XG Sciences is a private company based in Michigan, US, that develops and producer graphene flakes using technology developed at Michigan State University.
XG Sciences uses its xGnP (graphene flakes) materials to also develop graphene applications. In August 2013, XGS launched a new graphene-based anode material for Li-Ion batteries. In August 2012 the company started production in their new 80 ton facility in Lansing, MI.
In 2014 Samsung Ventures placed a strategic investment in XGS as the two companies aim to co-develop graphene-enhanced batteries. In July 2013 we posted an interview with the company's co-founder and CEO.
Towards the end of 2018 XGS announced its production capacity has been expanded to 180 tons per year, with plans for further expansion to 400 tons/year.
The latest XG Sciences graphene news:
XG Sciences has announced the completion of the first phase of expansion in its newest 64,000 square-foot facility. The expansion has added 90 metric tons of graphene nanoplatelet production capacity, bringing the total capacity of the facility up to approximately 180 metric tons and enabling the formulation of up to 18 million kilograms of advanced materials per year. Phase two of the expansion is expected to be complete by year-end and will result in up to 400 metric tons of total graphene nanoplatelet output capacity at the facility.
XG's total graphene nanoplatelet output capacity across both of its manufacturing facilities currently exceeds 200 metric tons per year and will more than double over the next three months, reaching up to an approximate 450 metric tons by year-end. The expansions support XG’s mission to continue commercializing the use of graphene in customer products across diverse industries.
XG Sciences, a US-based developer and producer of graphene flakes, has announced its plan to invest millions in expanding its Lansing-area facilities. The company will start operating out of new 64,000 square-foot facility in Vevay Township in March.
The company was formed in 2006 based on work out of Michigan State University. The company's technology can be used in automotive batteries and as wire coatings in electronics to prevent microchips from overheating. Some of the material has been used in Samsung phones as a thermally conductive adhesive, said current CEO Philip Rose. Rose also said the expansion marks the first phase in a move toward larger scale commercialization for the company.
XG Sciences, a supplier of graphene nanoplatelets and value-added products containing graphene nanoplatelets, recently announced that it has closed an agreement with The Dow Chemical Company for up to a $10 million senior credit facility, which may be drawn down in tranches by XGS at its discretion through December 2019.
The company received $2 million under this facility at close and may draw another $3 million at its discretion at any time prior to the first anniversary of the agreement. After the first anniversary of the closing, the company may access the remaining $5 million, provided it has raised at least $10 million of additional equity capital. XG Sciences and Dow agreed to hold commercial discussions including the potential out-license of certain of Dow’s manufacturing IP related to graphene nanoplatelets to XGS.
I recently had an interesting talk with XG Sciences' Sr. Director of Business Development, Dr. Percy Chinoy. Percy updated on XGS' technology and business. Among several other applications of graphene, XGS has been collaborating with battery developers and their supply chain partners for a few years.
XGS is involved in three battery-related applications: silicon-graphene electrodes, and graphene additives in Li-Ion battery and Lead-acid battery electrodes. As a supplier, XGS has to work with the product schedules of other companies - but XGS is positive that we will see these products being launched in 2017.
XG Sciences has received a DOE Round 2 small business award for $150,000, which it will use to support its efforts to develop low-cost manufacturing of a silicon-graphene composite anode. According to the company, one goal for the new anode type is to reduce the formation of the solid electrolyte interface (SEI).
The SEI layer is a film composed of electrolyte reduction products that start forming on the surface of the anode during the initial battery charge. It functions as an ionic conductor that enables lithium to migrate through the film during charging and discharging – allowing the battery to operate in an efficient and reversible manner. Under typical operating conditions, it also serves as an electronic insulator that prevents further electrolyte reduction on the anode. However, as the silicon in next-generation anodes expands and contracts, it essentially cracks apart that layer and then makes more. Over time it ends up with a very thick resistive film on the anode, which causes it to lose both capacity and power.
