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).
What is a lithium electrolyte?
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.
Why is Filter selection important in filtering slurries?
When filtering slurries, filter selection is critical. The filter must allow the desired particles to pass through, while simultaneously retaining oversized particles. This must be accomplished without plugging the filter and consequently shortening its service life.
How does a slurry filter work?
As the fluid goes through the filter, the pores become finer, removing ever smaller oversized particles. Because of the filter's very sharp particle size cut-off, virtually all of the desired active slurry material is able to pass through the filter.
