CONDUCTIVE ADDITIVE
Upgrade your electrodes with eGraphene — 52× more conductive than carbon black and up to 30× cheaper than SWCNTs, for high-performance cathodes and anodes.
Today’s conductive additives force a trade-off: Carbon black is easy to use but has low conductivity, limiting electrode performance and energy density. SWCNTs enable high-performance cells but come with a high cost per kWh and complex processing. Cell manufacturers need a conductive additive that delivers high conductivity without cost or processing penalties — scalable, stable, and easy to integrate.
NMC & LFP Cathodes
High-performance cathodes need conductive networks that outperform carbon black in conductivity while avoiding the high material cost and processing complexity of SWCNTs.
Si, LTO & SiOx Anodes
Advanced anodes require high-conductivity networks — with the added need for pathways that stay intact during volume changes and SEI growth to ensure long-term cycling stability.
INTRODUCING
eGRAPHENE
eGraphene is a few-layer, electrochemically exfoliated and functionalized graphene made through a patented water-based process and supplied as ready-to-use formulations. They establish a highly efficient conductive network in cathodes and anodes alike, delivering performance and cost benefits without the trade-offs of carbon black or CNTs — a true next-generation conductive additive.

CATHODE
PERFORMANCE
LFP cathodes vs. Carbon Black
By adding only 0,1% eGraphene, you can improve electrode conductivity and, thus, potentially reduce the amount of carbon black to achieve higher active material loadings.
eGraphene impact:
3x
More conductive LFP-cathode with 0.1% eGraphene added to 2% CB (SuperC P65)
LFP cathodes compared to SWCNTs
eGraphene delivers SWCNT-performance at higher loadings but lower prices - a valid alternative for single-source supply chains.
eGraphene impact:
30x
Cheaper than SWCNTs but close to CNT performance, despite being 2D flakes
NMC cathodes vs. Carbon Black
eGraphene offers faster charging and better cycling stability at lower loadings than carbon black.
eGraphene impact:
3x
Improved charging speed by adding 1% eGraphene to 2% CB in NMC-cathodes (vs. 3% CB)

ANODE
PERFORMANCE
Conductivity at
Si-Anodes
eGraphene can enhance conductivity in Si-rich anodes at all states of charge when replacing graphite.
eGraphene impact:
50%
More conductive Si-rich anode with eGraphene compared to the reference with base Graphite content
Cycling stability & FCE at Si-Anodes
eGraphene can improve cycling stability and first cycle efficiency (e.g., at Si-rich graphite anodes).
eGraphene impact:
3x
Better cycling stability and 30% better first cycle efficiency; the number of cycles required to reach >99% CE decreased from 7 to 5
Charging speeds of LTO anodes
eGraphene can enable LTO anodes with even higher cycling speeds (compared to carbon black).
eGraphene impact:
3x
Increased charging rate for LTO anode (5 min to 80% vs. 15min) combined with ~8% capacity increase

PROCESSING
Easy-to-use dispersions or pastes
eGraphene is available as a drop-in formulation in various solvents (NMP, water, DMF, DMSO) — completely surfactant-free thanks to in-situ functionalization. This enables stable, low-viscosity slurries without any pre- or post-processing. Unlike powders, eGraphene poses no health risks during handling or application.
