A facile one-step method is developed for the direct growth of Ni3S2 nanoplates on a conductive nickel foam, which interwove together to form nest-like highly porous microstructure. When used as a binder- and conductive-agent-free electrode, the Ni3S2/Ni electrode demonstrates remarkable electrochemical performance with a superior cycling stability and a high rate capability, proving its potential applicability as a high performance anode for lithium ion batteries. The excellent electrochemical properties can be attributed to the 3-dimesional (3-D) structure of the Ni foam uniformly covered with a porous layer of Ni3S2 nanoplates. This structure provides excellent electrical contact between the active material and the current collector, a large electroactive surface area as well as well-sustained electrode integrity. The Ni3S2/Ni electrode maintains a reversible capacity of 623mAhg−1 after 150 cycles at a current density of 0.1Ag−1, and delivers a high reversible capacity of 377mAhg−1 at a high current density of 1.5Ag−1. The observed surplus capacity is found to originate from an interface storage process via a pseudocapacity-like storage mechanism.
