Scientists successfully prove more durable lithium battery – ABC Color

WASHINGTON. Scientists at Cambridge University have successfully tested a model of lithium battery that brings that technology to a longer useful life and could facilitate the electric car has as much autonomy as gasoline.

The experiment, whose findings published in the journal Science today, small-scale test the feasibility of a combination battery of lithium-oxygen, which opens the door to theoretical production of lithium batteries have limited capacity to load.

At present, the capacity of lithium batteries is limited by the formation of lithium peroxide during discharge efficiency blocking irremediably battery by blocking the micropores of the anode receiver, typically carbon.

The design of this battery includes a lithium metal negative electrode, a nonaqueous electrolyte and a positive electrode, that by adding lithium hydroxide instead of peroxide and graphene electrodes with larger pores that prevent the barrier presents current batteries.

The researchers hope that the findings of his study to accelerate mass production of batteries Lithium-oxygen more efficient, more burden on both electric cars to electronics.

The battery capacity of conventional lithium ion around 80% of rated capacity, while proved by researchers at the University of Cambridge can exceed 93%. In addition, new experimental batteries can be recharged more than 2,000 times and are more resistant to water, one of the problems of current batteries.

The lithium-oxygen batteries have a higher capacity relative the space occupied and could finally make electric cars have the autonomy of a gas tank, something that would revolutionize a clean technology that gradually becomes more popular,

However, the scientists, led by professor of chemistry at Cambridge material Clare Grey , remember that the experiment is provisional and there are many obstacles to reach a phase of industrial production.

The lithium batteries Oxygen developed so far are more unstable and inefficient in the long run, something that has prevented its expansion as an alternative.
