In five minutes .. a new technology to charge phones and laptops to save time

 Batteries taking too long to fully charge are an annoyance for many, but scientists at the University of Cambridge are now working to develop technology that will reduce charging times for laptops and phones to five minutes or less.

Scientists study the internal components of lithium-ion batteries to monitor the movement of ions in real time, and this low-cost technology will allow researchers to set "speed limits" for charging the battery - which can then be used to reduce charging times even more.

The research, published in Nature, could advance the development of next-generation batteries, which are necessary to wean humanity off its addiction to fossil fuels. Dr Ashkai Rao of the Cavendish Laboratory in Cambridge, who led the research, said: 'We found that there are different speed limits. for lithium-ion batteries, depending on whether they are being charged or discharged.

He added, “When charging, the speed depends on how quickly the lithium ions pass through the molecules of the active substance, and when discharging, the speed depends on how quickly the ions are introduced at the edges, and if we can control these two mechanisms, it will enable lithium-ion batteries to charge much faster.” .

Previous techniques for looking at batteries were time-consuming and expensive, such as electron microscopy and X-ray synchrotrons, but Cambridge's technology, using optical microscopy, offered better accuracy at a lower price - and used existing equipment.

Lithium-ion batteries are used in nearly every electrical device, from electric cars to smartphones - but high capacity and fast charging times are needed to be competitive with instantly available, energy-dense fossil fuels. Inside the batteries in real time.
