Grafoid is a private company based in Canada that aims to produce graphene on a commercial scale using their proprietary extraction process. The company is also active in high-growth, scalable graphene projects, patents and material applications. In May 2013, the company (together with Graphite Zero, of which it holds a majority stake) launched the MesoGraf brand of affordable high-quality graphene materials under the MesoGraf brand.
Grafoid is collaborating on Graphene research with Focus Graphite (which used to own 40% of Grafoid, although it is only a minor shareholder now) and the two companies are still linked by a 10-year offtake agreement. Grafoid is also co-developing graphene-based polymer and non-polymer applications with Rutgets University.
In July 2013 the company raised $3.5 million from private investors. In February 2015, Grafoid received a $8.1 million CAD ($6.46 USD) grant from the Canadian government. In March 2016 China's Xiamen signed a strategic agreement with Grafoid and agreed to buy up to 20% of the company.
Grafoid did not provide any updates since 2021, it is not clear whether the company is still in business.

Vaulta enters MOU with Braille, Grafoid and Focus Graphite to explore applications for its graphene-enhanced battery casings
Australian battery casing company, Vaulta, has announced the signing of a memorandum of understanding with Braille, Grafoid and Focus Graphite.
Vaulta signed the MOU to pair its innovative graphene-based cell casing technology with three Canadian companies focused on battery energy solutions and the development of creative applications for graphene. Vaulta will work with Braille Energy Systems Inc. (BESI), Focus Graphite Inc. and Grafoid Inc. to conduct market analysis to identify new sectors of interest and co-developed projects.
Grafoid and Stria terminate their plan to merge
In October 2020 we reported that Grafoid and Stria Lithium have announced a reverse takeover which will result in Grafoid becoming a wholly-owned subsidiary of Stria Lithium.
Grafoid now announced that the deal is terminated "Due to matters beyond the reasonable control of Stria and Grafoid".
Stria Lithium takes over Grafoid in a reverse takeover
Grafoid and Stria Lithium have announced a reverse takeover which will result in Grafoid becoming a wholly-owned subsidiary of Stria Lithium (it is not clear but the agreement could result in the combination of the two enterprises).
Grafoid says that the new enterprise will get a new name, which will be agreed upon soon. The new company's board of directors will consist of 10 directors, out of which 6 will be nominated by Grafoid (which means that Grafoid will actually control the new company).
Grafoid launches a new company to focus on graphene 3D Printing
Canadian graphene developer Grafoid announced that it launched a new company, called Grafprint3D, to develop and produce 3D printing materials based on Grafoid's MesoGraf graphene - although Grafprint3D's current materials are actually graphene inks for screen printing and inkjet printing and not 3D printed ones.
Grafoid says that initially the new company will focus on wearable device fabrication with biocompatible polymers, biomaterial substrates for cell therapy engineering research, and rapid product prototyping with printable advanced nanomaterials.
Grafoid and Stria Lithium co-develop graphene-based membranes that improve lithium extraction
Grafoid and Stria Lithium have announced the successful co-development of an innovative graphene-based filtration membrane to separate Magnesium and Calcium from salars. Developed in concert with Grafoid Inc. a related company sharing common directors and an active partner in the 2GL Green Energy Technology Strategic Alliance this filtration membrane functions as a precursor that promotes efficiencies within the conventional process of recovering Lithium from Salts.
The Companies explain that the key method of recovering commercial lithium has remained the same for over half a century: by evaporating brines collected from salars and salt lakes in evaporation ponds. However, this method is time consuming and can take a year or more - leading to large amounts of salt waste. In addition, Magnesium and Calcium are also present and form impurities that must be refined out in the process. With the demand for lithium outpacing the recovery rate of lithium from brine faster and more efficient methods of recovery will be critical to supply the growing demand.
Grafoid and Liquinex to collaborate on water purification solutions using MESOGRAF graphene-based filtration technology
Grafoid has announced a strategic partnership with Liquinex, a company specializing in waste water engineering needs, to provide commercial scale water treatment solutions using Grafoid’s MESOGRAF graphene-based filtration technology.
The graphene-based filtration products are said to be readily scalable to meet the rising commercial demands making them ideal for industrial level, niche applications such as the concentration of beverages, treatment of crude oil/water mixtures, biofuel and industrial wastewater treatments where reverse osmosis (RO) is not suitable due to the fouling tendencies when concentrated liquids are purged through RO cartridges.
Grafoid unveils GPURE graphene membrane for Li-ion batteries
Grafoid, the Canadian graphene R&D, investment and technology company, announced the development of its GPURE Graphene Polymer nano-porous membrane intended for next generation Li-Ion battery applications.
The GPURE graphene polymer membrane (GPM) was developed as a chemically inert, freestanding membrane using graphene composites to test ion selectivity using both monovalent and divalent ions. Ion selectivity is a key requirement for a semi permeable membrane in a Li-ion battery structure. By protecting the sensitive electrode materials from unwanted chemical species GPURE GPM diffuses only energy harvesting monovalent ions such as Li+, Na+ etc.
Grafoid develops GPURE Graphene-based membrane technologies for industrial markets
Grafoid has announced the development of the GPURE Membrane Platform, consisting initially of six next generation GPURE Graphene-Polymer membrane technologies intended for industrial markets.
GPURE Graphene-Polymer membranes include:
- GPURE (A) - A high performing, free-standing membrane developed for water desalination applications
- GPURE (B) - A stable, large area membrane developed for wastewater filtration suitable for very high temperature operating applications
- GPURE (C) - A large area free-standing membrane developed for water filtration pre-treatment and may be suitable for use in gas separation applications and may be used as a lightweight component for automotive and sports equipment applications
- GPURE (D) - A large area membrane that may be used for gas separation and sensing applications
- GPURE (E) - A large area membrane intended for use in gas separation applications
- GPURE (F) - May be applied as a graphene varnish for wood surfaces to protect against moisture, UV light and high temperatures
Grafoid unveils a cost-effective graphene coating called GrafeneX
Grafoid, a leading graphene R&D and investment company, announced its entry into the global industrial coatings market with the introduction of its patent pending GrafeneX graphene coatings technology. Grafoid describes the GrafeneX technologies as a cost-effective way of laying down graphene coatings on large surface areas.
GrafeneX is a novel technology that creates a platform for the deposition of graphene and chemically functionalized graphene coatings. This process provides Grafoid with the capability to apply its diverse graphene-based coatings to many different types of material substrates with controllable levels of surface coverage, thickness etc. to meet precise end user requirements.
Grafoid enters agreement to sell its share in Braille Batteries
Mincom Capital has announced it has entered into a non-binding letter of intent with Grafoid to acquire Grafoid's 75% interest in Braille Holdings which owns Braille Battery. The proposed purchase price is $2 million USD, of which $1 million USD will be paid in cash and $1 million USD will be paid in shares issued to Grafoid from the treasury of Mincom. To fund this acquisition, Mincom plans to raise around $3 million USD.
Grafoid stated that "We see future market opportunities for high performing next generation batteries in the bus and truck manufacturing sectors and we see trends emerging in marine, aviation and medical equipment and other industrial sectors that might benefit from graphene-based energy solutions".
