Graded Graphene Oxide for Battery Materials

Graded Graphene Oxide (GGO) is an aqueous drop-in graphene additive designed to improve the performance, stability, and processability of advanced battery materials, especially silicon-based anodes for lithium-ion batteries. The additive can be added directly to existing manufacturing processes and disperses easily in electrode slurry preparation.

However, silicon anodes can expand strongly during charge and discharge cycles, causing cracking, delamination, and reduced battery lifetime. Danish Graphene’s drop-in Battery additive is designed to address these challenges by improving dispersion stability, electrode integrity, and long-term cycling performance.

The additive can be integrated directly into existing electrode slurry preparation processes without additional stabilizers or major reformulation. It disperses uniformly, maintains a high concentration of active material, and helps prevent agglomeration during electrode casting. In evaluations with five different silicon anode manufacturers, the product showed positive effects on silicon anode performance. Compared with conventional carbon nanotube additives, it offers easier handling, improved processing, and strong performance in demanding silicon anode systems.

The product is manufactured using a renewable electrochemical production method mainly relying on water and sustainable energy, supporting more sustainable battery material development.
