Cover of Journal of Materials Chemistry A (12/2024)

The paper „In situ interphase engineering for all-solid-state Li batteries: a case study on the LiNi_0.5Mn_1.5O₄/Li_0.33La_0.55TiO₃ composite cathode guided by ab initio calculations” by Che-An Lin and co-authors has been selected as cover of Journal of Materials Chemistry A. This study results from a collaboration with the group of Prof. Shih-kang Lin (National Cheng Kung University, Taiwan).

The sinterability and interfacial stability issues in the composite cathode have been the main bottlenecks of oxide-based all-solid-state Li battery development. A suitable interfacial reaction can not only improve the sinterability by providing an additional driving force for chemical bond formation, but it can also stabilize the electrode/electrolyte interface by forming interfacial reaction products which remain stable during operation of the cell. In this work, a suitable dopant was identified through ab initio computational screening. Experimental verification was carried out by field assisted sintering technology / spark plasma sintering. The dopant was proven to induce the in situ formation of a stable protective layer between cathode and electrolyte phases.
