A Li-Ion monitor (10) includes a combustible vapor sensor (14) positioned in air flow communication with the exterior (18) of a hermetically sealed Li-Ion battery cell (12) to detect combustible vapor (22) escaping therefrom. Detection of the vapor indicates that an overheat or fire situation may be impending. Where the Li-Ion battery cell (12) is immersed in liquid (80), the combustible vapor sensor (14) is in air flow communication with a surface (84) of the liquid (80). Alternatively, or additionally, an electrolyte sensor (88) can be immersed in or otherwise in fluid flow communication with the liquid (80) to detect electrolyte (86) escaping from the cell (12) which electrolyte (86) would, if exposed to air (24), become a combustible vapor (22). |
