Advanced technology for storing energy is a necessary foundation for a clean, sustainable energy system. Low-emissions transportation technologies such as plug-in hybrid electric vehicles require next-generation batteries with high energy, high storage capacity, and long life. Improved batteries are also essential for storing energy generated by intermittent renewable sources like solar and wind on the electricity grid.
The Environmental Energy Technologies Division's Electrochemistry Group conducts innovative research to understand the basic science of, as well as overcome technological barriers to next-generation batteries. Funded primarily by the U.S. Department of Energy, and based at the Lawrence Berkeley National Laboratory (Berkeley Lab), the Electrochemistry group is one of the world's leading centers for advanced battery research.
The Group devotes substantial effort to lithium-ion batteries, which are extremely promising for transportation applications, and it is developing a growing effort into batteries for electricity grid-scale applications. With input from the scientific community and the battery industry, the Electrochemistry Group is also expanding its research into newer promising battery chemistries.
