Colloidal synthesis of marcasite FeS2 nanoparticles with improved electrochemical performance

Marcasite FeS2 nanoparticles were synthesized for the first time in colloidal solution via a hot-injection protocol. In comparison with the previous iron sulfides, marcasite FeS2 presents better lithium ion storage and charge–discharge performance as the anode materials in lithium ion battery application.
