The longevity of lithium-ion batteries (LIBs) is greatly affected by ageing. Therefore, models are required to accurately describe their degradation behaviour. Given the complex processes involved in battery ageing [1], identifying suitable parameters is a significant challenge in model development [2]. This study focuses on the loss of cyclable lithium due to the binding of […]

Layered oxide cathodes have attracted wide research interest due to their controllable synthesis, tuneability, and high energy density in sodium-ion batteries (SIBs). However, in layered oxide cathodes, capacity retention is unsatisfactory due to structural changes, and the severity of capacity fading increases at higher voltages. Chemical heterogeneity and concentration gradient lead to the co-existence of […]

This Poster presents an online estimation method for Open Circuit Voltage (OCV) using an Extended Kalman Filter (EKF) and a self-evaluation criterion to improve State of Charge (SoC) estimation accuracy in LiFePO₄ (LFP) batteries. Traditional OCV estimation relies on offline measurements, making real-time applications challenging. To address this, the proposed approach continuously adjusts OCV values […]
