===Lithium ion polymer (lithium polymer)===


===Positive characteristics===

•	No voltage depression ("memory" effect).


•	Even higher storage density than lithium ion (up to 300% of NiCd storage density).


•	Doesn't have to be in a cylindrical shape.


•	Environmentally friendly.

===Negative characteristics===


•	Must not be over discharged.


•	Reduced capacity under heavy loads (Peukert Effect).


•	Can be recharged "only" a few hundred times (less than NiCd or NiMH).
