TUBALL™ BATT
TUBALL™ FOR ENERGY STORAGE
TUBALL™ BATT is a solution designed for easy integration of TUBALL™ Graphene Nanotubes into electrode formulations during battery production.
TUBALL™ BATT provides a complete or partial replacement for carbon black in battery electrodes and can replace a few percent of carbon black with just 0.03–0.1% TUBALL™ Graphene Nanotubes.
TUBALL™ Graphene Nanotubes create 3D conductive networks between active material particles at very low concentrations. These nanotubes reinforce the electrode structure and improve its mechanical stability during charge/discharge. TUBALL™ enhances adhesion by establishing strong bonds between particles, reducing the amount of binder needed.
