New Batteries for Electric Cars Could Last Ten Times Longer

By John Farrier in Science & Tech on Aug 17, 2009 at 12:23 pm

Researchers at Toyota and Tohuku University in northern Japan have announced progress in their efforts to extend the charge in the batteries of electric vehicles:

Existing lithium-ion batteries have a cathode that contains graphite and polycrystal lithium cobalt oxide with the graphite improving the performance of the cathode but also requiring space that could be theoretically used to store more lithium ions.

The researchers say it will take up to ten years to develop a cathode with no graphite and single crystals of lithium cobalt oxide but that the end result is a powerful battery for electric cars, which can store 10 times more electrical charge. As a result, electric cars could travel ten times farther than they can today.

    Bet the designers will get pushed by the marketing department to make them go faster instead of further.

    There is a lot of interest in the lithium iron phosphate batteries produced by Chinese automaker BYD. They are cheaper and last longer than lithium-ion, and they’re safer (don’t explode, even under crash conditions). They are, however, heavier.

    How is it you can say you know how to do something, but can’t do it for another ten years?

    I would never buy a electric car or even a hybrid electric car. They are not worth the money and especially not worth the cost of repair.

    Hydrogen vehicles are safer and can get better mileage plus they produce 0 emissions. They just need to stop with the hydrogen fuel cell thing. That is just pointless and make the cost go even higher. Just strap a few tanks on the car an go. They are not going to explode unless you have some extreme heat.

    On a plus side is current vehicles can be converted to run hydrogen. There is no need to go out and buy a whole new car. Just get a conversion kit and run hydrogen instead. Oil companies plus the government are really the only people stopping it because of what it will do to the economy. It will destroy an industry and take away a huge amount of money from the government. People would not be able to take a +$1 tax on a fuel source that can be made at home.

    The university, by the way, is Tohoku University (not Tohuku, as incorrectly posted in the original). It’s one of the oldest and most prestigious universities in Japan.

    Television existed before WW2, but it took quite a long time to develop it to general consumption. I think we are at the end of the gasoline era, I think the exponential growth in technology will bring it about sooner than ten years. Hydrogen or Electric, we will be seeing bluer skies.

    And where does all that environmentally friendly hydrogen come from? Like bioethanol, it currently takes more energy to produce hydrogen then hydrogen provides as a fuel.

    Hi,

    Thanks for writing such an interesting article. Its really good to know about the batteries in detail. Seriously do we realize how many things in your house that need batteries? Let’s count it, from the flashlight, cell phone, iPod, cameras, and many more. Knowing it should make us realize on how essential the presence of the batteries in our daily life. However, with that so many kinds of battery, which is generally different between one to another, sometimes we have some difficulties in finding the desired type.

    Find the right batteries supplier is not hard if you check out batterystation.co.uk because this website provides the widest selection of batteries and you can choose the right battery based on the categories. You can get the procell batteries which available in several sizes and voltage. You also can find Duracell batteries that divided into duracell plus batteries and duracell ultra batteries. All of the batteries come with cheaper price because this website provides the discount batteries in bulk, wholesale, and retail quantities.

    Thanks,
    Mike
