Saint Jean Carbon has reported the results of the first phase of its graphene battery project, announced in January, 2017. According to SJC, while primary at this point, the graphene battery has outperformed the graphite battery, as shown by a greater discharge capacity of about 30%. Both batteries were manufactured with the same material, battery A graphite anode and B graphene anode.

The company supplied performance results, among which are the graphite anode’s theoretical capacity of 372 mAh/g and the theoretical capacity of the graphene anode of 700 mAh/g. Beyond 100 cycles the discharge capacity for the graphite was 200 to 220 mAh/g and for the graphene 310 to 330 mAh/g. The testing processes included charging to 3V at 500 mA/g and discharging to 0.05V at 100 mA/g. SJC said that neither the graphene nor graphite was enhanced so the variations in the results have to be additionally tested.

Saint Jean Carbon recently announced that it has started the design and build of a graphene based lithium-ion battery. SJC stated that based on the Company’s graphene production capabilities, the material being produced is 99.999999%gC and a single layer of graphite measuring one atom in thickness will be used to create the anode.

This announcement follows two years of research, and the Company feels that due to the fact that no harsh chemicals or heat has been used to produce the graphene, the high order of carbon is kept in perfect condition, creating the possibility of extremely high performance for lithium-ion battery applications.

Saint Jean Carbon, a carbon science company engaged in the design and development of carbon materials and their applications, recently received (along with Western University) a grant from the The Natural Sciences and Engineering Research Council of Canada (NSERC) towards the development of graphene-based systems with special magnetic properties.

The $100,000 grant will be used to cover the cost of the lab work, testing, material creation and all research associated costs. The company stated that it aims to use the funds to get beyond the lab and into working prototypes, scaled models and future commercial production. In addition, SJC hopes that "the results will play a big role in the medical field as well in energy storage for electric cars and green energy creation".

Saint Jean Carbon, a carbon science company engaged in the exploration of natural graphite properties and related carbon products, has announced the development of hybrid graphene sheets with superconductivity. The work is the ongoing development of a number of different areas of research between Saint Jean and University of Western Ontario.

The hybrid graphene nanosheets were created by depositing yttrium barium copper oxide (YBCO) superconductor particles and were developed by using the matrix-assisted pulsed laser evaporation (MAPLE) method. With increasing irradiation time, the amount of YBCO nanoparticles deposited on graphene is increased. In addition, the microstructures and elemental composition of YBCO nanoparticle deposited on graphene sheet by the MAPLE process were studied in terms of particle size and shape as a function of the deposition time/irradiation time. It is noted that the shape and size of the YBCO nanoparticles are more uniform with increasing the deposition time. When it increases to 2 hours, the average diameter of the spherical YBCO nanoparticles deposited on graphene sheets is around 50 ± 10 nm. This study demonstrates that MAPLE is a suitable process for depositing inorganic superconductor nanoparticles on graphene sheets without additional chemical agents.

Saint Jean Carbon, a carbon science company engaged in the exploration of natural graphite properties and related carbon products, has announced that it has produced two samples of single layer graphene (1) dispersion 20 mL, 0.1%, with pure 100 mL water and (2) a 50 mg of powder.

The material is said to have been produced without any chemicals or any mechanical systems that would harm the high order of carbon structure and wettability. The material has been sent to National Research Council and will be used to help set the national standard for graphene production and quality.

Saint Jean Carbon, a carbon science company engaged in the exploration of natural graphite properties and related carbon products, has teamed up with the University of Western Ontario to create graphene that has a magnetic field (Magnetoresistance).

One of the involved researchers explained that: "Magnetoresistance (MR) refers to the significant change of electrical resistance of materials under a magnetic field. Magnetoresistance effects have been applied in magnetic sensors, spintronic devices and data storage. Magnetic sensors are extremely useful for today's industry for measurement and control purposes... This happens by detecting changes in electrical resistance brought on by the presence of a magnetic field. This is also known as magnetoresistance (MR). The market size of the magnetic sensor is increasing with annual growth rate at 10% because of new nanomaterials..."

Saint Jean Carbon announced that it has been invited by the National Research Council (NRC) of Canada to take part in a special interest group that will develop and propose standards for graphene made by exfoliation methods from natural graphite. The project will be broken into a number of phases; the first phase will take approximately one year to complete.

The NRC sees an excellent opportunity for graphene producers to work together in collaboration with the NRC to determine the optimal techniques to properly characterize graphene and develop standardized methods for use in confidently comparing graphene materials, thereby strengthening the graphite industry as a whole.

Saint Jean Carbon, a publicly traded carbon science company, announced that it, along with their industry partners, will complete a prototype of a graphene-enhanced diamagnetic wire that will conduct energy at room temperature with superconducting level resistance. The process to build the wire is planned to take a few months, and the model will first be prototyped at 36 inches in length with a goal to measure the energy resistance under varying loads. This should, for example, give a better understanding on how a superconducting wire can greatly enhance the electricity transfer from an electric motor to a battery.

The design is based on relatively simple principles: the outer housing (casing) is a non-conductive rubber compound and the inner sleeve is a resin binder with a high concentration of diamagnetic graphene. The center core is a magnetic graphene wire and the diamagnetic force holds the center core in place while the energy passes along the path of the neutralized middle core.

Saint Jean Carbon, a company engaged in the development of natural graphite properties and related carbon products, has announced that it has received another grant from Natural Sciences and Engineering Research Council of Canada (NSERC), In addition to the grant received in October 2015.

The funds will be used to further the material knowledge of the Saint Jean Carbon ferromagnetic graphene. This research is the next step in the development of understanding where the material can be used in future applications, and provides a further understanding of the unique properties contained in the ferromagnetic graphene. The company states that the funds provide it with a very special opportunity to work with top universities like Western University, and their bioengineering team.

Saint Jean Carbon, a publicly traded junior mining exploration company, has announced that it has secured a research grant from the Natural Sciences and Engineering Research Counsel of Canada (NSERC).

The grant covers the cost from the research and development work conducted at the University of Waterloo Applied Carbon Nanotechnologies Laboratory, where the company has been working on a number of projects, such as working towards creating superconducting room temperature graphene, using the patented sonicating method to better understand how to produce mass quantities of graphene and working toward building greater efficiencies in lithium battery grade materials.
