Recently, SiNodeSystems (SNY), a developer of silicon graphene materials for lithium-ion batteries in the United States, and JNC, a Japanese specialty chemical manufacturer, announced that they will jointly establish NanoGraf, a joint venture dedicated to promoting the commercialization of graphene-silicon lithium-ion batteries and advanced materials. The joint venture has invested $ 4.5 million to advance the research and development of new power battery technologies.
According to reports, NanoGraf's battery materials can be customized to achieve capacities between 1000mAh / g and 2500mAh / g, providing higher battery-level energy density and faster charge-discharge efficiency for high-discharge applications. And this is exactly the negative material patent mentioned in the previous SNY public information using the layered structure of composite silicon and graphene. This technology was developed by its team in collaboration with researchers at Northwestern University and Argonne National Laboratories, and patented the technology.
Nanograf has confirmed this on a test production line in Japan. NanoGraf will use the new funds to expand the production scale of its silicon graphene composite anode materials and continue to develop more material platforms. Through the cooperation agreement, NanoGraf will acquire production facilities in Japan, expanded global distribution channels, more than 50 patents, and two research institutions.
The unique combination of a silicon-based alloy and a flexible 3D graphene network is reported to help stabilize the active material during charging and discharging. NanoGraf materials have shown that it can increase battery energy and power density by up to 50% and provide the best cycle life compared to similar products.
About SNY
On November 16, 2017 (Eastern Time), the coatings giant PPG Group announced that it has partnered with SiNodeSystems (SNY) to develop the next-generation silicon graphene composite anode material (lithium anode material). Formally entered the lithium battery industry. It is worth mentioning that 50% of the project's expenditure is funded by the US Department of Energy, and the other half is responsible for several partners, including PPG.
The statement from the PPG Group
This 30-month project will enable partners to quickly develop and demonstrate anode materials that will store more energy than traditional lithium-ion battery materials, enabling electric vehicles to be charged on a single charge or with a lighter battery Drive further. PPG researchers said that we believe that SNY's technology has great potential to benefit the battery market, and we appreciate this opportunity to cooperate. The announcement also mentioned that the project's free graphene will be provided by Canada's Raymor Industries.
About JNC
JNC Co., Ltd. (parent company Chisso Co., Ltd.) is the world's first company to develop ES fiber, and enjoys a high international reputation in the field of sanitary materials. ES fiber is a two-component composite fiber. Hot air non-woven fabric made of 100% ES fiber has been widely used in high-end sanitary napkins, diapers and other sanitary products with its excellent characteristics. evaluation of. In 2000, JNC Corporation and American Fibervisions established a joint venture, ESFibervisions, to sell ES fiber products worldwide.
