    I have a Electrical and Mechanical Engineering degree and still battle with battery (new) technology, although I have had run ins with Li Po and Li Fe.As the mines are changing from Conventional battery packs to the new technology. Just have to careful.
    Word of advice Don't buy an unknown brand. Check!

    Hi Doug.

    Thanks for the comprehensive explanation of LiPo chemistry.

    I'm afraid that I zoned out the moment you mentioned the word 'molecule' πŸ€”
    Chemistry was never a strong subject for me at schoolπŸ™„

    "LiPo Batteries Explained."
    Sorry Martin, I dipped out as soon as I heard "twelve volts of current"!
    He also rather 'glossed over' what the polymer in Lithium polymer actually means.
    Cheers, Doug 😎
    PS Strictly speaking the correct designation of a LIPo (Lithium Polymer) accumulator (rechargeable battery)
    is 'Lithium Ion Polymer'.
    An Ion being simply a particle (atom or molecule) with an electrical charge.
    Thus the chemical processes in a Lithium-Ion and a LiPo battery are essentially the same:- i.e. transfer of Ions via the electrolyte from the + end (a Lithium compound) to the - electrode (usually carbon compound).
    The Ions are then 'tired guests' in the carbon electrode. Applying a voltage from your charger 'wakes up' the guests and sends 'em back to the Lithium electrode thus restarting the cycle.
    The basic difference is in the physical construction; Li-Ion uses a liquid electrolyte as a conduction medium and spatial separation of the + and - electrodes, whereas a LiPo contains the electrolyte (which may be held in an organic or inorganic solution so the video guy's mention of organic in an Li-Ion is irrelevant) wrapped in a polymer separator film. Usually some kind of polyethylene compound - which is a long chain Polymer plastic. Well wadda ya know, that's where the Po in LiPo comes from😁
    The separator film is micro-porous allowing the Ions through but not any larger particles from the + electrode.
    Thus they can easily be shaped into cylindrical cells (the video guy's rolled up sheet), flat pouches etc etc.
    Just follow the rules included with any LiPo battery and you'll be fine folksπŸ‘
    BTW: A slight expansion (puffing) of a LiPo when fully charged is normal, caused by some vaporisation of the electrolyte. True solid state electrolyte LiPos are still in development.

    If it looks right it probably is.

    Hi Guys,
    I just happened across this whilst doing a bit of silver surfing.
    I hope this will help to demystify the batteries that we use.
