Batteries for Advanced Transportation Technologies

The Batteries for Advanced Transportation Technologies (BATT) Program is the premier fundamental research program in the U.S. for developing  high-performance, rechargeable batteries for electric vehicles (EVs) and hybrid-electric vehicles (HEVs). While this program includes researchers from all over the US, a large portion of the work is carried out at LBNL in the BESTAR Groups.
BATT is supported by the U.S. Department of Energy Office of Vehicle Technologies (OVT) and is managed by the Lawrence Berkeley National Laboratory (LBNL) as part of its Carbon Cycle 2.0initiative. More information on this program can be found at the BATT Website.

Theory and Modeling

Untitled-5Untitled-4
First-principle calculations are used to predict and provide a detailed understanding of the interactions between bulk composition, surface structure, and fundamental material properties such as ionic and electronic transport phenomena.  Further, sophisticated mathematical modeling is applied to support physical understanding to the very complex interactions of cell components.

New Electrode Materials

XBD200906-00201-01.

The Group is working to identify new electrode materials for higher-energy and higher-
power batteries of the future. Materials under consideration for anodes (the negative electrode) include non-carbonaceous materials such as silicon-based compounds. For cathodes, the current focus is on high-voltage spinels and layered materials

Advanced Diagnostics Techniques

The Advanced Diagnostic Group uses state-of-the art tools to investigate the natural processes that limit the lifetime and performance of batteries.

Electrode Architecture

XBD200906-00201-01
The Group studies the electrochemistry of the architecture of the battery cell as well as its individual constituents. The goal is to develop optimal cell and component design to maximize power, energy, capacity, and lifetime.
