Global Graphene Group Named R&D 100 Award Finalist

Posted By Graphene Council, Friday, January 17, 2020
Global Graphene Group (G3) was honored recently by R&D World, naming G3’sgraphene-protected lithium metal anode for rechargeable metal batteries solution (HELiX™) a finalist for the 2019 R&D100 Award. The R&D 100 Awards recognize the top 100 most technologically significant new products of the year. 

HELiX is a single-layer graphene-protected lithium metal technology making high-energy rechargeable metal batteries viable. It allows extremely low anode usage (anode/cathode ratio ≤ 10%), creating an energy density over 350 Wh/kg and 1,000 Wh/L, which yields a 60-80% improvement over current lithium-ion batteries. This offers unprecedented opportunities for advanced portable devices/electric vehicles.

HELiX is a readily available, drop-in, graphene-enabled anode solution for all types of high-energy, lithium metal batteries (e.g. advanced Li-ion, all solid-state batteries, Li-S, Li-Se, and Li-air cells). It adds immediate value to any rechargeable battery, including, but not limited to power drones, renewable energy storage systems, aerospace applications, unmanned vehicles, and electric vehicles (EVs). Additionally, due to its performance, batteries can be reduced in size by 30-40% while still providing the required energy. This provides room for other components or allows for significant reductions in size and weight.  The most promising opportunity for HELiX graphene-enabled anode solutions is inEV batteries, where it can replace incumbent (graphite) technology today and drive an accelerated adoption of EVs due to improved cost and performance. 

“Rechargeable lithium metal batteries for next-generation portable devices and EVs must meet several challenging requirements: safety, high energy density, long cycle life, and low cost.This is the end-goal laid out by nearly every EV manufacturer for the foreseeable future,” said Dr. Aruna Zhamu, VP of New Product / Process Development at G3. 

“Global Graphene Group has developed an enabling anode-protecting technology that is essential to successful operation of safe, high-energy and long-cycle-life lithium metal batteries working with liquid, quasi-solid, or solid electrolytes,” continued Dr. Zhamu.“This HELiX product has overcome the long-standing issues thus far impeding successful commercialization of all the rechargeable batteries that make use of lithium metal as the anode material. OurHELiX technology is available and offers a drop-in, scalable, facile, cost reducing improvement over current solutions. It lowers the battery cost to less than$100 US$/kWh.”

G3 developed and produces the HELiX solution in its Dayton, Ohio, facilities. G3 was named an R&D 100 winner in 2018 for its graphene-enabled silicon anode (GCATM).
