Mapping Battery Materials With Atomic Precision

An international team led by researchers at Berkeley Lab used advanced techniques in electron microscopy to show how the ratio of materials that make up a lithium-ion battery electrode affects its structure at the atomic level, and how the surface is very different from the rest of the material.

Scientists Confirm Century-Old Speculation on the Chemistry of a High-Performance Battery

Scientists have discovered a novel chemical state, first proposed about 90 years ago, that enables a high-performance, low-cost sodium-ion battery. The battery could quickly and efficiently store and distribute energy produced by solar panels and wind turbines across the electrical grid.

Coupling Experiments to Theory to Build a Better Battery

A Berkeley Lab-led team of researchers has reported that a new lithium-sulfur battery component allows a doubling in capacity compared to a conventional lithium-sulfur battery, even after more than 100 charge cycles.
