    Many researchers have made efforts to develop alternative electrode materials to replace the conventionally used graphite. Sn is one of the most attractive anode materials that can be used as an alternative to the graphite, owing to its high theoretical capacity of 991 mAhg&#8722;1. However, bulk tin anodes have exhibited poor cyclability due to crumbling under large volume expansion (up to about 300%) during Li ion insertion, which causes the pulverization and delamination of active materials from current collector during cycling.
    In this study, it is aimed to produce pyramid like nanostructured tin anodes for li-ion batteries by pulse electrodeposition to improve electrochemical reaction and cycle life of the tin anodes. To provide pyramid like nanostructured tin anodes, different peak current densities were applied when the other electrodepostion conditions were kept constant (pulse Ton = 5 ms and Toff = 5 ms). The structure of the produced anodes were investigated using SEM, XRD and EDS. Electrochemical characterization of the anodes were performed from 0.02V to 1.5V at a constant current density in CR2016 test cell.
