The X-CapTM electrode is made up of millions to billions of thin filaments of CNTs. Each filament is exposed to the electrolyte; which means it is actively storing charges. We produce our CNT filaments with high fiber alignment, so that electrical conductivity is very high. This enables us to get more energy in and out of the X-CapTM, which means much greater power density in volume and gravimetrically.
Initial laboratory data shows at least 200 Wh/kg using CNT filament alone; and at least 7 kW/kg. After incorporating graphene nanoribbons, we expect the specific-energy to be greater than 350 Wh/g and specific-power to be greater than 12 kW/kg.
Commercial scale machines are being designed to produce affordable X-CapsTM. Initial cost prediction will be in the $800/kWh range. As quantity increases, and using more automation, the cost should drop to the $500/kWh range. Our cost goal is $300/kWh, and can be reached once our production is optimized.
