Graphene ultracap modules in energy storage systems
With the sharp rise in renewable energies, the need to store unsteady energy sources such as solar and wind cleanly and highly efficiently, and to release the electrical energy just as quickly when required, is increasing. Energy storage systems (ESS) have therefore become a key factor in stabilizing our energy supply grids.
Other ESS applications
- Uninterruptible power supply (hospitals, data centers, etc.)
- Peak shaving (day/night power management)
- Load balancing in power supply networks
Graphene hybrid supercapacitors vs lithium-ion storage
Energy storage systems based on lithium-ion are still the standard in many applications today. However, technical developments in the energy storage market have made considerable progress in recent years. This includes the use of graphene/acid and graphene hybrids as positive electrodes for supercapacitors. As a result, hybrid supercaps now achieve a comparable energy density and also offer other decisive advantages:
- No degradation as with chemical electrolytes
- Significantly longer service life
- Faster charging/discharging
- Higher temperature tolerance
- Greater safety (no "thermal runaway")
- Recyclability
CAPCOMP GmbH is in close contact with manufacturers of such energy storage solutions and will include them in its product range in future.
