Lithium-Sulfur batteries

Up next: batteries based on how we absorb nutrients in our intestines.

"Lithium and sulfur react differently, through “a multi-electron transfer mechanism” which means that theoretically, sulfur can have a much higher capacity than lithium-ion. However, when lithium and sulfur react as the battery discharges, the sulfur turns into chain-like poly-sulphides which could enter the electrolyte as it charges and discharges, resulting in the loss of the battery’s active material."
