In the future, the pursuit of enhanced battery capacity, rapid charging capabilities, and extended cycle life will be of paramount significance, especially within the continuously expanding energy market. Lithium-Iodine batteries, owing to their inherent stability, high rate capability, and cost-effectiveness, possess the potential to emerge as a pioneering Next-Generation commercial technology. However, realizing this potential requires overcoming certain critical challenges. In this research, we delve into potential optimizations for Lithium-Iodine batteries by separately targeting improvements in the cathode and electrolyte components. It is highly likely that the ultimate solution lies in a synergistic combination of these two enhancements. Designing an efficient cathode is a multifaceted endeavor due to the intricate structure and the high solubility of active materials.
