Chemical and Biochemical Engineering Faculty Research & Creative Works

In recent years, with the severe safety problems of organic electrolytes, all-solid-state electrolytes (ASSEs) have been considered as an appealing choice to replace organic electrolytes due to their high reliability and safety. However, the uncontrolled interfacial chemical reactions between electrodes and ASSEs would lead to high interfacial resistance, which is detrimental for the battery performance. In this work, LiFePO₄ (LFP) particles were coated with ultra-thin ZrO₂ films by atomic layer deposition (ALD) and the effects of thin film coating on the electrochemical performance of lithium-ion batteries using the NASICON-type Li_1.5Al_0.5Ge_1.5(PO₄) …
