A C$6 million equity financing in February 2025 fueled capacity expansion and commercialization initiatives.

Graphene Manufacturing Group (TSXV:GMG, OTCQX:GMGMF) valued at C$101.09 million focuses on energy-saving solutions and storage technologies. The company is advancing graphene aluminum-ion battery development in collaboration with Rio Tinto and the University of Queensland. A new Gen 2.0 manufacturing plant with an estimated AU$2.3 million capital cost is expected to become operational by June 2026, initially producing at 1 metric ton annually with planned escalation to 10 metric tons per year.

Specialized Markets and Niche Applications

Directa Plus (LSE:DCTA) with a GBP 11.24 million market cap produces graphene nanoplatelets for textiles and composites under its proprietary G+ Graphene Plus brand. The company’s subsidiary Setcar secured multiple environmental service contracts in 2025, including agreements with Midia International (€1.5 million), Ford Otosan (€1.1 million renewal), and OMV Petrom (€1.59 million) utilizing its Grafysorber oil recovery technology.

First Graphene (ASX:FGR, OTCQB:FGPHF) valued at AU$39.14 million converts ultra-high-grade graphite into competitively priced bulk graphene. The company’s Kainos technology secured patents from Australian and South Korean governments in 2025. Recent developments include an exclusive supply agreement with Indonesian safety boots manufacturer Alasmas Berkat Utama for approximately 2.5 metric tons of PureGRAPH masterbatch over two years, and a collaborative research initiative with Imperial College London and University College London on graphene-enhanced 3D metal printing for aerospace and motorsports applications.

CVD Equipment (NASDAQ:CVV) with a market cap of US$18.82 million manufactures chemical vapor deposition systems applicable to graphene and nanomaterial production. The company reported 2024 revenues of US$26.9 million, up 11.5 percent year-over-year, driven by aerospace contracts and semiconductor work. First-half 2025 revenue reached US$13.4 million, up 19.2 percent, with Q1 alone demonstrating 69 percent year-over-year growth to US$8.3 million.

Haydale Graphene Industries (LSE:HAYD) holds a market cap of GBP 23.78 million and collaborates with the University of Manchester’s Graphene Engineering Innovation Centre on conductive ink heating technologies. In 2025, the company secured commercial contracts for graphene heating systems from Affordable Warmth Solutions and achieved CE certification for its JustHeat graphene-based heating product, meeting European safety and environmental standards.

Understanding Graphene Fundamentals

What Defines Graphene?

Graphene comprises a single atomic layer of carbon atoms arranged in a hexagonal lattice structure. First successfully isolated in 2004 at England’s University of Manchester, the material exhibits extraordinary properties: it is approximately 200 times stronger than steel while being thinner than a sheet of paper. Applications span batteries, sensors, solar cells, electronics, medical devices, and sporting equipment.

Key Properties Driving Industrial Adoption

Graphene’s remarkable characteristics include superior thermal and electrical conductivity, exceptional elasticity and flexibility, significant hardness and durability, transparency, and the capacity to generate electricity through solar exposure. These properties position graphene as a versatile solution for next-generation technological applications.

Graphene Versus Graphite: Essential Distinctions

Both graphene and graphite represent different crystalline forms of carbon. The fundamental distinction lies in structure: graphene is essentially a single layer extracted from graphite, which consists of multiple stacked graphene sheets. This structural difference results in dramatically different physical and chemical properties between the two materials.

Beyond Public Markets

The graphene investment landscape extends beyond publicly traded entities. Private companies including ACS Material, Advanced Graphene Products, Graphene Platform, Graphenea, Grafoid, and Universal Matter are also advancing graphene technology development and commercialization.
