Ceramic nanoparticles: Overcoming the limits of battery organic materials
|
이상영 교수 UNIST The ongoing surge in demand for smart portable electronics, electric vehicles, grid-scale energy storage, and Internet of Things (IoT) has inspired the relentless pursuit of high-energy-density rechargeable batteries with electrochemical reliability. Current commercial lithium (Li)-ion batteries are composed of four major components such as cathodes, anodes, separator membranes, and electrolytes. To achieve the challenging goal mentioned above, development of advanced battery materials is urgently needed. Notably, considerable attention should be paid to organic materials (including separator membranes, binders, and electrolytes), in addition to electrode active materials. However, the existing organic materials have often failed to fulfill stringent requirements of next-generation batteries. Ceramic nanoparticles can be suggested as a promising material strategy to address this issue. This talk briefly describes opportunities and challenges of ceramic nanoparticles for their potential coupling with battery organic materials, with particular focus on post-polyolefin separators, nanocomposite coating of electrode active materials, and printable solid-state electrolytes. |
