Eco-efficient synthesis route of carbon-encapsulated transition metal phosphide with improved cycle stability for lithium-ion batteries

An eco-efficient synthesis route is developed to prepare carbon-encapsulated Ni3P nanoparticles embedded in carbon nanosheets as a cycling-stable anode material for lithium ion batteries. The green method is achieved by calcining the precursor of intercalated sodium dodecyl phosphate/Ni(OH)(2), and is readily extended to prepare the transition metal sulphide by altering the intercalated surfactant.
