Scientists at the University of Cambridge (UK) successfully tested a model of lithium battery that brings that technology to a longer useful life and could enable electric cars have as much autonomy as fuel.
The experiment, whose findings were published in the journal Science, small-scale test the feasibility of battery on a combination of lithium-oxygen, which opens up the theoretical door to the production of lithium batteries to have limitations load.
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 receptor 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 electrodes graphene with larger pores that prevent barriers presented by current batteries.
The researchers hope that the findings of his study to accelerate mass production of lithium-oxygen more efficient with higher load both for 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.
Batteries Lithium-oxygen have a greater capacity on the space they occupy and could finally make an electric car 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 Clare Grey material, remember that the experiment is provisional and there are many obstacles to reach a phase of industrial production.
lithium-oxygen batteries developed so far are more unstable and inefficient in the long run, something that has prevented its expansion as an alternative.
