- the lithium battery is a lithium-ion battery.
- FIG. 1 there schematically illustrates a cutting chamber equipped with a battery and a cutting fluid injection nozzle.
- the process of dismantling a lithium battery illustrated in comprises a first step S1 of supplying the lithium battery followed by a step S2 of cutting the lithium battery using a jet of pressurized liquid.
- the purpose of step S2 of cutting the lithium battery is to open the lithium battery in order to allow access to the internal components of the battery to separate the different components. Access to the battery components makes it possible, for example, to separate lithium from other battery constituents, for example polymer compounds, noble metals, iron or steel assembly parts. This also helps extract solvents from the battery.
- step S3 which consists of separating the constituents of the cut battery and the cutting liquid.
- the cutting of the battery 1 is carried out in a cutting chamber 2.
- a nozzle 3 is supplied by a tank 4 which contains the liquid.

- Battery cutting step S2 uses a high-pressure liquid jet.
- the liquid has at least one component which is in the liquid state.
- the liquid may contain abrasive particles or be devoid of abrasive particles.
- the liquid used for cutting the battery may contain a single component in the liquid state or it may contain a mixture of several components in the liquid state.
- the liquid is devoid of water.
- Water is a compound that will react with one or more constituents of the battery. This reaction can be exothermic, which poses a risk of burns or explosion. Water can also degrade one or more battery components. It is therefore particularly advantageous not to use water to cut the battery to avoid damaging the multiple components of the battery. Cutting the battery makes it possible to avoid using a mechanical manual opening. It is also advantageous to provide that the cutting liquid is free of ionic liquid.
- the liquid used for cutting the battery only contains liquid components which do not react with lithium and even more preferably only liquid components which do not react with the constituents of the battery.

