the functionality of these batteries in simple words:

  • Expected battery life (without charging): 30 years
  • Expected release date: 2011

From where the energy comes, for that long time:

It comes from radioactive decay of a radioactive substance. This decay time can be either in nanoseconds (a very small fraction of second) or it can be thousands of years! (Depending on the substance and its quantity)

What is radioactive substance?

A matter that vanishes (literally) over a period of time by converting into energy and releasing that energy into surroundings is called radioactive substance. A 1Kg of substance can reduce into 0.5Kg after 1 hour if the Half-Life (a notation for time used by scientist) of that substance is 1 hour.

How it Works?

Bottom line:
To make it simple, we can make an analogy with solar (photovoltaic) cells:

  • In solar cells the power comes from sun which (looks till now) will last for a very long time. In betavoltaic cells the energy comes from a decaying radioactive material (which can last for a long time).
  • In solar cells, the sun light (photons) hit on panels to produce current, similar to that, in betavoltaic cell the beta particles coming from radioactive substance hits the plate (of p-n junction) to produce current.

But we know that the current produce by solar cell is very small, compare to that the current produce by betavoltaic cell is even lesser.

How to magnify the current:

As more than half of the Beta particles misses the plates, just like sun rays missing the solar panel, they have come up with the idea to use the collecting surfaces with deep pits. Each of the pit will have the radioactive substance in it hence  the maximum beta particles will hit the walls inside the pit

These holes are 40 times deeper than their width, just like a deep well. Imagine a sun dropped into a huge well, maximum of the rays would strike the walls. This technology increases the current many folds. The engineers are working to further magnify the current to power devices like laptops.

The life of the battery is equal to the life of the decaying radioactive material!

Environment Friendly:

These batteries claim to be environment friendly with no toxic or hazardous affect. You can throw them away when their life is over!

    Unbelievable!

    for now :P

  • Roberto

    How much will it cost !!!!???? :-O ….

    Yet there hasn’t been any official announcement about the price, However I’m sure it will be affordable to compete in the market. I think it will be a standard battery for laptop 5 years from now! Hence it will become cheap.

    What about radioactive poisoning? —-
    The effect on human body cells. —- That said, What is the amount of power compared to conventional batteries? —-
    To what extent can this electrical energy be amplified and/or modified?
    To what extent can this energy be stored?

    Very practical, and write great. Reading your article made me understand more.

    Thank you for sharing.

    I expect that the radiation produced would only be alpha or possibly beta particles. These are blocked by the skin, so couldn’t cause radioactive poisoning. Really neat idea!
