 A new type of carbon-based material has been developed that can serve as a highly efficient and durable cathode for lithium oxygen, LIO2, batteries. This material consists of a graphing-like structure with many topological defects, which allows it to have excellent electrochemical stability and a large capacity. It also has the ability to catalyze the decomposition of amorphously-202, leading to better battery performance. Additionally, this material does not require any additional catalysts or mediators, making it more cost-effective than other materials.
