As the demand for high-energy-density storage systems grows, lithium–oxygen batteries (LOBs) have emerged as promising candidates for next-generation power sources. However, challenges such as poor cycle life, high overpotentials, and sluggish redox kinetics hinder their practical application. Now, researchers from Shandong University, led by Prof. Jun Wang and Prof. Lanling Zhao, have developed a novel electrocatalyst—1T/2H-Mo S 2 @Co 3 S 4 —featuring double heterojunctions that significantly enhance ORR/OER performance and cycling stability in LOBs.
