Lithium ion (18650 ):

• 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 a low maintenance battery.
• No memory and no scheduled cycling are 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:

• 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.
