Our history

Axium Nanofibers is a material science company founded in July 2010. Axium’s patented nanomaterials platform was originally developed by Professor Yong Lak Joo and his team at Cornell University. Professor Joo envisioned that an advanced nanofiber manufacturing process could establish the basis for fabricating a diverse range of highly tunable nanocomposites made from both organic and inorganic materials. Axium initiated sponsored research with Cornell to support Professor Joo’s team to begin development of next generation battery materials that could greatly improve the energy density or energy storage capacity of lithium-ion batteries. It was clear from inception that disrupting the mature market for lithium-ion batteries was not going to be a trivial task. However, the Axium team believed strongly that its core competencies in nanoscale engineering and nanocomposites manufacturing set the foundation for developing far superior battery electrodes and separator materials. The Axium team has since developed an advanced electropraying or E-Spray process that was partially inspired by the work in nanofiber electrospinning. The E-Spray process has proven to further improve the performance and lower the cost of Axium’s core products, such as its silicon/graphene anode and its polymer/ceramic separator.

AXIUM Core Competencies

Axium’s nanomanufacturing processes, protected by over 40 filed and issued patents, enable direct integration of graphene, nanoparticles, and other nanomaterials into each individual fiber or nanoscale droplet with controlled dispersion and tunable material properties. This unprecedented materials capability represents virtually limitless commercial possibilities. Conventional nanofabrication technologies, such as sputtering and chemical vapor deposition, typically produce a few grams per hour of nanoscale composites, resulting in very high manufacturing costs. Moreover, these processes are very challenging to scale. Axium’s processes are simple to scale and can produce hundreds of grams of nanocomposites per minute. The Company’s processes can be configured as roll-to-roll systems for direct deposition onto substrate materials, such as a current collector. Axium operates from an R&D facility that also includes pilot manufacturing, an infrastructure enabling rapid prototyping, testing and scale-up of high performance materials.

Revolutionary Nano-Manufacturing

We have demonstrated the ability to leverage the use of materials like graphene, nanotubes and nanoparticles in a scalable process, which has been the barrier to broadly commercializing nanotechnology.

    Eric DonskyCEO and Co-Founder

    Eric Donsky has over 20 years experience in building cleantech and life science companies as a founder and senior manager.  Eric was the founding CEO of TearLab Corporation, a publicly traded, in-vitro diagnostics company (NASDAQ:TEAR) that has successfully commercialized the world’s first point-of-care, testing platform capable of measuring disease markers in tears for the rapid diagnosis of eye diseases. The Company’s patented TearLab™ system has obtained FDA approval, CLIA Waiver, CE Mark, broad reimbursement in the United States, and is marketed in over 25 countries worldwide. Eric was also the founding Chairman of Singularis, a biotechnology company commercializing a highly lubricating, recombinant protein for a number of therapeutic indications, including Dry Eye Disease, vaginal atrophy and interstitial cystitis. The Company has completed several strategic alliances and has its first product in clinical trials. He was the founding CEO of Applied CarboChemicals, Inc. (“ACC”), an industrial biotechnology company that was an early innovator in the development of processes capable of manufacturing chemicals and plastics from renewable resources. ACC, renamed BioAmber (NYSE:BIOA), has developed the 1st process capable of economically manufacturing succinic acid through fermentation at large scale using a novel genetically-engineered bacterial strain original licensed from the U.S. Department of Energy. Succinic acid serves as a chemical intermediate for the synthesis of a vast range of derivative chemistries that function as detergent additives, monomers, polymers, coatings, solvents, among many other applications. BioAmber is building manufacturing capacity in 3 continents around the world and has $4B of contracted revenues. The Company has formed strategic partnerships with DuPont, Cargill, Lanxess, Mitsubishi and Mitsui. The Company is publicly traded on the NYSE. Mr. Donsky graduated from Boston University with a B.S. in Business Administration.
