The ability to store large amounts of electricity from intermittent wind and solar generators is considered critical to decarbonizing our energy systems. While pumped hydro dominates bulk energy storage, lithium-ion batteries are the main source of regional grid support. Unfortunately, how grid-specific duty degrades lithium-ion batteries is not well understood, which makes business models for energy storage ventures unreliable. This project will seek to understand these degradation mechanisms and develop predictive tools that can be used for cost/benefit analysis to maximize revenue and minimize lost capacity.
