Bor-Rong (Hypo)’s work at Idaho National Laboratory (INL) focuses on building techniques for identifying aging phenomena in fast-charging Lithium-ion batteries in electric vehicles. These techniques pinpoint where, when, and why aging happens in batteries at an early stage during operation. Hypo’s research will significantly accelerate the development cycles for more durable Li batteries, a critical key for promoting the deployment of electric vehicles and reducing greenhouse gas emissions.
