Graphene Manufacturing Group Ltd. reports developments in graphene-enabled energy-saving and energy-storage products. The Australian clean-technology company develops, makes and sells products based on graphene produced through its proprietary process that decomposes natural gas into carbon as graphene, hydrogen and residual hydrocarbon gases.
Recurring news covers THERMAL-XR graphene coating applications for HVAC-R and other industrial uses, G® LUBRICANT patent activity, verified graphene-producer and ISO 9001 quality updates, sales expansion, production growth plans, and progress on graphene aluminium-ion battery technology developed with the University of Queensland. Updates also address graphene additive slurry for lithium-ion batteries and regulatory authorizations for commercial product sales.
Graphene Manufacturing Group (GMGMF) has begun supplying G®CELLS battery pouch cells to potential customers for early-stage testing and evaluation. The first samples have been dispatched, with GMG expecting to supply over 100 cells before the end of 2026, including to defence and heavy mobile equipment sectors. Development is supported by a joint development agreement with Rio Tinto and collaboration with Battery Innovation Center of Indiana.
The technology remains at battery technology readiness Level 4, meaning laboratory validation; samples are not for commercial products. Previously announced laboratory results included no performance reduction after 1,000 cycles, energy density of 58 Wh/kg and 94% energy efficiency. Customer results may differ with testing conditions. GMG plans to collect feedback while improving energy density, fast-charge cycle life and cell sizes; no definitive timeline is available for reaching Levels 7 or 8.
Graphene Manufacturing Group (GMGMF) has appointed nine-time Motocross World Champion Antonio Cairoli as brand ambassador to support its motorcycle lubricant development. Cairoli, also a Ducati test rider, will initially evaluate G® LUBRICANT, a graphene engine oil additive, in his own compatible vehicles away from the racetrack. GMG expects his feedback to inform development for off-road applications, with racing a future aim. Further testing and validation are needed for both uses.
Under a separate program, Massimo Fogliaro's A-Team will begin testing the additive under motocross competition conditions. GMG will exhibit at EICMA 2026 on November 3–8 at Fiera Milano Rho in Milan, in Hall 9-11, Stand Q58. Cairoli will attend for an autograph session and introduce the collaboration; A-Team will present its new Honda prototype.
Graphene Manufacturing Group (GMGMF) reported a 48% increase in graphene battery energy density in testing involving six-minute charging.
Energy density reached 58 Wh/kg, versus the previously reported 39 Wh/kg, at a 10C charge rate. Battery Innovation Center of Indiana built and tested cells using GMG-supplied materials. As of October 7, 2026, cells charged and discharged in six minutes at 7C completed 1,000 cycles without performance reduction, doubling the previously reported cycle life. A separate cell tested at 10C lost 10% of capacity after 393 cycles; the tested lithium titanate oxide battery fell to 80% of original capacity within 82 cycles. Energy efficiency was 94%, versus 64% for that benchmark.
GMG plans to improve energy density and 10C cycle life and scale to larger cells. Development continues under a joint agreement with Rio Tinto.
Graphene Manufacturing Group (GMGMF) raised C$1,366,396.10 in gross proceeds through its at-the-market share-sale program during the quarter ended September 30, 2026.
It issued 575,630 ordinary shares at an average C$2.374 per share. Commissions of C$40,848.53 left net proceeds of C$1,325,547.57. The program, launched July 11, 2025, permits sales of up to C$20,000,000 of ordinary shares.
Graphene Manufacturing Group (GMGMF) closed a non-brokered private placement with a private investor for approximately US$10 million in gross proceeds.
The investor subscribed for 6,465,336 ordinary shares at CA$2.15 per share. The placement has received conditional approval from the TSX Venture Exchange. No finder's fees or commissions were paid.
The company intends to use the net proceeds to expand graphene, liquid graphene and battery cell production capacity, commercialize liquid graphene products, and fund working capital and general corporate purposes.
Graphene Manufacturing Group (GMGMF) entered a subscription agreement for a private placement of 6,465,336 ordinary shares at CA$2.15 per share, for total gross proceeds of approximately US$10 million, subject to TSX Venture Exchange approval.
The company plans to use net proceeds to scale graphene and liquid graphene production capacity, expand battery cell production capacity, commercialise liquid graphene products, and for working capital and general corporate purposes. Closing is expected on or about September 23, 2026, or on another agreed date, conditional on all required regulatory and Exchange approvals. No finder’s fees or commissions are payable on the financing. The securities will be issued under U.S. Securities Act Section 4(a)(2) and Regulation D exemptions, will not be registered under the Securities Act, and will be subject to 12‑month on‑sale restrictions in Australia.
Graphene Manufacturing Group (GMGMF) marked the official opening of its Gen 2.0 graphene manufacturing plant on 19 August 2026, at its Boundary Facility and headquarters in Brisbane, officiated by Queensland Assistant Minister for Regional Development, Resources and Critical Minerals, Bryson Head.
Mr. Head described the plant as an important step for Queensland’s critical minerals and advanced manufacturing ambitions, highlighting local innovation, skilled jobs and sovereign capability. GMG expects that, once fully complete and optimised, the Gen 2.0 Plant will be largely self-powered through standalone renewable energy generation, an energy storage system and hydrogen-enriched natural gas from tail gas power. The Tickford Racing Team, a GMG partner, also participated in the opening event.
Graphene Manufacturing Group (GMGMF) will host a live fireside chat on September 17, 2026 to discuss recent G(R)CELLS battery milestones and the launch of its G(R)FLUID cooling additive.
Topics include 1 Ah G(R)CELLS testing that reached 489 fast charge–discharge cycles at a 10C rate with no measurable performance reduction, compared with a benchmark Lithium Titanate Oxide cell that fell to 86% capacity after 64 cycles. The event will also cover G(R)FLUID test results showing about 20% higher heat transfer and up to 87% anti-microbial performance, plus updates on an Asia Pacific sales team expansion and a Blackwoods distribution agreement.
Graphene Manufacturing Group (GMGMF) reported new long-life cycling data for its fast-charging 1 Ah G®CELLS under a joint development program with Rio Tinto, tested by the Battery Innovation Center (BIC) in Indiana.
BIC-built cells using GMG materials showed no measurable performance reduction after 489 cycles at a demanding 10C charge and 10C discharge, with each full cycle completed in six minutes as of 4 September 2026. Under the same profile, a benchmark Lithium Titanate Oxide (LTO) cell degraded to about 86% of original capacity within 64 cycles, near the typical 80% end-of-life threshold, meaning G®CELLS lasted over seven times longer in this test.
At 10C/10C, G®CELLS delivered 39 Wh/kg energy density, a 4°C rise above 25°C ambient and about 0.005 Ohm resistance, versus LTO’s 37 Wh/kg, 19°C rise and up to 0.030 Ohm. The company stated that current energy density is lower than previously reported and believes further optimisation could lift it back toward about 50 Wh/kg at a 10C charge rate.
Graphene Manufacturing Group (GMGMF) has launched its dedicated Asia Pacific Sales Team, which has been conducting business development across the region since early 2026.
The team is initially based in India, South Korea, Japan, Singapore and Australia, extending GMG's go-to-market footprint beyond its existing operations. Management describes the move as an important step in the company’s global commercialisation strategy for graphene-enhanced thermal, lubricant and energy storage solutions. The regional build-out is presented as complementing recent production milestones, including the start-up of GMG’s Gen 2.0 graphene production plant, and is intended to help convert growing demand into commercial outcomes across key industrial economies.
