We’re all used to it by now, but I’d just like to reflect on how insanely power-packed lithium ion batteries are, and everything that’s afforded us. I’m trying to think …read more Continue reading The Unreasonable Power Density of Lithium-Ion
Lithium-ion cells deliver very high energy densities compared to many other battery technologies, but they bring with them a danger of fire or explosion if they are misused. We’re mostly …read more Continue reading Lumafield Shows Why Your Cheap 18650 Cells Are Terrible
Often times, e-bikes seek to build the biggest battery with the most range. But what if you want to take a couple lunch loops on your bike and only need …read more Continue reading Making the World’s Smallest E-Bike Battery
A hefty portable power bank is a handy thing to DIY, but one needs to get their hands on a number of matching lithium-ion cells to make it happen. [Chris …read more Continue reading Save Cells from the Landfill, Get a Power Bank For Your Troubles
If you’ve ever worked with adding lithium-ion batteries to one of your projects, you’ve likely spent some quality time with a TP4056. Whether you implemented the circuit yourself, or took …read more Continue reading Playing Around with the MH-CD42 Charger Board
Researchers have been testing a new type of lithium ion battery that uses single-crystal electrodes. Over several years, they’ve found that the technology could keep 80% of its capacity after …read more Continue reading Single Crystal Electrode Lithium Ion Batteries Last a Long Time
China leads the world in terms of renewable energy resources like solar power. And not just by a small margin either, making over twice as much solar power as the next highest country, the USA. Where do you store any excess solar energy for use when th… Continue reading New grid battery packs record energy density into a shipping container
Battery management is a tedious but necessary problem that becomes more of a hassle with lithium-ion technology. As we’re all very aware, such batteries need a bit of care to …read more Continue reading Hardware Reuse: The PMG001 Integrated Power Management Module
“Please say it wasn’t a regex, please say it wasn’t a regex; aww, crap, it was a regex!” That seems to be the conclusion now that Crowdstrike has released a …read more Continue reading Hackaday Links: August 11, 2024
Lithium is a finite resource, and the more we lock inside rechargeable batteries, the less we have to use. A new speedy method to free the element from such sources could be a game changer in terms of the material’s availability.Continue ReadingCategor… Continue reading Microwave technique recovers 87% of batteries’ lithium in 15 minutes
