Abstract
A chemical process to formulate conductive ink with low sintering temperature for inkjet printing is described and shown. The application of fabricated flexible conductive film on lithium ion batteries is also described. This chemical method and composition can remove the oxidation on metallic nanoparticle surface during ink fabrication and sintering processes. Etched metallic ions in the conductive ink are reduced and particles bridged while annealing printed patterns to achieve low temperature sintering at about 350° C. The chemical process can be applied on nickel materials that are excellent current collectors for lithium ion batteries due to high chemical stability especially at high charging-discharging potential of less than 3 Volts. Thermal decomposition and chemical reduction of silver salts are two methods disclosed for particle-free silver ink. Surfactant additive further make silver film more uniform and easier to be sintered.
