Lithium-ion batteries need to be stored and operated in 'Goldilocks' conditions — not too hot, and not too cold. Our research and development portfolio challenges the electrochemical energy storage status quo by changing temperature extremes from a liability into a resource. Distinct programs are focused on using temperature as a tool to understand ion mobility and bonding, and making electrochemical energy storage work at higher temperatures. A unifying theme is the research, development, and deployment of enabling hardware and processes. This integrated platform allows us to access new materials and phases (leading to higher cell voltages and capacities using abundant materials, and enable new experimental approaches), explain dynamic performance (via our existing and expanding suite of in-situ and operando tools and techniques) and discover new reaction / failure mechanisms (via accelerated lifetime testing), all while providing a complex, welcoming, and challenging training environment.
