California-based company Lyten has developed a graphene-enhanced lithium-sulfur battery for electric vehicles. The battery reportedly achieved a higher gravimetric energy density than traditional lithium-ion and solid-state technologies. Lyten is said to have has previous collaborations with the US government for military projects.
The product was named LytCell EV and was designed to deliver three times the energy density of conventional lithium-ion batteries. The company reported 900 Wh/kg, precisely three times as much as the batteries in circulation today. Lyten Sulfur Caging is the name of the technology used in LytCell batteries to unlock the performance potential of sulfur by halting the advance of polysulfide, a cycle-life compromising factor that has so far prevented the practical use of Li-S in electric vehicles battery powered. Based on testing, a LytCell prototype reportedly proved to withstand more than 1,400 cycles very well.
