1. Introduction Acetonitrile (AN) is a promising organic solvent for lithium-ion battery (LIB) electrolytes from the viewpoint of fast-charging and extremely low temperature performance due to its low viscosity and high relative dielectric constant. Asahi Kasei succeeded in developing an AN-containing electrolyte for LIBs by deriving the appropriate combination of additives that suppress the reduction […]

The impedance of the battery contains rich information about the internal structure and health state of a battery. Existing impedance-based state-of-health (SOH) estimation methods often rely on machine-learning algorithms to capture the complex relationship between the impedance and the SOH. In this study, for the first time, a novel hybrid SOH estimation method is proposed, […]
