This project aims to advance the development of long-lasting sustainable batteries by innovating new polymer electrolyte additives and incorporating new imaging techniques. The use of polymer additives is one of the most economical approaches for improving battery performance. However, polymers prepared using modern techniques have a broad range of physical properties and chemical structures, obscuring how their design principles are understood. This project expects to tackle these challenges by developing a new method for producing truly discrete new polymers. The expected outcomes are new knowledge in polymer electrolytes and imaging which will result in more efficient and reliable batteries. This provides significant benefits to polymer science and Australia’s renewable battery industry.
