Simplifying Gadgets and Technology, is my passion!
Donut Lab introduced what it claims is the world’s first commercially available all-solid-state battery at CES 2026 in Las Vegas, marking a pivotal moment in the decade-long race to bring the promising technology from laboratory […]
It will be a lot clearer if you watch the video in the linked article, as the article text does not really clearly summarise all the conclusions. See https://hackaday.com/2025/11/10/testing-whether-fast-charging-kills-smartphone-batteries-and-other-myths
“By the time the car had covered over 300,000km, the pack still had well over 80% of its original capacity available.” Well, there goes that theory that batteries won’t last very long. Ironically enough, it […]

The biggest change lies in the anode—the part of the battery that stores and releases electrons during charging. Traditional lithium-ion batteries use graphite here, but silicon-carbon batteries replace it with a silicon-infused anode. Why? Because […]
Bottom line is, you really cannot trust ad hoc online or flea market sellers (and neither Facebook Marketplace sellers). As shown in this video, even 500+ “positive” reviews really mean nothing at all. That online […]
More and more devices now come kitted out with rechargeable lithium-ion batteries — you know, the ones that look like the old-style AA or C cell batteries, but are a slightly different size. The most […]
