Data-driven analysis of battery formation reveals the role of electrode utilization in extending cycle life
Charging lithium-ion batteries at high currents just before they leave the factory is 30 times faster and increases battery lifespans by 50%, according to a study at the SLAC-Stanford Battery Center.
Dynamic cycling enhances battery lifetime
Consumers’ real-world stop-and-go driving of electric vehicles benefits batteries more than the steady use simulated in almost all laboratory tests of new battery designs, Stanford-SLAC study finds.
Critically assessing sodium-ion technology roadmaps and scenarios for techno-economic competitiveness against lithium-ion batteries
A thorough analysis of market and supply chain outcomes for sodium-ion batteries and their lithium-ion competitors is the first by STEER, a new Stanford and SLAC energy technology analysis program.
Group Values
As a group, we always strive to maintain a friendly environment that supports diversity and inclusion. We believe that diversity in thought and experiences greatly benefits scientific discourse and our ability to do meaningful work. Furthermore, equity in education and access is an important facet of our group’s mission. The group is always looking for creative individuals and we welcome people of all races, ethnicities, religions, gender identities and sexual orientations.
From Will Chueh: “Creativity is one of the most important ingredients to doing impactful research. Being creative means to combine diverse points of view and to draw from wide-ranging personal experiences, both scientific and non-scientific ones. Being inclusive in all facets is the key to access these diverse perspectives. I believe working with a diverse group of students, postdocs, staff and faculty will fuel your creativity and deepen the impact of the research that you do. Creativity, diversity, and inclusion come hand in hand.”
Research Mission
The availability of low-cost but intermittent renewable electricity (e.g., derived from solar and wind) underscores the grand challenge to store and dispatch energy so that it is available when and where it is needed. Redox-active materials, both organic and inorganic, promise the efficient transformation between electrical, chemical, and thermal energy, and are at the heart of carbon-neutral energy cycles.
Understanding design rules that govern materials chemistry and architecture holds the key towards rationally optimizing technologies such as batteries, fuel cells, and electrolyzers. Lithium-ion batteries, for example, are transforming mobility through electric vehicles and electricity grid through the storage of intermittent renewables. Metrics such as energy density, lifetime and safety are controlled by phenomena that span enormous length scales, from individual atoms to full systems, and times scales, from picoseconds to decades. Despite the significant progress over the past three decades, we still lack a complete understanding of how each length and time scale connects to one another, and most importantly, controls the behavior of the device.
We seek to understand and engineer redox reactions at the levels of electrons, ions, molecules, particles and devices using a bottom-up approach. Our approach integrates novel synthesis, fabrication, characterization, modeling and analytics to understand molecular pathways and interfacial structure, and to bridge fundamentals to energy storage and conversion technologies by establishing new design rules.
While our focus and approach are fundamental, The Chueh group’s work paves the way towards achieving the following goals that underpin a sustainable future:
Develop energy technologies that utilize sustainably extracted materials that enables many-fold reduction in cost floor and in emissions
Accelerate the pace of research and development to bring new energy technologies to impactful scales faster and more economically
We have four scientific themes focused on characterizing, understanding and controlling redox-active solids.
