Synthesis and Characterization of Silver Nano Wires (Ag-NWs) on MWCNTs Film Based Anode Materials for Li-Ion Batteries

Abstract With the development of microelectronics products with high density and high power, it is urgent to improve the electrical and thermal conductivity of electronic paste to achieve the new requirements of packaging materials. In this days Lithium ion batteries amazingly applied in various aspects of our life. With the wide application of lithium ion battery, the lithium ion battery efficiency requires higher technology in view point of cathodic, anodic, and electrolytes materials. In this work, a new synthesis method of Ag-MWCNTs was designed, as well as a composite of Ag nanowires combination with Multi wall carbon Nano tubes (MWCNTs) were fabricated. The MWCNTs/Sn and Ag-NWs core-shell presents remarkable structural features with enhanced conductivity, shortened the Li-ions diffusion distance, and more active area for electrochemical reactions. As a consequence, MWCNTs/Ag-NWs/Sn composite electrode exhibits improved lithium storage properties in terms of high capacity, long cycle life, and excellent rate performance. The objective of this work is based on necessity of future nano technology for lithium ion batteries; therefore, the addition of Ag-MWCNTs effectively improves the electrical, thermal, and mechanical properties of the paste, making it a promising and competitive choice for new packaging materials in the future.
