Gallery: New Lithium-Ion Batteries Could Significantly Extend the Range...


Range anxiety is one of the biggest hurdles facing electric cars today. For electric vehicles to truly become mainstream, batteries will have to provide a longer range and become much cheaper. Now, researchers from South Korea have developed an advanced lithium-ion battery that has a high energy content and rate capacity — making electric cars even more competitive than their gas-powered counterparts.

Using an electrode combination of a tin-carbon anode and a lithium-ion cathode, researchers have created a battery that can store more energy and is smaller than electric batteries currently available. The high rate capacity also allows the battery to be used in really low temperatures, which was another issue holding electric vehicles back.

“These unique features make the battery a very promising energy storage for powering low or zero emission HEV or EV vehicles,” they say. “This battery is a top candidate for powering sustainable vehicles.”

While conventional lithium-ion batteries typically have an energy density of about 120-150 Wh/kg, the advanced lithium-ion battery offers about 100 high rate cycles of rate capability and energy density of the order of 170 Wh/kg, reported IB Times.

The battery is not likely to be out on the market for a few years, but this development is likely to go far in making electric cars mainstream.

    Personlly I think they should use small 50CC motors connected to an alternator or generator to generate electricity and use that energy to drive an auto. Coupled with breaking generators for added power. Far more efficient than todays standard v6 engines I think. Guessing 65 miles to the gallon.

    Until they get 300 miles on a single charge and a recharge rate of 10 minutes or less electric cars won\\\’t be main stream. Mainly because fewer than 40% of the population have a means to charge at home. So gas/electric stations need to fill up in nearly the same time as it now take to fill a 30 gallon gas tank.

    Where’s my Electric / Diesel plug-in hybrid VW Golf option?

    I want that one. 50km on battery, and a Golf TDi as well?

    Yes please. Until then, go away with the electric Noddy cars.

    Range anxiety (Erangetile Dysfunction?) is not what worries electric car makers these days. What worries them is that the fact that NOBODY is buying their cars, and that despite massive gov’t intervention and interference, they can’t get out of second gear in selling these things.

    Great news. What about the security of this system? Li-iron phosphat are used for EV despite their slightly lower energy density, however they are much more userfreindly and save.
