  • Patent number: 11374276
    Abstract: A Li-ion battery is provided in combination with fluorinated material positioned effective to abate combustion by said battery, the fluorinated material being normally non-gaseous and non-liquid and being itself effective to provide the combustion abatement by said battery, such fluorinated material being is such forms as the material of construction of the battery case containing the battery, film wrapped around said battery, and/or semi-solid material at least proximate to the battery, such as by forming a coating on said battery or said film on said battery.
    Type: Grant
    Filed: September 27, 2019
    Date of Patent: June 28, 2022
    Assignee: THE CHEMOURS COMPANY FC, LLC

  • Publication number: 20140060859
    Abstract: Abatement of combustion by Li-ion battery is achieved by positioning a mixture comprising a thermally destabilizable solid fluoropolymer and a fluorinated composition with respect to the battery, the positioning being effective to provide the abatement of combustion of the battery, the mixture preferably being a semi-solid and having the proximity to the battery to provide the combustion abatement effect, preferably as a coating on at least a portion of the battery.
