Differential Pulse Voltammetry Analytics for SoC and SoH estimation

• Full patent application for development of an in-operando diagnostic method for characterizing state of battery.
• Conducted fast charging experiments for commercial 18650 cells with periodic in-operando pulse voltammetry.
• Estimation of key state of charge and health (SOC & SOH) indicators from experimental pulse voltammograms: Li-concentration, reaction rate constant, interfacial area
• Quantified Li-inventory loss and mechanism: particle cracking, resistive layer formation and active material loss.
