Comment sont recyclées les batteries de la Prius 1: (Celles de la Prius 2 sont légèrement différentes cela change un peu les masses de chaque élément)
"To ensure that hybrid batteries are returned to Toyota, each battery has a phone number on it to call for recycling information. Salvage companies that want to get a battery recycled can present it to any Toyota dealer and receive a $150 core reward.
Toyota has been recycling NiMH batteries since the RAV4 Electric Vehicle was introduced in 1998. Every part of the battery, from the precious metals to the plastic, plates, steel case and the wiring, are recycled or processed for disposal.
At the recycler, the battery modules are separated from the wire harness, controller and metal shell (all common materials that are recycled).
Using a first generation Prius battery as an example:
After the above mentioned parts are removed, there are 89 pounds of batteries.
The plates are removed from the cases leaving 11 pounds of plastic cases and 78 pounds of plates/chemicals/and absorbent materials.
The plastic cases (Polypropylene) are recycled similar to any other consumer plastic.
Of the remaining 78 pounds, we extract 32 pounds of nickel that is sold into the steel industry as an alloy to make stainless steel, four pounds of cobalt that is used in a variety of industries -- other batteries and super alloys, and five pounds of common alloy steel (terminals and intercell connectors).
The remaining materials and chemicals are processed for recycling or disposed in an environmentally friendly fashion following local, state, and federal regulations."

Il y a donc 36% de nickel après retrait du boitier en acier et des quelques composants electriques/électroniques et conducteurs.
