Abstract
An assembly for preventing a fire resulting from the outgassing of a lithium battery in an electronic door lock includes a lithium battery, a circuit board, and a thermal insulation. The lithium battery and circuit board are housed within the electronic door lock. The thermal insulation is arranged between a door interfacing side of the electronic door lock and either or both of the circuit board and lithium battery. Another thermal management technique for preventing fire resulting from the outgassing of a lithium battery in an electronic door lock is achieved by using a battery cover that is selectively movable away from the circuit board or ignition source in response to temperature rise to ensure the lithium battery does not reach a critical temperature that may cause outgassing in close proximity to the ignition source.
