High Energy-Density Electrodes via Modifications to the Inactive Components and Processing Conditions: My AMR Oral Presentation
Abstract
Our group investigates the challenges of making dense, high loading electrodes for EV applications. Last year, through a combination of primary and secondary particles of LFP, we developed a process for producing LFP electrodes of 5 mAh/cm2 that can be calendared to 40% porosity that do not delaminate during calendaring or the electrode cutting process. This year we took on the challenge of preparing thick electrodes via an aqueous process of primary particles of LMFP synthesized via the solid-state process that results in material of a wide particle size distribution that spans from 10’s of nanometers to microns. We are using a Gaussian Process (gpCAM) computing package developed in CAMERA to accelerate our search for the thickest electrodes with no-cracks and low resistivity.

Vincent BattagliaVince Battaglia, Head of the Electrochemical Technologies Group, manages the Electrode Architecture research group at LBNL whose main emphasis is the development and testing of battery electrodes for EV, PHEV, and HEV applications. This involves everything from developing electrode formulations with appropriate compromises in energy density and cycle life, to testing under vehicular conditions, to identifying failure modes, to predicting battery life.
Vince received his B.S. from the Johns Hopkins University in Baltimore, Maryland, and his Master’s degree in Chemical Engineering from the University of California at Berkeley. He has been working in the field of batteries since obtaining his Ph.D. in Chemical Engineering, also from the University of California at Berkeley. Upon graduating, his first professional position was with Argonne National Laboratory where he worked for 6 ½ years on two EV battery systems: LiAl/FeS2 and Li-polymer. This was followed by 7 years on assignment with the DOE in Washington, D.C. where Vince served as Technical Coordinator of Research and Development for the Office of Advanced Transportation Technologies. Vince assists the Department of Energy (DOE) on the U.S. Advanced Battery Consortium Technical Advisory Committee in the development of battery test manuals. He holds two patents and has written over 75 publications.
