Organic ionic plastic crystal as catholyte in positive electrode for a high energy density solid battery

Abstract (english version):

In the race for the electrification of transportation, many companies are competing to develop more efficient solid-state batteries for commercial applications. Since the landmark discovery of using polyethylene oxide (PEO) as a lithium-ion carrier for lithium metal batteries by Armand in 1978, solid-state batteries based on polymer electrolytes have been deeply scrutinized; Viable commercial applications have been provided by Blue Solutions since 2011. Despite their many advantages, such as the ability to use lithium metal as a negative electrode as well as reduced cell weight and enhanced overall safety, the use of polymer electrolytes remains limited. Additionally, the low overall ionic conductivity and transport number (t+), poor high-voltage stability, and elevated operating temperature remain obstacles for their wide implementation in electric vehicles (EVs).

In this presentation, we outline our efforts to develop a high-energy and long-life cycle NMC – Polymer Electrolyte - Li metal pouch cell. Major…
