I made this amazing battery pack using 18650 cells, performing about 3X better than a LiPo battery of roughly the same weight ...

[Alex Hao] and [Andreas Bastian] of Lumafield recently visited with [Adam Savage] to document their findings after performing X-ray computed tomography scans on over 1,000 18650 lithium-ion batteries.

Chicago-headquartered NanoGraf Technologies, which claims it has enabled the highest energy-density cylindrical 18650 Lithium-ion cell in the world, today announced that its battery has achieved a new ...

The vast majority of our portable electronic gadgets, and the new wave of electric transportation, are powered by lithium batteries. Texas-based startup Group1 has developed a more sustainable ...

Group1 has made significant strides in battery technology with the introduction of the world’s first 18650 cylindrical potassium-ion battery. This innovative development could offer a viable ...

Recently I bought a few portable power supply devices to run my little microcontroller projects. There are countless variants of portable power supply devices that can be used to power up most ...

This summer, we saw the WHY (What Hackers Yearn) event happen in Netherlands, of course, with a badge to match. Many badges these days embrace the QWERTY computer aesthetic, which I’m personally ...

A team of researchers in France has taken a major step towards powering our devices with rechargeable batteries based on an element that is far more abundant and cheaper than lithium. For the first ...

Since the late 1990s, the 18650 lithium-ion rechargeable cell has been a common standard cell used in many devices and a host of applications. Like the ubiquitous AA, AAA, C, and D alkaline primary ...

I find myself in need of welding 40 18650 cells into a pack to rebuild a dead pack. It seems the normal method of doing this is spot welding the batteries together with thin nickel sheet. Does anyone ...