- the first component is in the liquid state, but the first component can also be in the gaseous state under temperature and pressure conditions which are not considered harmful to battery constituents.
- the first component is chosen to appear in the gaseous state under normal conditions of temperature and pressure (0°C, 101325Pa).
- the component in the liquid phase consists solely of at least one first component.
- the dismantling process includes a transformation of the first liquid component so that the first liquid component changes to the gaseous state after cutting the lithium battery.
- first component which can be in the gaseous state under temperature and pressure conditions such that the majority or all of the constituents of the battery are in the liquid state or in the state solid makes it possible to facilitate the dissociation between the liquid component or the majority liquid component of the cutting fluid which has changed phase and the constituents of the battery.
- the cutting fluid When cutting the battery, the cutting fluid is ejected from the nozzle under temperature and pressure conditions which ensure that the first component is in the liquid state at the outlet of the nozzle and that it reaches the battery at the liquid state.
- the cutting fluid is ejected from the nozzle at high pressure and possibly at low temperature to ensure that it is maintained in the liquid state. It is advantageous to eject a liquid whose temperature is between -56°C and -80°C at 1013hPa.
- the cutting of the battery is carried out in a chamber whose temperature and pressure conditions correspond to at least one first component in the gaseous state.
- the first liquid is ejected from the nozzle in liquid state, it hits the battery in liquid state with enough energy to cut the battery.
- the heating of the cutting fluid when cutting the battery allows at least part of the first component to pass into the gaseous state.
- the first component which has passed into the gaseous state during cutting advantageously remains in the gaseous state in the chamber. This configuration makes it possible to limit thermal and mechanical constraints on the cutting chamber.
- the first component in the liquid state that reaches the walls of the cutting chamber can remain in the liquid state or can change to the gaseous state.
- the first liquid component transforms at least partially into gas in contact with the battery, which preferably allows the atmosphere of the chamber to be partially or completely filled with a gas. which is inert with respect to the constituents of the battery.
- a transformation step from the liquid state to the gaseous state of the first component is carried out, for example for the portion which did not heat up enough when cutting the battery.
- the transformation can be achieved with an increase in temperature and/or a decrease in pressure in the chamber.
- the pressure in the chamber is reduced in order to balance with the pressure outside the chamber and which is preferably between 90000Pa and 110000Pa, preferably the atmospheric pressure, approximately 101325Pa depending on the altitude and the weather situation. It is also possible to increase the temperature inside the chamber and it is best not to exceed 50°C.
- the cutting chamber is filled with a first gas, a pure gas or a gas mixture before starting the cutting operation and preferably when introducing the battery into the cutting chamber.
- a first gas a pure gas or a gas mixture
- the first component in the gaseous state is denser than the first gas in order to surround the parts of the battery resulting from the cutting.
- the at least one first component comprises carbon dioxide.
- Carbon dioxide does not interact with lithium so it will not cause the degradation of carbon, for example the combustion of lithium.
- the interaction of carbon dioxide with the other constituents of the battery is low or non-existent, which facilitates their recycling.
- the at least one first component comprises mainly carbon dioxide by volume, or even the at least one first component comprises exclusively carbon dioxide.
- the first component is chosen from carbon dioxide, argon and helium. Carbon dioxide is preferred because it is cheaper.
- the first component is free of dinitrogen or any other molecule capable of forming liquid nitrogen under the conditions of application of the liquid jet. It has been observed that nitrogen can form very reactive compounds with lithium particles such as lithium azides (LiN3) and lithium nitrides (Li3N). Lithium azides decompose violently when the liquid phase is heated and can give rise to toxic compounds. The same is true for lithium nitrides.
- the process for dismantling a lithium battery comprises, after cutting the lithium battery, recovering the at least one first component in the gaseous state and compressing the at least one first component to place it in the liquid state in the tank for a new cutting cycle of a new lithium battery.
- the material used to cut the battery is passed into the gaseous state in order to be dissociated from the constituents of the battery then is compressed to pass into the liquid state and be reused for a new battery which reduces the consumption of first component.
- a first component which is denser than air for example carbon dioxide.
- air we mean a gas mixture that contains at least 75% nitrogen and 20% oxygen.
- the cutting of the lithium battery is carried out in a chamber, the chamber being devoid of oxygen before initiating the cutting.
- the cutting of the lithium battery is carried out in a chamber, the chamber being devoid of nitrogen before initiating the cutting.
- the chamber is mainly filled in volume with the first component in the gaseous state.
- the process for dismantling a lithium battery includes a step S3 of recovering the battery parts, the battery parts being dry after cutting the battery.
- the first component having been transformed into the gas state, the constituents of the battery can be used immediately for the next recycling stage.
- the liquid component only includes the first component, the transformation of the first component from the liquid state to the gaseous state makes it possible to carry out dry sorting of the constituents of the battery.
- the cutting fluid has abrasive particles, there is dry sorting between the abrasive particles and the constituents of the battery.
- the component in the liquid state comprises at least a second component which is in the liquid state under normal conditions of temperature and pressure and/or at 20°C and at 101325Pa.
- the second component has a boiling temperature greater than 120°C, advantageously greater than 150°C. the second component is intended to be mainly or exclusively in the liquid state throughout the cutting stage and until the recovery of the battery constituents.
- a second component which has a saturated vapor pressure which is low, for example less than 50 Pa at 20°C.
- the second component has little or no reactivity with the constituents of the battery.
- the component comprises only the first component, only the second component or a mixture between the first component and the second component. Even more preferably if the battery is cut simultaneously by means of the first component and the second component, the first component is sent by means of a first nozzle and the second component is sent by means of a second nozzle.
- the second component comprises at least one second component chosen from ethylene glycol, propylene glycol or a mixture of these.

- the jet of liquid comprises polyetheramines, to neutralize battery acid.
- a possible polyetheramine for neutralizing an acid is marketed by the company Huntsman International under the name Jeffamine®.
- the use of a polyetheramine is advantageous in combination with the first and/or the second component.
- the use of polyetheramines is particularly advantageous when the battery includes a lithium hexafluorophosphate salt. It is particularly advantageous to use a polyetheramine which has a saturated vapor pressure of less than 50Pa at 20°C and a flash point temperature which is greater than the temperature of the second component, preferably greater than 110°C or even greater than 150°C. vs.
- polyetheramines is particularly advantageous in association with the second component chosen from alkyl glycol because the properties of the polyetheramines do not degrade the performance of the alkyl glycol.

- Silicon carbide can be used in the ⁇ form which crystallizes in a hexagonal system or in its ⁇ form which crystallizes in a face-centered cubic system. These two forms are stable in the aforementioned temperature range. It also appears that these two forms are chemically stable in a temperature range from -100°C to +1000°C.
