Graphene battery storage:

Sustainability Problem: 

Currently used batteries such as lithium-ion and lead acid batteries take hours to charge and have short lifespan for charging and discharging. They can also be harmful to the environment.  Lithium-ion batteries are unstable and can explode and cause fire.

Technology:

Graphene battery storage is under production at Graphenano, a Spanish based company that develops diffierent technologies using graphene. Graphene is a monolayer carbon lattice that is harder than diamond. These new battery  offers much higher energy density than Lithium-ion (1000 Wh/kg vs. 200Wh/kg on a Tesla Model S), has no fire or explosion danger unlike Li-ion, and charges in minutes, lasts longer , and 3 to 5 times smaller than Li-ion battery.

These battery can be used for electric bikes, electric motorcycles, and to store solar energy. Grabat company shows advantages of graphene-based battery over other batteries:

Grabat say that their battery chemistry will drastically decrease charge times

Grabat suggest that the current energy density of their battery chemistry is far ahead of the competition

Stakeholders:

  • Graphenano, Grabat, Chint companies
  • bicyclists, motorcycle drivers
  • residential solar system owners
  • researchers
  • government

Implementation: 

  1. More media exposure to encourage attractiveness  of graphene-based battery to the public.
  2. Full production of the battery will be underway by October.
  3. Continuous research to improve this battery to lower its cost.
