Russian laptop batteries last 10 hours
Russian scientists have developed a laptop battery that can work up to 10 hours without recharging, according to RIA Novosti news agency.

The new battery is based on fuel cells technology. That means it is fed with substance for electrochemical reaction - usually methanol or hydrogen - from outside.

Such power units can work as long as they are fed and do not need recharging.

“This is a sci-tech and market revolution based on Russian engineering designs,” said Prof. Lev Trusov, the project developer.

Trusov believes a modern laptop battery should weigh no more than 100-150 grams, and the Russian invention of a thin multi-layer nanostructure solves the problem of high energy density per volume unit.

The developers aim to make the new batteries to a high safety standard for users.

Trusov said a joint production agreement has been already signed.

Scientists Invent 30 Year Continuous Power Laptop Battery

Your next laptop could have a continuous power battery that lasts for 30 years without a single recharge thanks to work being funded by the U.S. Air Force Research Laboratory. The breakthrough betavoltaic power cells are constructed from semiconductors and use radioisotopes as the energy source. As the radioactive material decays it emits beta particles that transform into electric power capable of fueling an electrical device like a laptop for years.

Although betavoltaic batteries sound Nuclear they’re not, they neither use fission/fusion or chemical processes to produce energy and so (do not produce any radioactive or hazardous waste). Betavoltaics generate power when an electron strikes a particular interface between two layers of material. The Process uses beta electron emissions that occur when a neutron decays into a proton which causes a forward bias in the semiconductor. This makes the betavoltaic cell a forward bias diode of sorts, similar in some respects to a photovoltaic (solar) cell. Electrons scatter out of their normal orbits in the semiconductor and into the circuit creating a usable electric current.

The profile of the batteries can be quite small and thin, a porous silicon material is used to collect the hydrogen isotope tritium which is generated in the process. The reaction is non-thermal which means laptops and other small devices like mobile phones will run much cooler than with traditional lithium-ion power batteries. The reason the battery lasts so long is that neutron beta-decay into protons is the world's most concentrated source of electricity, truly demonstrating Einstein’s theory E=MC2.

The best part about these cells are when they eventually run out of power they are totally inert and non-toxic, so environmentalists need not fear these high tech scientific wonder batteries. If all goes well plans are for these cells to reach store shelves in about 2 to 3 years.

That said this could be a good thing the Russians have. I'm a bit dubious as it sounds like it requires a constant gas source to operate and recharge. We'll see if it shows up on the Market.

Lol - Russia's greatest cheer-leaders the @rse-licking Serbs celebrate an elleged russian 10yr battery. But the US have one that lasts x3 longer

Looooooooooooooooosers

Come and join the free World and everything is at least x3 better.

Did you know the average Russian male dies at the age of 59yrs old? So he lasts less time than 2 US laptop batteries.

Latest World news?

Nobody is licking arses. I am just posting the IT news. I see you are mad because of the fact the Russians have excellent scientists, and the big boss of yours whom you enjoy licking arse is a bit late and behind the Russians. Well, you should get over it. You will get a premature stroke like that if you don't

will this increase the life of a russian from 59 to 59 and 10 hours?!!!!

I heard of a new technique that going to have battery power last 10 times longer. So 40 hours > 10 hours :P

I don't know what the normal use time is for a laptop. Maybe 10 hours is amazing. But why use a constant gas supply for "continuous operation" when you can just plug it in to an outlet for that? Maybe I just don't understand.

Because then you wouldn't be stickin it to uncle sam.
