Abstract
Dual-confined porous Si@c-ZIF@carbon nanofibers (Si@c-ZIF@CNFs) are fabricated that possess excellent antioxidant capacity, high surface area and abundant pores, which enhances conductivity, relieves volume expansion and facilitates electrolyte penetration during cycling. When evaluated as self-supporting anodes for lithium-ion batteries, the Si@c-ZIF@CNFs exhibit excellent cycling and rate performance.
