Abstract

A swelling-suppressed, Si nanocrystals-embedded SiO_x nanospheres lithium storage material was prepared by graphene envelopment. The free void spaces formed between the graphene envelope and Si/SiO_x nanospheres effectively accommodated the volume changes of Si/SiO_x nanospheres during cycling, which significantly suppresses the swelling behavior and improves the capacity retention up to 200 cycles.
