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

Tiny lithium-ion battery packs power in small size

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.

Amazon quietly upgrades its Fire HD 10 tablet with a whopping 1GB of RAM
Amazon really said, "Here's 1GB. You're welcome."
Amazon Fire HD 10 tablet

Amazon has quietly refreshed one of its most popular tablets, but not in the way many expected. Instead of launching a brand-new Fire tablet after its longest product drought in years, the company has introduced a slightly upgraded version of the existing Fire HD 10 with an extra gigabyte of RAM.

The update is modest on paper, yet it arrives at an interesting time. Amazon hasn't introduced a new Fire tablet since the Fire HD 8 refresh in 2024, while products like the Fire 7 and Fire Max 11 have yet to receive successors. Rather than expanding its lineup, Amazon appears to be extending the life of an aging device with a minor hardware tweak.
