@AmpBenzScientist how it is done? Like reusing the parts of batteries??

@thunderdragon900 Usually it's an industrial process as Lithium is not something that can be toyed with.

@AmpBenzScientist @thunderdragon900 You loose a certain percent and can knock stuff down a grade when you recycle.

@Ozzy98 @thunderdragon900 And the 110% yield fallacy appears. There will always be loss but purity and capacity don't have to be included in this statement. If I were to recycle electrical wire, I could get a higher purity than producing from regular Copper. The redemption of recycling a closed system is that the more difficult to separate contaminants are going to be in very low concentrations.

@AmpBenzScientist and if it is possible to recycle car batteries can mobile batteries also be recycled?

@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.
