- Abstract
- We have prepared a primary film battery which shows improved shelf life and long-term stability. We tried to optimize a multi-layered packaging film by considering gas permeability, chemical affinity, and film thickness. We also optimized conducting layer thickness, cathode/anode thickness and their compositions taking N/P ratio into account. We introduced a variety of hydrogel polymers, newly developed electrolyte solutions, and novel separators to enhance the ionic conductivity value of gel-type polymer electrolyte/separator system for peak power and high power property.
