Graphene Manufacturing Group (TSXV: GMG) announced on September 14, 2026, that its 1 Ah G®CELLS have completed 489 charge-discharge cycles with no reduction in performance, each cycle lasting just six minutes. The tests were conducted by the Battery Innovation Center (BIC) in Indiana, using cells developed, manufactured, and supplied entirely by GMG.
The comparison with conventional batteries is stark. A Lithium Titanate Oxide (LTO) cell — a technology well known for its resilience under fast-cycling conditions — lost approximately 14% of its original capacity after just 64 cycles under the same test parameters. The G®CELLS, by contrast, operated for more than seven times as many cycles without showing any of the degradation recorded in the reference cell. The numbers speak for themselves. Six-minute recharging is a particularly compelling specification for industrial applications and stationary energy storage systems, sectors where cycle speed directly impacts overall operational efficiency.
These test results come at a broader growth moment for GMG. The company has launched an Asia Pacific Sales Team with business development operations in India, South Korea, Japan, and Singapore — alongside Australia, which is already part of the company’s operational footprint. The move is designed to open commercial channels in the region’s largest industrial and technology markets, where demand for high-performance energy storage solutions is expanding rapidly. India and Japan, in particular, are making substantial investments in energy infrastructure and electric mobility, making the timing of this geographic expansion well-aligned with current market dynamics.
GMG’s portfolio extends well beyond G®CELLS. The company’s product platform includes the Gen 2.0 Graphene Manufacturing Plant, the thermal management material THERMAL-XR®, the G® LUBRICANT, the G FLUID™ cooling fluid for AI data centers, and a collaboration with Alstom in the railway sector. In addition, the company is developing Graphene-Aluminium Ion Battery technology as a separate line of innovation distinct from G®CELLS. This portfolio diversification reduces reliance on any single product and broadens the range of potential commercial applications across target markets.
If ongoing tests continue to confirm G®CELLS stability beyond the 489 cycles already documented, GMG will have sufficient third-party-verified data to engage in concrete commercial discussions with manufacturers and system integrators across Asia. The combination of independently validated laboratory results and an active regional sales network is the baseline requirement for moving from the experimental phase to signed contracts. 2026 could well prove to be the year this technology transitions from a promising concept to a market-ready product.
