Abstract: A mobile system (100) for treating an accumulator, a battery, a cell and/or a vehicle that includes an accumulator, a battery, a cell. The system is arranged on a mobile vehicle, e.g. a truck, a trailer, the system comprising at least one container/reactor (101) in which the pressure can be increased from 2 to 40 bar, and the container/reactor having at least one door (102) for hermetically opening and closing the container/reactor (101), a heating element/device 110 for raising the temperature inside the container/reactor to at least 100° C. and at least one H2O supply.

Abstract: A protective housing (100) for batteries, accumulators and electrical cells, with a body (101) which forms a chamber (105) for accommodating the battery, accumulator and/or electrical cells. The housing has at least one chamber, wherein this chamber extends over at least one surface forming at least one wall of the housing and forms a cavity to receive water therein. The cavity has at least one one-way valve for relieving excess pressure and an inlet channel for filling the cavity with water, and the chamber has at least one connection via an electrical cable (107) to the outside of the housing (100) and at least one inner surface (109) of the housing forming the cavity in which the thermally conductive water is present.

Abstract: A method for processing accumulators, batteries and the like, which contain lithium, lithium ions, sodium, potassium and/or nickel as active components. According to the invention, the following steps are carried out; —introducing an accumulator, a battery, cell or the like, that contains lithium, lithium ions, sodium, potassium and/or nickel, into a chamber/reactor (13,23); —introducing water (H2O) (B, B2) in to the reactor (13,23); bringing the content of the reactor (13) to a temperature between 120° C. and 370° C. at a pressure between 2 and 250 bar.
