Recent Advances in Nanoengineering of Electrode‐Electrolyte Interfaces to Realize High‐Performance Li‐Ion Batteries

A suitable interface between the electrode and electrolyte is crucial in achieving highly stable electrochemical performance for Li‐ion batteries, as facile ionic transport is required. Intriguing research and development have recently been conducted to form a stable interface between the electrode and electrolyte. Therefore, it is essential to investigate emerging knowledge and contextualize it. The nanoengineering of the electrode‐electrolyte interface has been actively researched at the electrode/electrolyte and interphase levels. This review presents and summarizes some recent advances aimed at nanoengineering approaches to build a more stable electrode‐electrolyte interface and assess the impact of each approach adopted. Furthermore, future perspectives on the feasibility and practicality of each approach will also be reviewed in detail. Finally, this review aids in projecting a more sustainable research pathway for a nanoengineered interphase design between electrode and electrolyte, which is pivotal for high‐performance, thermally stable Li‐ion batteries. A stable interface between the electrode and electrolyte is a prerequisite for the long‐term operation of Li‐ion batteries. This review investigates how the nanoengineering of the interface between electrode and electrolyte can be carried out to lower the interfacial resistance and improve the electrochemical performances. A comprehensive summary, as well as comparison/contrast, is presented for various approaches that are adopted for nanoengineering of such interface.
