Seed-mediated formation of multiphase zero-valent Sb nanoparticles as alloying-type anodes for sodium-ion batteries with high capacity and ultra-long durability

The CNT-supported multiphase zero-valent Sb nanoparticles in the forms of Sb, CoSb, and CoSb 2 with NC coating is synthesized by a Co-seed-mediated method. It shows high capacity, superior rate capacity, and excellent durability for sodium storage.
