The solution we offer based on carbon nanomaterials affects the structural characteristics of the active mass of the electrode.

If our carbon-based materials has been added to the Negative & Positive Active Material (NAM & PAM) during paste preparation in a variety of forms including MWNT and exfoliated graphite based graphene structures, when incorporated at 0.1-0,8% w.r.t. lead oxide, carbon increases the charge acceptance of a battery by more than 200% but at the cost of paste rheology and paste density. Reductions in paste density directly lead to increased active material adhesion to the grids, increased battery capacity with no requires of higher active material masses to reach specification, and sufficient cold-cranking performance.

New paste processing machinery is often required to overcome some of the issues brought on by high carbon loading. Our proposed carbon-based materials are easily incorporated into battery pastes as a concentrated, pourable fluid or paste. The fluid or paste replaces a portion of the water used during the paste mixing process, requiring no alteration to existing industrial production lines. When combined with traditional paste ingredients (lead oxide, expander, fiber, water, and acid) at 0.36% w.r.t lead, our new advanced materials offer prolonged increases in charge acceptance and more efficient battery usage with no detrimental effect to paste rheology or Reserve Capacity (RC), and an augmented Cold-Cranking Ability (CCA)
