Lithium is expensive, environmentally detrimental, and extremely difficult to dispose of due to the numerous rare earth and chemicals within lithium-ion battery cells. This is where graphene comes in, more specifically $GMG.V’s graphene. But what makes their graphene so different from competitors? Well, they produce it directly from natural gas, allowing them to retain battery-grade purity and reduce dependence on supply chain difficulties/price fluctuations. This vertical integration will allow $GMG.V to continue being a leader in the space, especially as they inch closer to their graphene battery production.
More recently, $GMG.V released an update on their graphene batteries, and all I can say is that the development looks good.
- Energy density has increased to 290-310 Wh/kg, an increase of 93% since the last update on June 22, 2021. Power density has also increased 33% since then to around 9,350 W/kg.
- Work was conducted across the entire cell design to optimize performance, and at this rate of improvement, the coin cells aren’t too far away from initial customer sales and use.
- The estimated time to fully charge a phone went from the previous 1-5 minutes to 3 minutes.

These results make their batteries one of the leading graphene batteries in terms of energy/power density and charging speed. Charging speed is going to be a key player in graphene batteries as it reduces the downtime needed to get back into action by a significant percentage over lithium-ion. Overall, with these promising results and production around the corner, there could be significant potential for this to become a market leader in graphene batteries.
