Ionic liquid are promising electrolytes (ILE) for high-voltage lithium metal batteries because of their wide electrochemical stability windows, high thermal stability, and non-flammability. [1]. However, their high viscosity and strong ion pairing often suppress Li⁺ mobility and limit ionic conductivity [2]. Although co-solvent addition can improve transport properties, the effects of lithium salt concentration and […]

Through-plane thermal conductivity of a lithium-ion battery changes significantly throughout its life, but the magnitude of change is highly dependent on the ageing conditions and loads applied to the cell. Accurately accounting for the evolution of thermal properties is essential for predicting cell temperature rise under different operating conditions. Neglecting changes in thermal properties during […]

This poster presents an investigation into the degradation behavior and health prediction of second-life LiFePO₄/graphite batteries, combining experimental analysis with data-driven modeling. Retired electric vehicle batteries typically retain 70–80% state of health (SoH), making them suitable for repurposing in stationary energy storage applications until they reach approximately 60% SoH. The study aims to better understand […]
