Lithium-ion batteries generally degrade fastest when held at a high state of charge, which means keeping your iPhone or your Mac's battery at 100 percent accelerates the chemical wear that permanently reduces its actual capacity over time.

Ascend Elements has started Chapter 11 bankruptcy proceedings in the U.S., a heavy blow to investors who had sunk nearly $900 million into the company.

Nio's stock rose 6% in Friday's session, climbing from a prior close of $6.07 to $6.45, as investors cheered a pair of milestones that bulls have been waiting years to see.

The Zepath 3600mWh is the only rechargeable lithium-ion AA I'd buy for myself - even though USB-C is in the charger, rather than each individual cell.

Together, we developed a high-voltage battery system that unlocks the full potential of the new cylindrical cells in record time, delivering significant improvements in energy, range, and charging performance.

The group points out, correctly, that the grid is designed for brief bursts of high demand; most of the time there's lots of capacity that goes unused. Utilize thinks that should change. The group argues that smarter ways to use that capacity already exist. Utilize name checks a number of those solutions, including battery storage, demand response, and virtual power plants, all of which have emerged en masse over the last decade, but remain under utilized.

While the abrupt end to your home chef experience is inconvenient, the bigger issue is that your gas furnace still needs electricity to run, and it's supposed to drop into the 20s overnight. Now imagine that while everyone else is rifling through their junk drawer for flashlights and batteries,

CATL says its new 5C batteries will retain 80% of their capacity after 1,400 charge-discharge cycles at 140F (60C). With a theoretical range of 372 miles (600 km) per cycle, that works out to a total of 522,000 miles (840,000 km) in what CATL describes as Dubai summer heat. At a milder ambient temperature of 68F (20C), which is closer to the ideal operating temperature for lithium-ion batteries,

Battery degradation on high-mileage EVs is not as big a deal as some might make you believe. Real-world data shows that EVs with over 150,000 miles are still going strong, with minimal degradation. Older EVs are more affected by high mileage, but technology has made newer models more resilient. Battery degradation is inevitable, but new research shows that EV owners should just keep driving their cars without worrying about what happens with the thousands of cells that live in their cars' floors.

The first sites are expected to open later this Summer, and will be built at select locations along I-5 and I-10, major routes for commercial vehicles and significant logistics companies. The chargers will be available in California, Georgia, Nevada, New Mexico, and Texas. Each station will have between four and eight chargers, delivering up to 1.2 megawatts of power at each stall.
