This paper presents a hybrid state-of-charge (SOC) and state-of-health (SOH) estimation technique for lithium-ion batteries according to surface temperature variation (STV). The hybrid approach uses an adaptive observer to estimate the SOH while an extended Kalman filter (EKF) is used to predict the SOC. Unlike other estimation …
Improving interfacial properties of metallic Li is paramount to achieve a degree of control on the evolution of its reactive surface and SEI layer. Potential reinforcement of Li metal surfaces via preliminary exposure to reactive gases (e.g. N 2, O 2), yielding direct formation of ceramic compounds with Li +-conducting properties, could …
