Lithium-ion batteries near theoretical limits as solid-state alternatives emerge

Recycled flavour. You've tasted this bagel before.
Summary
The lithium-ion battery, long dominant in smartphones, EVs, and drones, is approaching its theoretical performance limits. Scientists note that incremental improvements are no longer sufficient, as these batteries still suffer from cold-weather failure, capacity loss, and fire risks. Solid-state cells are presented as a promising alternative that would be faster and safer than current lithium-ion technology.

· 4 pulledLike any champion who spends too long at the top, the lithium-ion battery is stagnating.
Over decades as the battery of choice in everything from smartphones to electric cars and drones, its design has been tweaked countless times to improve its energy density and performance.
But, some scientists say, those improvements are approaching their theoretical limits.
Even the best models are prone to dying out in the cold, rapidly losing capacity or—as is the case for those in household devices—spontaneously catching fire.
