Spodumene concentrate ore is converted into either Lithium Carbonate or Lithium Hydroxide for use as an essential component to make Lithium-Ion Batteries. Improved filtration and separation can play an important role in improving both the process reliability for producing consistent high purity products and also for improving the product yields ...
Since electrolyte constituents vary considerably among battery manufacturers, the appropriate filter needs to be determined in each case. As indicated in Figure 8, Pall has a number of different filter media that are suitable for use with battery electrolytes: polytetrafluoroethylene (PTFE), high density polyethylene (HDPE) and polypropylene (PP).
The electrolyte is typically comprised of lithium salts (e.g, LiPF6 or LiBF4) in organic solvents, such as ethylene carbonate (EC) or dimethyl carbonate (DMC). These salts may not completely dissolve in the solvents, and consequently must be removed by filtration.
The internal filter element, micron rating and efficiency are selected based on the specific operating conditions of the Li-Ion battery manufacturing process. 5-micron polyester (99+% efficient) performs well in most cases; however, different filter media, micron ratings, and efficiencies are available depending on the specific process conditions.
The electrolyte promotes the flow of lithium ions from the anode to the cathode during battery discharge and cathode to anode while the battery is charging. When filling prismatic and cylindrical cells, the dosing needle is inserted through a valve/fitting. The filling occurs in under vacuum conditions for two primary reasons:
Electrolyte filling occurs when a mixture of lithium salt in an organic solution (hexafluorophosphate LiPF6) is dosed/injected into the cell structure. The electrolyte promotes the flow of lithium ions from the anode to the cathode during battery discharge and cathode to anode while the battery is charging.
Filters are also needed to remove particle contamination during the electrolyte filling process. Since the presence of water is detrimental to the electrolyte solution, it is recommended that the carrier gas be passed through a Pall purifier to reduce moisture levels to <1 ppb.
