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.

The iPad is finally getting the Affinity app creatives have been asking for
Affinity brings photo editing, vector design, page layout, and sketching together in one free iPad app.
Affinity UI on iPad

Affinity’s new all-in-one creative app is finally coming to the iPad, nearly a year after Canva launched the redesigned desktop version for Mac and Windows. Creatives have been asking for the iPad release ever since, especially because files created in the new Affinity app cannot be opened in the older V2 iPad apps.

Affinity already has Photo, Designer, and Publisher apps on iPad, but the new release combines those tools into the same unified app that Canva launched on desktop last year.

Apple’s “Pro and Tell” October 28 event: Everything we expect from touchscreen MacBooks to a new iMac
Prepare for a touchscreen MacBook that costs around $3,000.
Computer, Electronics, Laptop

Touchscreen laptops have been around for years. You can get them in all sizes and shapes. Just not from Apple. For years, the Cupertino giant has treated the idea of a touchscreen MacBook the way I treat a meeting that could have been an email: with open contempt. However, Wednesday looks like the day the company could finally change its mind. 

The latest Apple invite puts the “Pro and Tell” showcase in Los Angeles at 10 a.m. PT (1 p.m. ET) on October 28, 2026. Instead of a regular live-streamed keynote, it is an invitation-only, hands-on event for a handful of press and creators (similar to what the company did for the MacBook Neo earlier this year).

Apple will only give you the fastest iPad mini chip if you pay $999, or more
The full A20 Pro experience on Apple’s new iPad mini is reserved for buyers spending at least $999.
Apple iPad mini with 6-core CPU

Apple has just launched its latest iPad mini with a notable set of upgrades, including an OLED screen, improved speakers, and a more resilient build. It also gets a new chip, and the whole package costs $200 more than its predecessor. But if you look closely at Apple’s online store, you’ll realize that $699 isn’t enough to get you the most powerful version of the A20 Pro chip inside this tablet. In fact, even if you pay $800 for the 256GB model, you still won’t get the beefiest variant. Only when you jump to the 512GB trim, which costs an absurd $999, do you get the most powerful flavor of the A20 Pro.

The $999 model gets more than extra storage
