Scientists at Drexel University USA may have found a way to create lithium-sulphur batteries with three times the capacity of existing batteries.


This article notes the following:
  • Drexel researchers were looking at a new type of battery—lithium-sulfur.
  • The main problem was this type of battery only lasts 2000 charge cycles, half that of existing batteries.
  • However, they found that a particular chemical phase could stop battery degradation.
  • They were then able to produce a battery that was a third of the size of existing lithium batteries.
  • It also had twice the lifespan.
  • However, the Drexel team is researching whether this new type of battery could be made using sodium-sulfur and therefore remove the need for lithium.
