Project Innovation + Advantages:

The demand for lithium, a critical component of lithium-ion batteries, is expected to soar over the coming decades. As favorable sources are depleted, a new source must be tapped: recycling end-of-life lithium-ion batteries. SiTration is developing a new type of filtration membrane that is well suited to selectively extract lithium in the existing battery recycling process flow. Today’s commercial membranes are either incompatible with the harsh chemical environments of battery recycling or not selective enough to extract lithium from a complex solution. SiTration’s nanofiltration technology provides significant advantages in these areas. It can be dropped into the existing recycling process, ultimately extracting lithium more efficiently and at a lower cost.
