Scientists at Berkeley Lab have designed an affordable ‘flow battery’ membrane that could accelerate renewable energy for the electrical grid.
Berkeley Lab scientists have uncovered an unexpected phenomenon in material interface chemistry that could help to control how metals corrode.
One issue plaguing today’s commercial battery materials is that they are only able to release about half of the lithium ions they contain. But for some reason, every new charge and discharge cycle slowly strips these lithium-rich cathodes of their voltage and capacity. A new study provides a comprehensive model of this process.
Researchers at the Berkeley Lab now have access to a unique new microscope that combines atomic-scale imaging capabilities with the ability to observe real-world sample properties and behavior in real time.

Several fields of research have sprung up around the chemical drivers, called catalysts, at work in many industrial processes – including those that boost the production of fuels, fertilizers, and foods – and there is a growing interest in coordinating these research activities to create new, hybrid catalysts with enhanced performance, say researchers at Berkeley Lab and UC Berkeley.
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 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.
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.
