Battery research worldwide is focused on developing next-generation batteries, and the lithium metal battery has emerged as a promising candidate. This advanced battery design replaces the conventional graphite anode with a lightweight lithium metal anode, offering high capacity and a low oxidation-reduction potential. A high-nickel cathode with increased nickel content and a lithium metal anode are required to achieve high-energy-density lithium batteries.<br/>However, rapid capacity degradation caused by dendrite formation due to the deposition of transition metals from the cathode onto the lithium metal and the formation of an unstable solid electrolyte interface (SEI) layer during battery operation is challenging. A well-designed functional separator approach can effectively mitigate these issues and improves the performance of the lithium metal battery by minimizing the byproducts of side reactions. This study demonstrates the crucial importance of restricting the movement of transition metal ions to the lithium metal anode, contributing to enhanced operational performance and stability of the lithium metal battery.
