Using low-cost graphene in the cathodes enhances charge rates and energy density in batteries, making this technology a game-changer for the industry. This approach helps cut lithium-ion battery charging times in half and reduces manufacturing costs by 12%. CEO Joe Stevenson is leading this startup.
Graphene-based batteries represent a revolutionary leap forward, addressing many of the shortcomings of lithium-ion batteries. These batteries conduct electricity much faster than conventional battery materials, offer a higher energy density, and charge faster because of Graphene.
Battery Technology Readiness Level The battery technology readiness level (“BTRL”) of the Graphene Aluminium-Ion technology remains at Level 4 (see Figure 4). GMG is currently optimizing electrochemical behaviour for pouch cells via ongoing laboratory experimentation.
Please see charging and discharging curve typical of the GMG’s Graphene Aluminium-Ion Battery 1000 mAh cell in Figure 2 showing a nominal voltage of 1.7 volts.
The graphene coating reduces degraded battery performance over time and enhances chemical stability. It limits solid electrolyte interphase (SEI) impedance growth and improves safety and temperature stability.
Volexion developed a drop-in graphene encapsulation technology for lithium-ion cathode materials to address the main issues of Li-ion batteries. This technology enhances the comprehensive performance of batteries, achieving over 30% energy density increase compared to the current technologies.
