Rich Interfaces in C/SiOx Nanocomposite Anodes In article number 2200303, Yutthanakon Kanaphan, Annop Klamchuen, Nonglak Meethong, and co-workers reveal the roles of interface in C/SiOx nanocomposite anodes for Li-ion batteries (LIBs) by experiments and first-principles calculations. Rich interfaces between carbon and SiOx provide additional storage pathways for Li+ enabling excellent electrochemical properties and long-life LIBs.
