NiSb alloy hollow nanospheres (HNSs) obtained by galvanic replacement were firstly applied as anode materials for lithium ion batteries, giving the best electrochemical performances for NiSb alloy materials so far with a high reversible capacity of 420 mA h g −1 after 50 cycles, close to its theoretical capacity (446 mA h g −1 ).
