    摘要: A thermal battery includes a first conductive layer containing an anode material separated from a second conductive layer containing a cathode material by a separator layer containing a separator material; and a flexible pyrotechnic heat source, wherein the first conductive layer, the separator layer, and the second conductive layer are rolled together to form the spiral wound configuration. A method of manufacturing a thermal spiral wound battery includes preparing three slurries, each containing one of an anode material, a cathode material, and a separator material, depositing each of the materials from the slurries onto conductive substrates to form three layers, stacking the layers, and winding the layers together into a spiral wound configuration.

    摘要: At least a portion of the enclosure of a thermal battery is formed of a ceramic material that is non-porous and electrically-non-conductive. The thermal battery includes at least one cell, a squib that when activated causes the at least one cell to become active, and an enclosure that surrounds the at least one cell and the squib. Squib terminals and battery terminals extend through the enclosure and are electrically connected to the squib and to the at least one cell, respectively. At least the portion of the enclosure through which the squib and battery terminals extend is formed of the ceramic material. The enclosure includes a container and a header. At least the header is made from the ceramic material, and preferably both the container and the header are made from the ceramic material.

    摘要: A system and method use an open-circuit voltage (OCV) method of calculating a state-of-health (SOH) of a chemical battery. The OCV system and method includes charging the battery to a maximum charge potential, determining an open-circuit voltage (OCV) of the battery after waiting a predetermined period of time after completion of the charging, and determining the SOH of the battery based on the determined OCV of the battery. Another system and method use a time-to-charge (TTC) method of calculating a state-of-health (SOH) of a chemical battery. The TTC system and method includes monitoring and storing a charge time of the battery in a memory and scaling the stored charge time to form an SOH indication.
