Electrochem Seminar- Materials Design Principles of Amorphous Cathode Coatings for Lithium-Ion Batteries
Abstract
Cathode surface coatings present one of the most popular and effective solutions to suppress cathode degradation and improve cycling performance of lithium-ion batteries (LIBs). In this seminar, I will talk about our recent work in developing materials design principles governing amorphous cathode coating selections for LIBs using an extensive high-throughput computational approach. Combining the screening results and detailed ionic diffusion analysis of the selected cathode coatings, I will present several promising coating candidates and summarize the general selection guidelines of amorphous cathode coatings for LIBs. Our findings can be expanded as a universal strategy to stabilize Li metal anodes and solid-state electrolyte.

Jianli received his M.S. in Chemical Engineering at Rutgers University, where he worked in Prof. Alexander Neimark’s group in modeling interactions of nanoparticles with polymeric systems. He then completed his Ph.D. with Prof. Kesong Yang from the University of California, San Diego in 2018. His Ph.D. work involved modeling oxide heterostructures and grain boundary structures. His current research concerns a variety of thermodynamic, kinetic, and mechanic phenomena generally observed in Li-ion batteries and searches for new functional materials and design principles using atomistic simulations, data science and machine learning.
