Abstract
Surface coating lithium-ion battery cathodes is a promising strategy to improve performance and mitigate cathode degradation. The coatings studied to date focus on either electronically or ionically conducting layers, which have been introduced to enhance the redox reactions of cathode particles, or oxide-based physical protection layers limiting surface degradation. Such coatings require high-temperature, time-consuming synthesis processes, along with uncertainty in the specific interactions between these coatings and lithium ions. Here, metal-phenolic network coated LiNi0.6Mn0.2Co0.2O2 (NMC) cathodes are, produced using naturally occurring polyphenols via a rapid one-step assembly, improve..
