Lithium-ion batteries have become the quiet workhorses of the energy transition, but the way they are designed and tested has ...

China’s Dalian Institute of Chemical Physics, part of the Chinese Academy of Sciences, has reported research on a pre-lithiation battery design strategy that retained about 80% of capacity at −40°C ...

The lead-acid 12V auxiliary batteries are still a common thing in modern electric vehicles, despite the traction batteries are, in almost all cases, some kind of lithium-ion chemistry. That's probably ...

Recent incidents involving Tesla cars and Ford's F-150 Lightning electric pickup have led to production halts and investigations. U.S. researchers have developed a new lithium-air battery with a solid ...

Scientists work on new types of batteries that could be safer, more energy dense, or cheaper than existing Li-ion cells. Water-based batteries are promising, but they have a low energy density.

From the beginning of the electrification evolution, the U.S. has struggled to keep up with the Chinese battery giants, and has also fallen behind Europe in some battery production and adoption areas.

Sodium-ion batteries are an interesting alternative to lithium-ion, but they've been held back by complications due to their ...

Arguably the toughest hurdle facing EV designers is creating a battery pack that could power a vehicle for as much as 1,000 miles on a single charge. With that goal in mind, researchers at the ...

Batteries used in smartphones or in EVs normally charge for 10 hours on their first cycle, but turbo-charging them to 100% capacity in 20 minutes may lead to a 50% longer lifespan. When you purchase ...
