And backed with 20 years of ionic materials research and experience in working closely with leading companies, the Battery Research and Innovation Hub is poised to bring this next generation battery technology to the commercial world.
As the electric vehicle market grows, so too does the need for electric vehicle batteries that are safer, fast charging and longer lasting.
Solid-state batteries are one class of next-generation batteries that are showing huge potential to address these needs by offering a drastic change to the battery components that are used in current technology.
As opposed to the liquid electrolytes used in more common battery types, solid-state batteries use thermally stable solid electrolytes as ion conductors. Solid electrolytes, such as solid polymer electrolytes (PILBLOCs), are non-flammable, non-fluid and therefore a low risk of catching and spreading fire – offering a much safer energy-storage option than lithium-ion batteries in which flammable liquid electrolytes are being used.
And although researchers have reported the small-scale demonstration of solid-state batteries – for example using coin cells – the fabrication of large-scale solid-state batteries with practical performance has proven challenging.
However, at the world-class Battery Research and Innovation Hub our unique capabilities to complete materials research for solid-state batteries from proof of concept to pilot-scale production, puts us in good stead to deliver this next generation battery technology to market.
Our researchers can synthesise and characterise of ionic materials, integrate ionic materials into batteries, evaluate battery performance and failure, and design the scale-up of battery manufacturing processes.
Our world-class research group has over 20 years of experience in the study of ionic materials and a proven track record of industry collaborations in the battery field – making the Battery Research and Innovation Hub well placed to help bring solid-state batteries to the commercial market.
Solid electrolytes studied for solid state batteries include solid polymer electrolytes, oxide solid electrolytes, sulphide solid electrolytes, and their composites.
Benefits: Solid-state batteries can be operated at a wide range of temperatures, especially at high temperatures that lithium-ion batteries cannot tolerate. Some solid electrolytes that can transfer ions at a faster rate than conventional liquid electrolytes.
Applications: Electric vehicles, energy-storage systems, consumer electronics such as laptops and smartphones, niche applications such as batteries that can be operated at high temperatures, i.e. 60–200 °C, aerospace.
