Scientists at the University of Cambridge (UK) have successfully tested a model of lithium battery about this technology to a longer life and could facilitate the electric car has as much autonomy as fuel.
The experiment, whose findings published Thursday magazine Science , small-scale test the feasibility of a combination battery of lithium-oxygen, which opens the theoretical production of lithium batteries that have limited capacity to cargo door.
At present, the capacity of lithium batteries is limited by the formation of lithium peroxide during discharge blocking battery efficiency inevitably to block the micropores of the anode receiver, usually carbon.
The design of this battery includes a lithium metal negative electrode, a nonaqueous electrolyte and a positive electrode, that by adding lithium hydroxide and peroxide instead graphene electrodes with larger pores avoiding the barrier presents current batteries.
The battery capacity of conventional lithium ion around 80% of rated capacity, while proved by researchers Cambridge University can exceed the 93% .
Lithium batteries have a higher oxygen-carrying capacity relative to space deal 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, scientists , led by professor of chemistry material Cambridge 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.
