A team of scientists from the University of Cambridge (UK) has successfully tested a model of battery Lithium longer than at present, and could enable electric cars have the same autonomy than gasoline, according to the magazine “Science”.
The small-scale experiment to test the feasibility of a battery containing lithium and oxygen, which opens the door theoretical production of lithium batteries so far are limited in their capacity.
At present, the ability of battery lithium is limited by the formation of lithium peroxide during discharge, which decreases the efficiency of the battery irreparably by blocking the micropores of the anode receiver, usually carbon.
The design of this new battery includes an electrode negative metal lithium, a nonaqueous electrolyte and positive electrode current, by adding lithium hydroxide and peroxide instead graphene electrodes with larger pores, prevent the barrier having the battery .
The researchers hope that this advance could accelerate mass production of battery lithium-oxygen load and more efficient for both electric cars to electronics.
The ability of the battery of conventional lithium ion around 80% of rated capacity, as proven by scientists at the University of Cambridge can exceed 93%.
In addition, this new device can be recharged more than 2,000 times and is highly resistant to water, one of the problems of the battery Current.
device has a higher load capacity on the space occupied and could finally make an electric car you have the autonomy to gasoline.
However, these battery of lithium oxygen are more unstable and inefficient in the long term, which has avoided that arise as an alternative
