Abstract

Abstract : Yolk/double‐shelled SiOx @TiO2 @C nanospheres with different voids were successfully prepared, and the regulation of SiOx yolk was achieved by changing the etching time. The etching time of SiOx yolk affects the morphology and electrochemical performance of SiOx @TiO2 @C. The dial represents the etching time of SiOx yolk in NaOH solution and the brightness of the Chinese red lantern represents the electrochemical performance of the composites. When the etching time is 60 min, SiOx @TiO2 @C with 30 nm void exhibits remarkable performance as an anode for lithium–ion batteries. More information can be found in the Full Paper by G. Zhou et al. on page 2654 .
