What if charging your phone took less time than brushing your teeth? A new study published in Proceedings of the National Academy of Sciences could very well hold the key to a next-gen charger capable of recharging your phone in just 60 seconds.

Researchers from the University of Colorado Boulder have discovered a new cutting-edge technique that could make it possible to charge devices almost instantaneously. This would make charging phones, laptops, and even electric cars much more efficient and convenient. The foundation of the new technique is based on new insights into how ions move through supercapacitors.

The key, one of the researchers explains in a press release, is to make the movement of the ions more efficient. By doing this we can make the charging and release of energy much faster, allowing for that next-gen charger that is capable of boosting your phone’s charge from 0 to 100 in just a minute, or maybe even less.

To make this discovery, the researchers looked at the movement of ions through a complex network of interconnected pores running through the supercapacitor. Their findings have helped modify a scientific law that researchers have used to govern electrical currents for more than 175 years. This law, called the Kirchhoff circuit law, describes the flow of electrons in a simple loop of wiring in most classes.

However, when inspecting the ions and their movement, the researchers found that the ions move fundamentally differently at the intersections of tiny nanoscale pores when compared to how electrons move near the same locations. Further observations helped them determine that these movements are different from what Kirchhoff’s law describes. This doesn’t completely throw out the old laws, though, as they still provide valid explanations for how electronics flow within conventional electronic circuits.

However, to create a next-gen charger capable of taking full advantage of the movements of the ions, we have to look at things different. This, the researchers say, is “the missing link” that they have been looking for. Creating more efficient energy storage has been a long-term goal for many engineers.

We’ve seen water-based batteries capable of storing more than traditional lithium-ion batteries. Still, a method that lets us charge our batteries almost instantly would remove a lot of the hindrances surrounding the wider adoption of things like electric cars. Not to mention how much more convenient a next-gen character would make charging laptops, phones, and other electronic devices.

      Consider that the energy output of a 12-gauge shotgun is approximately 4500 Newton-meters and, from personal experience, can rotate a first-gen iPad at an extrapolated 240 rpm (extrapolated as this proved difficult to sustain). That gives us an equivalent of 113 kW! A modern ipad would only need about 13 kW to charge in one second.

      So, one shotgun shell could easily charge yours and 7 of your friends ipads instantaneously, although the results are difficult to appreciate.

        probably because they currently don’t get stuffed a bucketload of crackly juice* in 60 seconds

        *I don’t, in fact, know how electricity really works

        Been charging my phone overnight for years. Battery health is 100% and I never have to worry about charging.

          Impossible for battery health to be at 100% after years. May still be working great, but not 100%.

            Battery degradation is ridiculously unpredictable. I’ve seen 100 cycle batteries at 75% and 2500 cycle batteries over 90%. I only dealt with like 5 MacBook models

              Agreed, but not a “charge overnight for years” but no degradation at all.

                Depending on what battery protection modes are in play, many have smart charging or other features designed to prolong life. Also a fair few batteries come out with greater than design capacity from the factory. It’s called a design capacity and not an absolute capacity for a reason. A phone battery that left the factory at 110% could conceivably still be at or above 100%.

                Fyi it’s not overnight charging that’s the issue either, it’s charging to 100%. What one device consider 100% varies and devices will essentially lie to you about it. 4.2V is normally considered 100% full for Lithium Cobalt Oxide batteries yet some devices push higher than this while others skirt under to pad capacity and cycle life respectively. It’s about tradeoffs.
