- Description
- Opportunity: Lawrence Livermore National Laboratory (LLNL), operated by the Lawrence Livermore National Security (LLNS), LLC under contract no. DE-AC52-07NA27344 (Contract 44) with the U.S. Department of Energy (DOE), is offering the opportunity to enter into a collaboration to further develop and commercialize its skin-layered microporous separators for lithium-ion batteries. Background: Secondary Li-ion batteries are rechargeable electrochemical energy storage devices typically used in high-powered applications, including portable electronics, vehicles, and grid energy storage.� These batteries consist of a porous separator sandwiched between a positive and negative electrode and wetted with electrolyte that is ionically conductive but electrically insulating.� The separator ideally allows just the Li ions to shuttle back and forth during cycling.� Currently, conventional separators may not be as selective and allow other ions such as polysulfide anions to shuttle through the pores, which degrades battery (Li-sulfur) performance.� Additionally, for high-powered applications, batteries are afflicted with Li dendrite growth � branch-like metal projections that form on one of the electrodes, which can penetrate through the separator and electrically connect the two electrodes.� This bridging causes the short-circuiting of the battery.� For high performance applications, there is a need to develop a separator with a porous structure that can allow for fast Li ion transport without other ions to pass through and can prevent Li dendrites from piercing through.� Description: LLNL�s novel approach is to use separators based on a bilayer structure that consists of a self-formed skin layer on a microporous membrane.� The highly porous membrane is made of 1,6-hexanediol diacrylate (HDDA), which provides high Li ion conductivity.� The skin layer is relatively dense that allows for easy Li-ion transport but can effectively block undesired constituents such as polysulfide anions and Li metal dendrites from passing through the layer.��� This bilayer structure is fabricated on a stage from resin that is exposed to UV light through a transparent membrane such as fluorinated ethylene propylene (FEP).� The resin is composed of one or more of the following: UV curable acrylate monomers, solvents, and porogens.� The formed separators can then be used with conventional liquid electrolytes, replacing conventional separators for lithium-ion batteries. Advantages/Benefits:� Value Proposition:� Improved performance of Li-ion batteries for high-power applications High Li-ion conductivity Low Li dendrite penetration Low polysulfide anion transport Potential Applications:� Li-ion Batteries Li-sulfur Batteries Carbon dioxide separation Hemodialysis Fuel Cells Development Status:� Current stage of technology development:� TRL 3 (Analytical and experimental critical function and/or characteristic proof of concept) LLNL has filed for patent protection on this invention. LLNL is seeking industry partners with a demonstrated ability to bring such inventions to the market. Moving critical technology beyond the Laboratory to the commercial world helps our licensees gain a competitive edge in the marketplace. All licensing activities are conducted under policies relating to the strict nondisclosure of company proprietary information.� Please visit the IPO website at https://ipo.llnl.gov/resources for more information on working with LLNL and the industrial partnering and technology transfer process. Note:� THIS IS NOT A PROCUREMENT.� Companies interested in commercializing LLNL's skin-layered microporous separators for Li-ion batteries should provide an electronic OR written statement of interest, which includes the following: Company Name and address. The name, address, and telephone number of a point of contact. A description of corporate expertise and/or facilities relevant to commercializing this technology. Please provide a complete electronic OR written statement to ensure consideration of your interest in LLNL's skin-layered microporous separators for Li-ion batteries. The subject heading in an email response should include the Notice ID and/or the title of LLNL�s Technology/Business Opportunity and directed to the Primary and Secondary Point of Contacts listed below. Written responses should be directed to: Lawrence Livermore National Laboratory Innovation and Partnerships Office P.O. Box 808, L-779 Livermore, CA� 94551-0808 Attention:�� IL-13812
