Electroless deposition of Ni3P–Ni arrays on 3-D nickel foam as a high performance anode for lithium-ion batteries

Abstract

We successfully prepared advanced Ni₃P–Ni array electrodes for Li-ion batteries (LIBs) by electroless deposition on 3-D nickel foam. The array structure of Ni₃P–Ni can accommodate volume changes during the lithiation/de-lithiation process and promote high-rate capability because the interspaces in such structure can act as ideal volume expansion buffers. It shows excellent electrochemical performance as anode material for LIBs.
