Graphene Aluminum Ultra Fast Charging Batteries

What Is Graphene?

Graphene is a thin layer made from carbon, which has a hexagonal arrangement of the carbon atoms. This has the atoms arranged in a honeycomb lattice configuration. At the nano level, graphene exhibits certain properties that make it a good application for conducting electricity and absorbing thermal energy.

Aluminum-Ion Battery

When charging batteries or energy storage devices, the power density gives an indication of how quickly a cell can charge and discharge. Lithium-ion batteries have a power density between 250–700 W/kg. An aluminum-ion battery is 7,000 W/kg. This puts the level of aluminum-ion with that of ultra capacitors which have a power density of 12,000–14,000 W/kg. Capacitors are electrical components that store a charge, which can then be distributed to provide power.

The Challenges Ahead

The most anticipated application for batteries is for powering devices. Charge times are often long and if the user has no backup battery, they are just going to have to wait. Higher energy density batteries with faster charging times are going to be a game changer in that regard, every time this issue comes up. The question is will al-ion batteries be up for that challenge.

Final Thoughts

Al-ion batteries are still a prototype in mid-2021, not a commercial product like Tesla’s li-ion batteries. These batteries are also not yet used in any actual application other than for research.

  • Greener alternative to li-ion batteries
  • Much more efficient in heat conduction
  • Faster charging times
