The new batteries of lithium-oxygen will revolutionize electric vehicles
Scientists of Cambridge, Uk, are developing a new batteries of lithium-oxygen that promises to overcome all the barriers to the current lithium-ion battery. Still in prototype phase, these super-batteries to make as many miles as a vehicle of conventional combustion.
These batteries cost a fifth part, and have a density theoretical ten times higher
the future is electric, we have no doubts. However, the increased ballast of the electrical is still their battery pack, an item expensive and heavy. We must not forget the so-called “anxiety of autonomy” of electric vehicles, although this problem is gradually fading away especially in models of higher category as the Tesla Model S.
The above-mentioned batteries, lithium-oxygen would not have these drawbacks since can cost a fifth of the price of the current and its time to own the fifth part of its weight. This is because the density to theoretical of these batteries are up to ten times higher the lithium-ion battery.
Without the problems of weight, cost, and autonomy an electric can be as practical as a combustion vehicle, however it is still yet to overcome the obstacle that represents the charging time. Vehicles like the Nissan Leaf require at least 30 minutes for a quick charge of up to 80% of its capacity.
More than 2,000 recharges
These new batteries can still be object of research during the next ten years due to the ability of loading and unloading of these is very low. However, researchers are ahead of that have a efficiency rate of 93% and can be recharged more than 2,000 times.
The race for the batteries perfect not just begun. In addition to these lithium-oxygen, there are already in the process of research other batteries based on sulfur as well as the polymer batteries of graphene whose main component is manufactured by a Spanish company to an industrial level.
