after 1,000 cycles at a current rate of 1.0 A g . Yu et al. encapsulated Sb nanoparticles derived from MOFs in
-1
hollow carbon and titanium dioxide nanotubes (Sb/CTHNs) to suppress volume expansion and enhance Li
+
diffusion [Figure 8C] . The Sb/CTHNs provide a large surface area and pathways for Li-ion diffusion and
[80]
electron transport. The robust hollow structure accommodated volume expansion during the alloying/
dealloying process, resulting in a stable SEI layer and a high rate capability of 374.1 mAh g at a current rate
-1
of 5.0 A g . Yang et al. fabricated a CoSb nanocomposite anchored on Swiss-cheese-like nitrogen-doped
-1
porous carbon (CS/NPC), which delivered stability and a high rate capability [Figure 8D] . The specific
[81]
structure contributed to enhanced electronic conductivity, a shorter ion-diffusion distance, and suppressed
Sb volume changes during repeated cycling. The CS/NPC anode exhibited a high rate capability of
343 mAh g at a current rate of 10 A g . The strong metal-N-C bonds formed by the doped heteroatoms

provided sufficient active sites for Li ions and strengthened interfacial adhesion between the active materials
