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