@thunderdragon900 Yes they can but it's not magic. The different Chemistries have different characteristics. These are called secondary batteries (because they can be recharged). Over time the chemical reactants become unusable. The Physics behind this is very important. It's actually Electrochemical Engineering but it's Physics (and Chemistry).

@thunderdragon900 With a simple example of a common battery, the lead acid battery, it is easier to explain just how these cells degrade. The lead exists in two forms, elemental and an oxide. Electrons flow from one electode to the other with the help of an electrolyte. Commonly the lead acid batteries die due to a single cell that brings the voltage down to an unusable level.

@thunderdragon900 the chemical energy disassociates due to entropy. This is the shortest answer. Many metals can be "won" back by an application of Electrochemistry. Unfortunately this requires the battery to be destroyed to do. It will always take energy to recycle. This is not as much of Newtown Physics as it is separating the ions. Chemistry can be used but it requires energy to produce the reagents and purity the metal.
