The increased demand for lithium-ion batteries (LIBs), and the stain this will place on supply, has sparked significant interest in sodium-ion batteries (NIBs). Sodium is cheaper and more abundant than lithium, making NIBs a more sustainable option for certain applications. This thesis aims to explore a low energy intensity synthesis method for Na-ion cathode materials while investigating the use of environmentally friendly binders derived from natural polymers. The focus is on Na2/3Ni1/3Mn2/3O2 (NNM), a strong candidate for Na-ion battery cathodes due to its high theoretical capacity of 173 mAh g-1 and operating voltage around 3.7 V Na+/Na. Notably, the research addresses the challenges of synthesizing the low-temperature phase of NNM at 550 °C using an emergent method known as biotemplating, which employs water-soluble, naturally occurring polymers to inhibit recrystallization during initial calcination stages. This work advances the understanding and application of the biotemplating method, ultimately contributing to more sustainable practices in the synthesis of Na-ion cathode materials.
