Verfahren und Vorrichtung zur Behandlung einer Alkalimetall enthaltenden Batterie

摘要

A safe and controllable method of treating a secondary battery (15) having at least one component containing alkali metal, comprises the steps of opening the battery casing, and introducing a gas containing at least one of water vapour and alcohol vapour into a closed chamber (1) containing the battery thereby to form alkali metal hydroxide. To control hydrogen concentration, the rate of introduction of water and alcohol vapour may be varied. Apparatus for carrying out this method is also described.
