However, the liquid electrolyte was still utilized in most common lithium batteries. If one continues to work on the high capacity batteries of the same kind, it would eventually cause the safety concern for the batteries, including leaking, swelling, heating, smoking, firing, and exploding. It is apparent that the requirement for the stability and safety issues becomes more important, if the battery material technologies were focused on the high capacity end. An all-solid-state secondary battery is a battery which relies on the solid-state electrolytes to replace the common organic electrolytes. By fully solidify the electrolyte inside the battery structure, one can solve the safety problem of the liquid lithium batteries. Therefore, the development on the solid-state electrolyte becomes the key issue. The challenge on the development to tackle this problem is rather tough because the electrolyte needs to possess both electronic insulating properties and sufficient ionic conductivity. This project proposes a new concept, namely, “hybrid system,” to synthesize the solid-state electrolyte by using the solid/gel/liquid-state electrolytes or the solid/gel-state electrolytes. In order to efficiently develop the solid-state electrolyte thin films for different hybrid systems, we intend to collaborate with the domestic academic research groups who have some experience on the materials synthesis. Subsequently, these hybrid systems can be combined with our equipment and processes to accelerate the development of the all-solid-state secondary batteries under R&D in our Institute.電致色變元件膠態/固態電解質混成系統氧化鎳三氧化鎢Electrochromic deviceGel/solid-state electrolyteHybrid systemNiOWO3
