Preparation of a Ni 3 Sn 2 alloy-type anode embedded in carbon nanofibers by electrospinning for lithium-ion batteries

Ni 3 Sn 2 intermetallic alloy encapsulated in a carbon nanofiber matrix (Ni 3 Sn 2 @CNF) was obtained by electrospinning. The Ni 3 Sn 2 @CNF anode produced a high initial discharge capacity of ∼1300 mA h g −1 , later retaining ∼350 mA h g −1 after 100 cycles.
