Graphene Slurry as Conductive Electrode Additive, 100 g/bottle, CCEAGS

Graphene is a revolutionary 2D conductive additive that is increasingly used to complement or replace traditional carbon black in battery and supercapacitor electrodes. Due to its single-atom thickness and hexagonal honeycomb lattice, it offers the highest known electrical conductivity at room temperature.

Graphene acts as a "planar bridge," creating a high-speed electron highway across the electrode surface. (1) Graphene's electron mobility is significantly higher than carbon black. This allows lithium or sodium ions to move more freely, potentially reducing charging times from hours to under 30 minutes. (2) Unlike rigid carbon additives, graphene is flexible. In anodes like Silicon (which swell by 300% during charging), graphene sheets can wrap around the particles, maintaining electrical contact even as the material expands and contracts. (3) Because graphene is so efficient, you can use much less of it (often <1% loading) compared to carbon black (3–10%). This leaves more room for active energy-storing materials.

The graphene slurry (aqueous and non-aqueous) is ready-for-use in electrode slurry without extensive dispersion proses.  

Notes: Please try to store the graphene slurry in a dry place (glovebox is the best option).
