Lithium-ion batteries can become unstable under certain conditions, leading to fires. Now, researchers have used new materials that they say can make batteries safer.

Lithium-ion batteries, or "Li-ion" for short, are one of the most ubiquitous forms of portable power in the world today. Most handheld devices like smartphones use Li-ion batteries, though scaled-up ...

Wesley Chang is an assistant professor of mechanical engineering and mechanics at Drexel University. Rechargeable batteries are great for storing energy and powering electronics from smartphones to ...

It is often said that LFP batteries are safer than NMC storage systems, but recent research suggests that this is an overly simplified view. In the rare event of catastrophic failure, the off-gas from ...

Lithium-ion batteries have taken up permanent residence in our homes for years now. They're hidden in your phone and laptop, but they might also lurk in your electric toothbrush or your bike. Even ...

Sodium-ion batteries for electric vehicles and energy storage are moving toward the mainstream. Wider use of these batteries could lead to lower costs, less fire risk, and less need for lithium, ...

Sodium-ion batteries are popping up in electric scooters and grid storage installations. Lithium-ion batteries have some emerging competition: Sodium-based alternatives are starting to make inroads.
