Secondly, by limiting the transmission speed, the reaction intensity of the active metal and the treatment liquid can also be controlled to prevent violent reactions and improve the safety of the device.

For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0044] In the development of battery technology, not only many design factors need to be considered, but also battery production work, such as production speed and production efficiency. Among them, safety in battery production has become one of the important obstacles to the further development of batteries.

[0045] Batteries usually include a shell, an electrode assembly and an electrolyte. The electrode assembly is an important part of the battery to complete the electrochemical process. It is usually composed of pole pieces and separators. The pole pieces include positive and negative pole pieces. The electrochemical process is mainly achieved by the movement of metal ions between the positive and negative pole pieces.

[0046] The inventors noticed that during the first charge and discharge process of the battery, a solid electrolyte interphase (SEI film) will be formed. The formation of the SEI film will consume metal ions in the pole piece. For example, in lithium-ion batteries, the formation of the SEI film will consume part of the lithium, resulting in lithium loss, thereby reducing the discharge capacity of the battery and the first charge and discharge rate. In the related art, in order to reduce the irreversible reduction of the battery capacity during the first charge process, a replenishing device is usually used to replenish active metals on the surface of the pole piece during the pole piece forming process. For example, in lithium-ion batteries, a lithium replenishing device is used to replenish active lithium on the surface of the pole piece during the pole piece forming process, thereby improving the discharge capacity of the battery and the first charge and discharge rate. In the pole piece replenishing work, a calendering process and a laminating process are usually used. The calendering process is to thin the active metal strip by rolling to form a metal film, and the laminating process is to laminate the metal film to the surface of the pole piece by rolling. The use of calendering and laminating processes for feeding will generate a lot of waste, the main components of which are a mixture of active metals and solvents, which need to be separated and processed. However, the active metals have active chemical properties, making separation and processing difficult and less safe.

[0047] In order to solve the problem of separating and processing the mixture of active metals and solvents, the inventors have found that although the active chemical properties reduce the safety of the separation process, it also means that the reaction is more likely to occur. The active metals in the mixture can be removed by reaction, and then the solvent can be separated from the reactants to achieve the recycling of the active metals and solvents.

[0048] Based on the above considerations, the inventor of the present application has designed a device for processing active metals after in-depth research.

[0049] Figure 1 A schematic diagram of the structure of an active metal processing device provided in some embodiments of the present application.

The active metal can be one of lithium, sodium, potassium, etc.

[0052] The feeding mechanism 2 is used for buffering and quantitatively providing a mixture of active metal and solvent, such as a spiral feeding cylinder, etc. The solvent can be a solvent used for passivating active metals in battery production, such as silicone oil.

[0053] The transmission mechanism 3 is used to transmit the mixture of active metal and solvent, such as a transmission pipeline. During the treatment process, the mixture of active metal and solvent is discharged below the liquid surface 13 of the treatment liquid 12. The active metal reacts quickly with the treatment to generate hydroxide and hydrogen that can be dissolved in water. The hydrogen escapes from the liquid surface 13 along the direction of the air flow. The solvent and the treatment liquid 12 are immiscible and float to the liquid surface 13 or sink to the bottom of the treatment liquid 12 according to the density relationship between the solvent and the treatment liquid 12.

[0054] By setting the discharge port 31 below the liquid surface 13 of the treatment liquid 12, firstly, the active metal can be completely covered in the treatment liquid 12, thereby promoting a full reaction between the active metal and the treatment liquid 12; secondly, the influence of the external environment, such as air, on the reaction process between the active metal and the treatment liquid 12 can be isolated; thirdly, the reaction can be placed in a liquid environment, thereby accelerating the dissipation of the reaction heat and preventing heat accumulation from causing safety problems.

One end of the main body 32 is connected to the power source 33, and the other end is set as a discharge port 31. One end of the sub-tube body 34 is connected to the main body 32, and the other end is connected to the feeding mechanism 2.

[0057] By providing a power source 33 , a driving force can be provided for the mixture of active metal and solvent to move toward the discharge port 31 . Secondly, the rapid flow of gas in the main tube 32 can also form a negative pressure, which facilitates the rapid movement of the mixture in the sub-tube 34 into the main tube 32 .

[0062] By providing the bottleneck 35, when the air in the main body 32 flows rapidly, a siphon effect can be generated at the feeding port 36, so that the mixture in the sub-tube body 34 is sucked into the main body 32, thereby effectively increasing the movement speed of the mixture. Secondly, the siphon effect generated can also make the air in the sub-tube body 34 flow, so that the mixture moves with the airflow, reducing the contact between the light active metal and the solvent and the sub-tube body 34, and preventing the light active metal and the solvent from adhering to the inner surface of the sub-tube body 34.

By setting the density of the treatment liquid 12 to be greater than the density of the solvent, the solvent can naturally float to the surface of the treatment liquid 12 and deposit at the liquid surface 13, which is convenient for subsequent separation of the solvent.

[0070] Optionally, the solvent is silicone oil.
