Directa Plus announces “fantastic achievement” with partner NexTech’s graphene-enhanced prototype battery

Directa Plus, which has recently signed a non-binding memorandum of understanding with lithium sulphur batteries company NexTech Batteries, has announced that using its G+ pristine graphene nanoplatelets, NexTech managed to achieve more than 400 watt-hours per kilogram in a practical system, “the holy grail” for many battery applications.

NexTech produced several prototypes using its proprietary cathode and electrolyte materials producing 410Wh/kg of specific energy at a weight only slightly below 30 grams. For comparison, standard lithium-ion batteries have an energy density of 100-265 Wh/kg.
