In a recent interview on the Cleanerwatt Youtube Channel (67.7K subs), the CEO of Graphene Manufacturing Group (GMG.v GMGMF), Craig Nicol talked about the company and the recent improvements that they have made in their battery technology.
These improvements include greatly increasing the energy and power density of their latest generation of Graphene A-I batteries.
Nicol also shared that there have been no differences in how the battery operates at 0° to 80° Celcius, which displays that the batteries could have applications in space.
When asked why are there not more companies making this battery tech Nicol said that it is because one needs a very high grade of graphene to make these batteries work.
GMG's batteries are made from a proprietary natural gas method which produces incredibly pure graphene.
Overall this interview is definitely worth checking out if you're interested in graphene or green tech in general: https://youtu.be/_cm3NlQUZlA
