Graphene Manufacturing Group Ltd. Dec. 9 announced that the pilot production and testing plant for its graphene aluminum-ion batteries is now operational and the first coin cells of these potential lithium-ion battery competitors have been manufactured.

"The commissioning of our battery pilot plant is an important milestone for GMG," said Managing Director and CEO of Graphene Manufacturing Group Craig Nicol. "Not only will it allow us to develop, manufacture and test our own G+AI Battery coin cell and subsequently pouch packs in-house, it will also enable the company to accelerate the commercial development of our G+AI Batteries, work with future customers and further build on our internal expertise."

Based out of Australia, Graphene Manufacturing Group is a clean-tech company that, instead of mining graphite, produces graphene by cracking methane. Using a proprietary process, GMG has devised a method to produce high-quality, low-cost, scalable, tunable, and no or low contaminant graphene.

While GMG graphene can be used for a wide range of industries, the company's initial focus has been on developing applications for energy saving and energy storage solutions, and with a pilot plant for producing its graphene aluminum-ion batteries, its vision is coming to fruition.

So, the graphene is manufactured from natural gas. How do the greenies square this with NO fossil fuels?

Also, energy density is touted 1000 Wh/l as compared to 250 wh/l  for Li ion batteries, both are small fractions of diesel which is about 10200 Wh/kg. That still makes it a loser.
