Abstract

Nano-sized Sn particles were coated with Ni-P layer using an electroless deposition method and theiranodic performance was tested for lithium secondary batteries. Uniform coating layers were obtained, of which thethickness was controlled by varying the Ni2+ concentration in the plating bath. It was found that the Ni-P layer playstwo important roles in improving the anodic performance of Sn powder electrode. First, it prevents the inter-particleaggregation between Sn particles during the charge/discharge process. Second, it provides an electrical conduction path-way to the Sn particles, which allows an electrode fabrication without an addition of conductive carbon. A pseudo-1) even without conductive carbon loading.
