From the MIT, Institute technology of Massachusetts, just of announce that one of their teams of research has got design a new battery of litio-oxigeno that improves of way significant both in life useful as in efficiency energy to all the versions previous. As detail, facing batteries of lithium, models of lithium-ion – oxygen stand out by offering a very high density. In terms of data as such, note that one of these batteries can be 90% more effective, five times lighter and 10 times more powerful. One of its negative points, continuing with the comparison, is that only offered about 2,000 charge cycles.
Precisely because of its great qualities, have been many teams of researchers who have put hands to work to improve these negative points which, until now, made them impractical. Thanks to the results achieved by them researchers of the MIT is could be opening a new door, especially within a market as can be the of them cars electric and them devices electronic portable.
MIT litio-oxigeno battery exceeds many blackheads earlier presented updates.
As we said, this new type of batteries still have one disadvantages that make them little practice, among them add to the cycles of load that today they lose much of the energy in the form of heat, degrade relatively quickly and require fairly expensive additional components dedicated to pumping the oxygen inside and outside architecture that at the same time it is, contrary to the traditional, open-cell.
In terms of the work done by scientists at MIT in reference to litio-oxigeno batteries, note that they have managed to make a variation of the chemistry of the battery in such a way that now it would be presented completely sealed so it could be used as a conventional battery. This modification makes to reduce five times the tension that finally leads to a load much faster and improved efficiency while avoiding the gaseous state of oxygen makes that life can be extended.
During testing conducted using this system, the new prototype was exposed to 120 cycles of loading and unloading, showing a loss of less than 2% which means that this battery would have a longer shelf life. The team responsible for the development of this project hopes to be able to test a prototype optimised for 2017.
