Lithium-sulphur batteries may well be the next generation of power cells that we use in our electric vehicles — if scientists can get them to last longer. And that’s exactly what a team of researchers at the University of Michigan has tried to accomplish with the development of a 1,000-cycle battery that could quintuple EV range. What’s the potential of lithium-sulfur batteries? Lithium-sulfur (Li-S) batteries have a series of advantages over their lithium-ion (Li-ion) counterparts:  The theoretical energy density of a lithium-sulfur cell is 2,510Wh/kg, compared to a lithium-ion’s 300Wh/kg. This means that Li-S batteries can store two to five…
