Are you tired of your short laptop battery life with only a few hours?

Are you tired of your short laptop battery life with just a few hours? Want to charge your mobile phone to last a couple of months? Well, the answer to their "sentences" could be that nuclear batteries have been developed at the University of Missouri.

They are specially designed to provide a lasting source of energy. And some people think that these batteries could replace the current ones, including those used by electric cars. According to the creators, a battery has a capacity to generate nuclear electricity very large compared to a normal.


Batteries have always been the Achilles heel of mobile devices. In general, designers of consumer electronic devices (like laptop computers or media players) use small screen or screens laptop batteries dell notebook battery are not very bright to save scarce energy resources that are provided to regular batteries. But new nuclear battery would create a solution based on a semiconductor liquid (instead of a solid semiconductor) to produce a much longer life battery.

The reason is that solids semiconductors are constantly attacked by some radioactive elements used by other types of batteries, while the liquid semiconductor is quite resistant to these attacks.


Although the term "nuclear" may be a bit disturbing, the fact is that these batteries are not very different from those used batteries, for example, medical pacemakers.

The new radioisotope battery is the size of a coin and provides much more power than traditional ones because, according to research, its capacity is much higher. Jae Kwon, assistant professor of electrical and computer engineering at the University of Missouri, said radioisotope battery "may provide a power density that is six orders of magnitude greater than chemical batteries." In other words, offers no less than a million times more cargo than any other "normal" battery.


Kwon and his research team have spent enough time working to solve many problems encountered in the development of this type of battery. One important thing is that the batteries need to be small and thin to be practical and useful, therefore, could be used to power watches and small electronic devices.


As mentioned before, the prototype (which you can see in the picture below) has the size and thickness of a dime, but researchers believe they can get a thinner battery. To do this, Kwon has required the help of another teacher: J. David Robertson (professor of chemistry and associate director of the MU Research Reactor). In general, the laptop power cord hope of maximizing the nuclear battery power and reduce the size and evidence of other materials to make improvements.

Kwon believes that the end of the battery, to be used in commercial equipment may be thinner than a human hair. For now, the research team have required a provisional patent to protect the exclusive right to use this invention.
