New, tiny lithium-ion battery can recharge in less than a second

The old, bulky lithuim-ion battery has finally been innovated with enough power to boost a car battery and still recharge in seconds.

It may not be essential to running the newest version of Android, but a tiny, microbattery with that level of power and recharge rate spells success for more power-hungry equipment like electric cars, radio broadcasts, etc. But it certainly doesn’t hurt that the microbattery, developed by researchers at the University of Illinois at Urbana-Champaign, is only a few millimeters in size, which means new mobile devices with slimmer profiles, longer battery life, and less time spent tethered to an outlet.

the microbatteries will recharge 1000 times faster than current technologies

William P. King, who led the research, wanted to make the battery smaller, so size was definitely a factor, but the research went beyond that. A drawback of current power sources is the required choice between power and energy: a cell either releases energy very quickly, stores a small amount, and recharges quickly or releases energy more slowly and takes longer to charge. The latter is what powers your smartphone.

The new microbatteries change that dichotomy by offering both high performance and quick-charging capabilities in one package. The new design uses a fast-charging cathode (the positive side of a battery) designed Paul Brian, another professor at the University. King and his team then developed a matching anode (the negative side) and found a way to put the two together.

So how does this kind of power translate to real-world situations? The batteries could, in theory, broadcast radio signals 30 times farther than normal and enable devices to be about 30 times smaller. More impressive, the microbatteries will recharge 1000 times faster than current technologies. King uses medical devices and implants as an example, “where the battery is an enormous brick, and it’s connected to itty-bitty electronics and tiny wires. Now the battery is also tiny.”

That translates to impossibly-thin devices that won’t have to be plugged in for more than a second. At present, technology is fairly limited by our battery technology, especially when it comes to medicine. However, a tiny battery will also allow us to create tablets that can easily be held in one hand for any amount of time and laptops that won’t weigh you down. Assuming they can get the producton costs down, tiny batteries could usher in a new era of mobile tech.

AT&T just made it a lot easier to upgrade your phone

Do you want to upgrade your phone more than once a year? What about three times a year? Are you on AT&T? If you answered yes to those questions, then AT&T’s new “Next Up Anytime” early upgrade program is made for you. With this add-on, you’ll be able to upgrade your phone three times a year for just $10 extra every month. It will be available starting July 16.

Currently, AT&T has its “Next Up” add-on, which has been available for the past several years. This program costs $6 extra per month and lets you upgrade by trading in your existing phone after at least half of it is paid off. But the new Next Up Anytime option gives you some more flexibility.

The Nokia 3210 is the worst phone I’ve used in 2024

Where do I even start with the Nokia 3210? Not the original, which was one of the coolest phones to own back in a time when Star Wars: Episode 1 -- The Phantom Menace wasn’t even a thing, but the latest 2024 reissue that has come along to save us all from digital overload, the horror of social media, and the endless distraction that is the modern smartphone.

Except behind this facade of marketing-friendly do-goodery hides a weapon of torture, a device so foul that I’d rather sit through multiple showings of Jar Jar Binks and the gang hopelessly trying to bring back the magic of A New Hope than use it.
The Nokia 3210 really is that bad
