Improving the performance of existing cathode materials of lithium-ion batteries (LIBs) through surface modification has been proven to be an effective way to improve the performance of LIBs. However, it is a challenge to use a traditional method to prepare an effective coating film, which meets the requirements of uniformity, continuity, electrochemical stability, and strong mechanical properties. In this study, an ultrathin AlF3-Al2O3 film was coated on the surface of Li1.2Mn0.54Co0.13Ni0.13O2 (LRNMC) particles by atomic layer deposition (ALD) in a fluidized bed reactor. A cathode electrolyte …

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 Li1.5Al0.5Ge1.5(PO4) …
