Graphene Aluminium Ion

Graphene cathode and aluminium anode, high charge rate battery technology. The research by Professor Gao Chao at Zhejiang University has the following claims:

  • 91% of its original capacity after 250,000 cycles.
  • Fully charged in 1.1 seconds.
  • Wide operating temperature range -40 to 120°C
  • It can be folded.
  • Does not explode when exposed to fire.

However, there are a number of challenges:

  • Low gravimetric and volumetric energy density.
  • High cost – due to electrolyte used.
