TUBALLBATT H2O

Request

TUBALL™ BATT H2O is an ultrafine TUBALL™ nanotube dispersion in water for high-energy Si anodes. It creates a robust network inside the Si anode and solves the problem of its degradation, allowing Li-ion battery makers to use record high quantities of silicon in the recipes of their cells for the first time and reach the desired energy density targets, as well as unlocking fast-charging capabilities.
