Lithium Power Doubles..... and gets cheaper too!
The boys (and girls) at Argonne National Laboratory have come up with a composite lithium battery. This will allow the batteries to made out of cheaper (and less energy intensive) materials. It also more than doubles the capacity of the battery which means your cellphones and laptops can run twice as long between recharges. This now means that the Tesla (shown below) can out accelerate (0-60mph in 4 seconds) and out last (>500 mile range) many sports cars and high end sedans.
Battery tech still has a long ways to go (especially price wise) but it's great to know that performance wise electric cars can compete with the best of the gas powered vehicles.
