6-Minute Fast Charging Without Wear: Graphene Battery Breakthrough
CEO.CA Sep 17, 2026 6:48
Summary
Independent testing showed GMG's graphene cells held up through nearly 500 six-minute charges with no performance loss, versus fast-charging rivals that degrade quickly.
The CEO credits a non-lithium electrolyte and graphene's heat-spreading ability, claiming ions move roughly a thousand times faster than in a standard lithium cell.
The guest concedes others will eventually be able to replicate the cell, but argues in-house graphene production is the harder barrier.
Samples go out to waiting commercial buyers, with the CEO calling this the last phase before pre-commercial scale-up.
The model is licensing technology into idle plants: the CEO says global battery capacity runs three times demand, leaving two-thirds empty.
Craig Nicol's takeaways
- Top takeaway Nicol argues the near-500 six-minute-charge test result with no performance loss is a step change in battery technology and that it puts GMG into the next level of battery developers, with a commercial product close.
- He attributes the fast-charge durability to a non-lithium electrolyte plus graphene's ability to move and spread heat, which he frames as the core of GMG's business.
- He says the battery is simple in construction, being aluminium foil on both sides and a cathode GMG developed itself, and that GMG makes the materials from mined raw materials through full assembly in-house.
- On replication, he says the cell will be built under a patent and, once granted, licensable, which is why he expects GMG to license the process and supply materials to other cell makers.
- He says GMG is starting to speed up the final pre-commercial phase, sending samples to a handful of large companies that have been patient for years, and expects more announcements to shareholders.
