Definitions

  • This invention relates generally to battery recycling. More specifically, although not exclusively, this invention relates to the recycling of lithium-ion battery materials.
  • Lithium ion batteries are widely used to power many portable electronics and electric vehicles. However, this type of battery has a finite lifetime and requires replacement after a certain period. The waste generated by lithium-ion batteries represents a significant problem for the environment if it is not recycled because lithium-ion batteries contain a number of heavy metals and toxic chemicals. Therefore, disposal in landfill may be hazardous to the environment, causing soil contamination and water pollution. In addition, there is an environmental cost to sourcing the materials required to produce lithium-ion batteries. There are also ethical concerns surrounding the mining of essential elements for use in the fabrication of lithium-ion batteries including lithium, cobalt, and nickel. Consequently, there are many benefits to recycling and re-using these battery materials including decreased environmental pollution, reduced demand on landfill, lessened demand on finite resources and decreased environmental and human costs in relation to mining virgin resources.
  • lithium-ion batteries are formed from four essential components: anode, cathode, separator and electrolyte which complete the electrochemical cell.
  • anode In order to safely package the four principal operative components it is also necessary to have a casing in which they are held.
  • various component layers may be provided (e.g. aluminium foil - cathode current collector, copper foil as the anode current collector).
  • aluminium foil - cathode current collector copper foil as the anode current collector.
  • Stabilisation is required before opening cells to prevent thermal runaway and product loss through fire. Thermal runaway is undesirable because this may lead to the synthesis and release of hot, toxic, and corrosive chemicals, and the loss of potentially retrievable components, such as electrolyte and plastic, to combustion. Stabilisation methods may include ohmic discharge, solution discharge, thermal pre-treatment, heat, electrolyte extraction.
  • Separation methods may be used to separate the components of the cell.
  • the products of separation are plastics, separator and pouch materials, metal, steel casing, Ni and Al tabs, Cu and Al current collectors, and a “black mass” (a powdery fraction formed from crushing cells containing the electrodes or from crushing the electrodes).
  • Comminution is required to disassemble the cell and to access the components.
  • Commonly used methods include shredding, milling, and/or high sheer mixing.
  • Size separation may be achieved through sieves, filters, cyclones, Magnetic separation is primarily used to remove steel casing material but can also be used to separate ferromagnetic electrode materials. Density separation is used to separate out the low density plastics and papers or high density metal casings from the mixed cell waste. This can be achieved using shaker tables, vibrating screens, a fluid of intermediate density, or air separation. Other separation methods include froth floatation, which exploits the difference in hydrophobicity between two materials, and electrostatic separation.
  • the black mass typically contains materials from the negative and positive electrodes; graphite, PVDF, carbon black, metal oxides, and some Al and Cu current collectors.
  • the black mass is reclaimed for further processing such as metal dissolution and precipitation.
  • a first aspect of the invention provides a method in accordance with Claim 1.
  • a second aspect of the invention provides a method for recycling batteries, for example lithium ion battery material, the method comprising the following steps: i. comminution of battery material, e.g. lithium ion battery material, to produce a single fraction wherein >80 wt.%, e.g. >85 wt.%, or >90 wt.%, or >95 wt.% of the pieces have a maximum dimension in the range of less than or equal to 4.0mm; ii. separating the pieces using magnetic separation.

This is in comparison to magnetic separation of a single fraction of lithium ion battery material wherein >95 wt.% of the pieces have a maximum dimension in the range of greater than 4.0mm, for example, from 4.0mm to 8.0mm.
  • the method and apparatus comprises comminution of battery material to produce a single fraction wherein >80 wt.%, e.g. >85 wt.%, or >90 wt.%, or >95 wt.% (e.g. >96 wt.%, or >97 wt.%, or >98 wt.%, or >99 wt.%, or 100 wt.%) of the pieces have a maximum dimension in the range of 1.0mm to 4.0mm. In embodiments, the pieces may have a maximum dimension in the range of any one of 1.0, 1.1 , 1.2, 1.3, 1.4, 1.5, 1.6, 1.7,

  • insulating materials may include the separator, parts of the pouch (for pouch cells) and so on.
  • the use of electrostatic separation especially with a suitable size range material, has been shown to reduce the production of fines which is beneficial from a handling perspective, and may lead to benefits insofar as a reduction of fines limits potential human exposure to deleterious materials.
