SLAC and Stanford launch new joint battery center

The Department of Energy’s SLAC National Accelerator Laboratory and Stanford University have launched a new joint battery center at SLAC. It will bring together the resources and expertise of the national lab, the university and Silicon Valley to accelerate the deployment of batteries and other energy storage solutions.

To decarbonize the world’s transportation systems and electric grids, society will need to develop the capacity to store several hundred terawatt-hours of sustainably generated energy. Only about 1% of that capacity is in place today.

Filling the enormous gap between what we have and what we need is one of the biggest challenges in energy research and development. It will require that experts in chemistry, materials science, engineering and a host of other fields join forces to make batteries safer, more efficient and less costly and manufacture them more sustainably from earth-abundant materials, all on a global scale.

The SLAC-Stanford Battery Center is intended to address that challenge. It will serve as the nexus for battery research at the lab and the university, bringing together large numbers of faculty, staff scientists, students and postdoctoral researchers from SLAC and Stanford for research, education and workforce training.

Research and development at the center will span a vast range of systems – from understanding chemical reactions that store energy in electrodes to designing battery materials at the nanoscale, making and testing devices, improving manufacturing processes and finding ways to scale up those processes so they can become part of everyday life.

Longstanding collaborations between SLAC and Stanford researchers have already produced many important insights into how batteries work and how to make them smaller, lighter, safer and more powerful. These studies have used machine learning to quickly identify the most promising battery materials from hundreds made in the lab, and measured the properties of those materials and the nanoscale details of battery operation at the lab’s synchrotron X-ray facility. SLAC’s X-ray free-electron laser is available, as well, for fundamental studies of energy-related materials and processes.

SLAC and Stanford also pioneered the use of cryogenic electron microscopy (cryo-EM), a technique developed to image biology in atomic detail, to get the first clear look at finger-like growths that can degrade lithium-ion batteries and set them on fire. This technique has also been used to probe squishy layers that build up on electrodes and must be carefully managed, in research performed at the Stanford Institute for Materials and Energy Sciences (SIMES).

Jagjit Nanda, a SLAC distinguished scientist, Stanford adjunct professor and executive director of the new center, said the center will also focus on making energy storage more sustainable, for example by choosing materials that are abundant, easy to recycle and can be extracted in a way that’s less costly and produces fewer emissions.

Battery Center Director Will Chueh, an associate professor at Stanford and faculty scientist at SLAC, emphasized that the center is located in the middle of Silicon Valley’s entrepreneurial culture, two miles from the Stanford campus and a short walk away from large, world-class scientific facilities that only a national lab can provide. This generates advantages that would be impossible for any single partner to achieve, including educational and training opportunities for Stanford students and postdocs that will play an outsized role in shaping the next generation of energy researchers.

A pilot project for the center began in 2020 with two battery laboratories in SLAC’s Arrillaga Science Center where Stanford students and postdoctoral researchers have been synthesizing battery materials and evaluating devices.

The center is operated by SLAC’s Applied Energy Division and Stanford’s Precourt Energy Institute. Major funding for battery research at SLAC comes from the DOE Office of Science and Office of Energy Efficiency and Renewable Energy. SLAC’s Stanford Synchrotron Radiation Lightsource (SSRL) and Linac Coherent Light Source (LCLS) X-ray free-electron laser are DOE Office of Science user facilities.
