The Development of Solid-state Membrane for High-Performance Solid-State Li Batteries

As a leader in the production and use of renewable energy, Canada is committed to reducing its carbon emissions by 2030 and achieving net zero by 2050. In addition, Canada will ban the sale of fuel-burning new cars and light-duty trucks from 2035. To reach this goal, it is very urgent to develop new energy storage technologies for various applications, including electric vehicles (EVs) and grid energy storage. Li-ion batteries (LIBs) are the most popular battery systems, however, the technology can further benefit from improvements in terms of safety, lifespan, and energy density. Accordingly, solid-state batteries (SSBs) have recently emerged as a promising alternative energy storage system due to their ability to overcome the safety concerns presented by the flammable liquid electrolytes used in traditional LIBs. Benefitting from the use of solid-state electrolytes, SSBs can achieve greater energy density, longer-lasting performance and enhanced safety by replacing flammable liquid electrolytes. However, the manufacturing of SSLBs with high energy density, high performances, and low cost is now the bottleneck for practical application. To realize the energy density of the SSBs, the fabrication of thin SSE membranes with high ionic conductivity, strong mechanical properties, and interfacial compatibility is key.
