Lithium polymer batteries

[SaintCyril]

Found a few boxes of lithium polymer batteries at a cell phone refurbishing plant, bought them for really cheap.  Does it matter if the battery id charged or not for it to work for a birch?



Some random info of lith polymer:
The Lithium Polymer battery relies on thin-film technology, with composite films that are only 100 microns thick.  It’s a solid state battery that can be wound and shaped to suite the application.  It uses a plastic electrolyte. 3M expects that a typical EV battery pack would weigh on the order of 500 pounds (224 kg), which could provide as much as 45 kW-h of energy.  In comparison, EV1’s lead-acid battery pack weighs over 1000 pounds (480 kg) and provides 16 kW-h of energy.  So we have the potential of storing nearly 3 times the energy with half the mass of today’s lead-acid batteries.

The whole point of the birch is solvated electrons.  Where would the electrons be in a dead battery?

chemistr8 - If you can show me a battery or cell that doesn't contain any electrons I'll be extremely confused!!  

All objects that you can pick up and touch are made of atoms, and these atoms have electons associated with them. When a cell is discharging, elecrons can be thought of as 'flowing' from one terminal of the battery, though the load to the other terminal. When the cell is flat it no longer has the potential to support this flow. Nevertheless, it still contains atoms and hence electrons.

i thought molecules could either have too many or too few electrons (ions?).. also, does this valence determine a chemical's solubilities?

reduction: taking electrons (Li(+) + e- --> Li)
oxidation: giving electrons (Li --> Li(+) + e-)

redox reaction: movement of electrons.
