- Global Key Accounts Manager (LG Energy Solution, SAMSUNG SDI, SK on, HKMC)- Sales specialist for the applications of Li-ion Batteries not only for EV, but also CE, ESS- TUBALL™ graphene nanotubes Improving battery parameters, such as energy density, charge rate, service life, and cost, is a major technological challenge that can be solved with TUBALL™ graphene nanotubes (or single wall carbon nanotubes) introduced into the recipe of lithium-ion batteries. When added to the highest energy density active materials—silicon-based for the anode and high-nickel-content for the cathode—TUBALL™ allows industry to reach energy density goals of 300 Wh/kg and 800 Wh/l and go beyond them. The best battery cells currently on the market only manage 260 Wh/kg and 700 Wh/l (21700 type).
