    Lithium ion batteries are being used in many consumer applications like cars and industrial battery solutions. These also brings host of fire and life safety challenges. I remember seeing a video on YouTube related to spontaneous combustion, explosion under mechanical stress etc. In addition, read about the toxic fumes it emits.

    Is there any safety standards available for installation, maintenance and testing of these batteries?

    One very simple safety practice (old school, down-to-earth, and minimal cost) is to not leave batteries sitting around at full charge whenever practical.  

    High Energy = High Potential Danger

    Very timely topic.  

    Thanks, Ankush, for raising it for discussion.

    Is there a risk of fire starting from a properly manufactured and physically intact ground-state (completely non-charged) Li-ion battery? I would think shipping them would be much easier if it were the case that you could have their contacts sealed after proof of discharge.

    There are two basic types of lithium-ion chemistries: cobalt and manganese (spinel). To achieve maximum runtime, cell phones, digital cameras and laptops use cobalt-based lithium-ion. Manganese is the newer of the two chemistries and offers superior thermal stability. It can sustain temperatures of up to 250°C (482°F) before becoming unstable. In addition, manganese has a very low internal resistance and can deliver high current on demand. Increasingly, these batteries are used for power tools and medical devices. Hybrid and electric vehicles will be next.

    The International Standards and Testing Applicable to Batteries are available and these are

    1. BS 2G 239:1992 for Specification for primary active lithium batteries for use in aircraft.
    2. BS EN 60086-4:2000, IEC 60086-4:2000 for Primary batteries. Safety standard for lithium batteries
    3. BS EN 61960-1:2001, IEC 61960-1:2000 for Secondary lithium cells and batteries for portable applications. Secondary lithium cells
    4. GB /T18287-2000 for Chinese National Standard for Lithium Ion batteries for mobile phones
