The system for separating battery cell cores includes a cell core holder for receiving and holding a battery cell core. A cutter cuts an outer wrapping layer of the battery cell core to form an open loose end. A first roller rotates the battery cell core and a sheet opener engages the open loose end to unroll a laminate, which includes a cathode layer, an anode layer, and a polymer separator layer sandwiched therebetween. A pair of second rollers receive, grip and selectively drive movement of the laminate. A cathode breaker applies breaking force to the cathode layer to produce broken cathode layer pieces, which are then collected. An anode breaker then grasps and vibrates the laminate to produce broken anode layer pieces, which are also collected. Finally, a polymer separator layer cutter selectively cuts the polymer separator layer to produce cut polymer separator layer pieces, which are collected.

The present application provides a process to recover materials from rechargeable lithium-ion batteries, thus recycling them. The process involves processing the batteries into a size-reduced feed stream; and then, via a series of separation, isolation, and/or leaching steps, allows for recovery of a copper product, cobalt, nickel, and/or manganese product, and a lithium product; and, optional recovery of a ferrous product, aluminum product, graphite product, etc An apparatus and system for carrying out size reduction of batteries under immersion conditions is also provided.

A method for recovering valuable metals from a spent secondary battery according to an embodiment of the present disclosure includes a pre-processing process of pre-processing the spent secondary battery, a melting process of heating the pre-processed spent secondary battery to generate a molten solution, and a recovery process of recovering the valuable metals from the molten solution. In the melting process, a chlorinating agent is added, and, in the recovery process, lithium is recovered in a form of lithium dust.

An apparatus for processing a waste battery is proposed. The apparatus includes a conveying unit having a conveying belt rotated by a plurality of rotating shafts which are rotated to convey the supplied waste battery in one direction, a pulverizer disposed on a position along a travelling direction of the conveying unit to pulverize the waste battery, a heater disposed on a downstream side of the pulverizer to heat dust formed by the pulverizer, a collector collecting the dust which passes through the pulverizer and the heater, a filter part filtering a pulverized material of the collector, a mixer supplying an additive to the dust discharged from a discharge pipe of the filter part, and a compressor compressing a mixture mixed in the mixer.

A method for separating black mass from electrodes of spent lithium ion batteries includes separating electrode pieces from remainder of material of a portion of a spent lithium ion battery. The electrode pieces are heated to a temperature in a range from about 200? C. to about 350? C. for a predetermined period of time to obtain pre-heated electrode pieces. The pre-heated electrode pieces are disposed in a neutral liquid to obtain a first suspension. Ultrasound vibrations are applied to the first suspension to separate the black mass and the binder from the metal pieces. Metal pieces, binder material and black mass from the electrode pieces are then segregated to obtain black mass.

A gas injection module for separating minerals is disclosed. The gas injection module injects a gas to a supersaturated solution containing at least one mineral. The gas injection causes at least a portion of the supersaturated solution to crystallize. The supersaturated solution can be created using a clay, such as a raw Zeolite clay and a liquid (e.g., water). The Zeolite clay can contain lithium and be crushed before it is mixed with the liquid. A non-crystallizing portion of the supersaturated solution can be recirculated within the gas injection module for additional exposure to the gas and/or be processed by a reverse osmosis system.

The invention relates to a plant for recycling used batteries, comprising a comminuting device to comminute used batteries in a comminuting space. The plant includes a drying device, arranged downstream of the comminuting device, to dry the comminuted batteries. The plant includes an intermediate storage device arranged between the comminuting device and the drying device. The plant includes a stirring means to keep the comminuted batteries received in the intermediate storage space in motion. The plant includes a respective supply line for inert gas for each of the comminuting space of the comminuting device, the intermediate storage space of the intermediate storage device, and a drying space of the drying device.

This disclosure belongs to the field of battery recycling technologies, and specifically, to a battery recycling method. An example battery recycling method is disclosed including: performing split processing on a battery to obtain a metal shell and an electrode assembly, where the electrode assembly includes a roll core or a lamination; and recycling the metal shell. According to the recycling method in various embodiments of this disclosure, the battery is not wholly crushed, but the battery is split to obtain the metal shell and the electrode assembly. In other words, the metal shell obtained through recycling by using the recycling method in this disclosure is not crushed, thereby ensuring reusability of the metal shell.
