Abstract:

Scientific and technological innovation accelerates the transformation of the global energy pattern toward green, low-carbon, clean, efficient, intelligent, and diversified directions. High-energy density energy storage devices are the key to realizing renewable energy consumption and promoting the electrification of terminal applications. As a next-generation high-energy density mainstream technology scheme in the industry, the all-solid-state lithium battery has attracted wide attention. This study reviews the research status of the solid electrolyte in all-solid-state lithium batteries, analyzes the main challenges faced by this kind of battery, and proposes the future development trends of this technology. Combined with literature and patent metrology, the innovation ability of an all-solid-state lithium battery is systematically analyzed herein. The results show that the R&D innovation ability of the all-solid-state lithium batteries in China is strong. In fact, more than 1000 related papers have been published, placing China on top of the rankings in this field. The Chinese Academy of Sciences topped the list with 241 papers. The statistical results of the patent results since 2015 indicate that the technology has shown a blowout development. The technical themes are mainly focused on the development and manufacturing of secondary batteries, electrode development, research and development of conductive materials, development and manufacturing of primary batteries, and research and development of special equipment for manufacturing conductive materials, among others. By far, Japan is leading in terms of the number of published patents in this field. As a suggestion, China should strengthen the protection of the intellectual property rights of this technology in the future, promote the market application of patents, and realize the commercial mass production of all solid-state lithium batteries as soon as possible to play a greater role in promoting its clean and efficient energy pattern and realizing the "double carbon" goal.
