High Capacity Silicon-Carbon Anodes

January 8, 2019




United States

pH Matter, LLC (“the company”) is pleased to announce initiation of a $1 million product development project funded by the U.S. Department of Energy for engineered materials for lithium ion battery anodes.  Lithium ion batteries are being increasingly adopted for automotive power applications; however, the lithium capacity of the negative electrode (anode) limits the amount of energy these batteries can store.  Improvements to the anode would increase the energy density and lower the battery cost.  For electric vehicles, lower battery cost and higher energy density would increase the driving range of vehicles, accelerating their adoption.  pH Matter’s approach to improving the anode is based on an engineered composite of carbon and silicon.  The DOE funding is being used to partner with prospective customers to tailor products for their requirements.  As Mr. Chris Holt, the company’s Vice President of Battery Technology and director of the project, stated, “this funding will allow us to accelerate development of our anode technology, and demonstrate the technology under automotive battery conditions”.  The funding was awarded through the DOE’s Small Business Innovation Research (SBIR) program.  The SBIR program is a highly-competitive program designed to provide innovative U.S.-based small businesses opportunities to develop products for global markets and/or in areas of national security interest.

About the Company

Founded in 2010 and located in Columbus, Ohio, pH Matter, LLC is a leading developer of new materials for electrochemical applications, with particular expertise in synthetic carbon-based materials for fuel cells, batteries, and electrolysis.  In conventional rechargeable batteries, graphite is typically used for lithium storage.  Although graphite is low cost and electrically conductive, conventional graphite stores a limiting amount of lithium, and cannot be charged rapidly.  pH Matter’s materials are optimized for important performance and durability attributes, thus reducing overall cell cost and improving performance.  Prospective customers, investors, and project partners can send requests to for more information about pH Matter’s products and development programs.
