| Grain size, and MWCNT content in the electrolyte of nanocrystalline Sn-Ni/MWCNT composite deposits produced from a solution containing nickel chloride and tin chloride at constant electrodeposition conditions (pulse on-time Ton at 2.5 ms and pulse off-time Toff at 7.5 ms) but with different peak current densities were investigated. The structure of the electroplated thin film Sn-Ni/MWCNTs composite electrode is investigated by X-ray diffraction, scanning electron microscopy. Galvanostatic charge/discharge measurements were performed in the assembled CR2016 cells designed by using anode composite material produced by pulse electro co-deposition. These cells discharge capacities were cyclically tested by a battery tester at a constant current in voltage range between 0.02 and 1.5 V. The electrochemical results showed that the increase in the discharge capacity of the assembled cell was produced when compared with conventionally used graphite lithium-ion batteries. |
