High Storage
Capacity
The high storage capacity of G3 S/graphene composite (up to 900 mAh/g) allows the battery to hold more charge and last longer between charging.
Drop In
Solution
Higher capacity results in higher energy density (>400 Wh/kg) and thus smaller battery form factors.
Improve Cycle
Efficiency
G3 S/graphene composite has an exceptional cycle efficiency even with its high capacity, which mean battery lifetime is not sacrificed.
Cost
Cost available cathode solution available today.
Graphene Conductive Additive
High Rate
Capability
With graphene dispersion additive for cathode, the energy density can improve as high as 20% at high rates.
Low Cost
Upgrade
Most conductive additives can be replaced by as low as 0.005% graphene to obtain equal or better rate performance.
Drop-In
Solution(s)
Every material we develop is geared toward compatibility with existing processes to ease adoption.
Compatibility
Compatible with all commonly used cathode materials.
Graphene-Al Enabled Current Collector for High Voltage Cathode
Enhanced Corrosion Resistance for High Voltage
Graphene prevents Al foil from corroding in the presence of electrolyte solution and moisture impurity.
Drop-In
Solution
Compatible with existing processes to ease adoption.
Improved
Adhesion
A thin graphene layer over an Al foil offers up to 30% higher bonding strength with the cathode material in contrast to bare Al surface.
Compatibility
Graphene layer can lower battery impedance up to 25%, improving rate performance.
