Each has its own pro's and cons. Here is a list:
-The lightest of all metals
-The greatest electrochemical potential
-The largest energy density for weight.
-The load characteristics are reasonably good in terms of discharge.
-The high cell voltage of 3.6 volts allows battery pack designs with only one cell versus three.
-It is is a low maintenance battery.
-No memory and no scheduled cycling is required to prolong the battery's life.
-Lithium-ion cells cause little harm when disposed.
-It is fragile and requires a protection circuit to maintain safe operation.
-Cell temperature is monitored to prevent temperature extremes.
-Capacity deterioration is noticeable after one year (whether the battery is in use or not).
-Lithium polymer chemistry differentiates itself from Lithium Ion in the type of electrolyte used (a plastic-like film that does not conduct electricity but allows ion exchange - electrically charged atoms or groups of atoms).
-The polymer electrolyte replaces the traditional porous separator, which is soaked with electrolyte.
-The dry polymer design offers simplifications with respect to fabrication, ruggedness, safety and thin-profile geometry.
-Cell thickness measures as little as one millimeter (0.039 inches).
-Can be formed and shaped in any way imagined.
-Commercial lithium polymer batteries are hybrid cells that contain gelled electrolyte to enhane conductivity.
-Gelled electrolyte added to the lithium ion polymer replaces the porous separator. -The gelled electrolyte is simply added to enhance ion conductivity.
Capacity is slightly less than that of the standard lithium ion battery.
-Lithium ion polymer finds its market niche in wafer-thin geometries, such as PDA batteries.
-Improved safety - more resistant to overcharge; less chance for electrolyte leakage.
