Lithium sulfur (Li-S) battery has higher theoretical and experimental specific energy. There- fore, Li-S battery is the most capable energy storage option for electrical vehicles and power grid. However, it has life cycle issue to prevent its usage in electrical vehicles. Li-S battery need to im- prove life cycle issue in order to work with current battery applications. Li-S battery has complex chemistry and process to discharge and charge Li-S cell. The cost and manufacturing process of Li-S batteries will be one of the biggest challenge for commercial transformation from research and development stage. The Oxis Energy is developing Li-S battery for past 10 years and they have goal price US$250/kWh by 2020 with high volumes and more cheaper compare to lithium-ion battery.
