Unraveling lithium ions or how the University of Cambridge works so that we can charge our smartphones in record time.
With the Lithium-ion technology Almost exhausted of improvements, the industry is actually no longer striving for more density or greater capacities, but rather high charge rates A smartphone can be fully charged in just 5 or 10 minutes.
The first company that tried was Xiaomi, no less that he presented his 200W HyperCharge to us with a great roar and shortly after he realized that these forces are actually draining the batteries faster than they would like, problems that also the Chinese government in terms of ultra-fast wireless charging and the related interference doubted could cause.
In any case, the industry is not stopping and the next move is being made by the University of Cambridge which has published an article on their studies inexpensive techniques to examine the inside of lithium-ion batteries and improve their efficiency and performance, including load capacities, which the researchers say would be “breakthrough”.
A research group from the University of Cambridge is working on the lithium-ion technology of our batteries to uncover the speed limits and thus achieve unprecedented charging efficiency with which even smartphones could be charged in less than 5 minutes.
As it is obvious, for now we don’t know the details of a study that for the time being there has only been progress in an article published in the last few days that reports on an inexpensive technique with which one can observe and discover the inside of lithium-ion batteries in a previously impossible way There are different speed limits for downloading and charging this type of energy storage.
So they could Study cycles to maximize potential Depending on whether a battery is being charged or discharged, Dr. Ashkay Rao of the Cavendish Laboratory in Cambridge, who led the research team.
When charging, the speed depends on how fast the lithium ions can pass through the active material particles. When discharging, the speed depends on how quickly the ions are inserted at the edges. If we can control these mechanisms, we will be able to charge lithium-ion batteries much faster.
As the researchers add, it is no longer necessary to observe the inner workings of lithium batteries with expensive techniques such as electron microscopy or synchrotron X-rays this novel technique called interferometric dispersion enables phase transitions in charge / discharge cycles to be observed faster and more cost-effectively, to better study the behavior of lithium ions to understand how quickly the cycles can be completed.
Is about a very important investigation, not only for smartphones, but for all kinds of devices, devices and even vehicles that use lithium-ion as energy storage, because this technology was practically exhausted in terms of improvements and slow loading times make the necessary transition to models that are less dependent on fossil fuels difficult.
The high forces Used by Xiaomi also do not seem to be the solution to the problem, since can increase the temperature of the battery and even cause it to explodewhich is why research from such authoritative voices gives us an outlook for a more promising future.
This lab technique we developed offers a big change in the speed at which the technology can evolve so that we can keep up with the fast paced insides of a battery. The fact that we can see these phase limitations in real time while charging is truly amazing, and this technique could be an important part of the development of next generation batteries. Dr. Christoph Schnedermann from the Cavendish Laboratory.
Undoubtedly interesting news that Independent sent us from the UK, for the time being without too many details beyond that Sufficient speeds could be achieved to charge a portable battery in less than 5 minuteswithout also causing the deterioration suffered by high load forces … Let’s see when the future comes!
