  • Compositions with increased electrical conductivity
    Patent number: 11807750
    Abstract: Thermoset bulk molding compounds (BMC) useful for making electrically conductive components such as bipolar plates for fuel cells are described. The thermoset bulk molding compounds incorporate graphene nanoplatelets to increase the through-plane electrical conductivity by at least 20% compared to BMCs without the graphene nanoplatelets. Additionally, these compositions have low shrinkage, low density for lightweight parts, and are easily processed. The compositions can be used to prepare a variety of electrically conductive components, including bipolar plates for fuel cells and chemical storage batteries that operate at temperatures of less than 100° C.
    Type: Grant
    Filed: July 6, 2021
    Date of Patent: November 7, 2023
    Assignee: LyondellBasell Advanced Polymers Inc.
