From the past, productivity improvement has been a problem to be solved, and various methods have been continuously developed. Recently, the demand for electric vehicles has increased along with the domestic and international environmental policies. Researches on the electrode production facilities have been actively conducted to increase the productivity of secondary batteries. Dispensers required for bonding the separator of the secondary battery, the cathode material and the anode material are also increasing in demand. The dispensers that spray a certain amount of adhesive quickly contribute to productivity improvement. However, Piezo type, which is currently being developed and used widely, has a higher performance than some industry, and its more expensive. In this study, we design a dispenser with lower performance than the conventional piezo type and lower the unit price and analyze the results.

The purpose of this review paper is to highlight recent efforts and achievements to realize high productivity of micro/nano structure fabrication processes and feasible applications. Due to development in micro/nano fabrication processes, demands on micro/nano related applications are increasing rapidly in various fields. To meet requirements, fabrication process must have high production yield and be automated. Also, fabricated micro/nano structures are expressed on large area substrate. So, it is timely and appropriate to move forward to a new epoch by researching more robust and high throughput fabrication methods, large area fabrication techniques, and new applications. In this review paper, we present a series of recent achievements to overcome some of the limitations in productivity and product size of current fabrication processes, such as photolithography and imprinting lithography. For potential applications, transparent metal electrode, large size optical film, bus wire for narrow bezel, and water collecting surface, are briefly described to expand the application field from the well-known.
