Energy Storage

Clean, efficient technologies capable of storing and delivering energy on timescales from seconds to hours are critical for enabling a carbon-free, sustainable energy system.  Low-emissions transportation technologies such as plug-in hybrid electric vehicles and battery all-electric vehicles require next-generation batteries featuring good safety, high energy density, long life and low cost. Large-scale batteries of similar characteristics (excluding perhaps the requirement of high energy density) are also essential for storing energy generated by variable renewable sources like solar and wind for the electricity grid.

The Energy Technologies Area’s Energy Storage Group conducts innovative research to understand the basic science of energy storage, as well as to overcome technological barriers to next-generation batteries. Funded primarily by the U.S. Department of Energy, and based at Berkeley Lab, the 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 growing its research on batteries for electricity grid-scale applications, such as flow batteries. With input from the scientific community and the battery industry, the group is also expanding its research into newer, promising battery chemistries like sodium and zinc.

Key Topics:

  • Li-ion and Li/Sulfur
  • Surface and bulk materials analysis
  • Transport and systems modeling
  • Cell fabrication and failure analysis
