ExSorbtion Inc. is a research-driven market-focused company that is developing and commercializing a selective adsorption (or direct lithium extraction) technology for extracting lithium for from salars and oilfield and geothermal brines. ExSorbtion purchased the global patent and patent-applications portfolio of this technology from SRI International, an independent research center that has a successful track record of commercializing deep technologies working with Global 2000 corporations and launching more than 50 ventures.Our technology has demonstrated faster reaction time, higher lithium selectivity and uptake, and longer sorbent life compared to leading selective adsorption technologies. "Selective Adsorption" is a process similar to ion-exchange, wherein a brine containing lithium is passed through a bed of porous particles (sorbent), and the sorbent selectively adsorbs lithium from the brine. The adsorbed lithium is then extracted from the sorbent using regeneration and other post-processing steps.Technology Snapshot:• Demonstrated >350 cycles for sorbents at an average of 4.5 mg-Li/g-sorbent/cycle lithium uptake capacity• Demonstrated reaction time of <2 minutes for adsorption and <5 minutes for regeneration• Demonstrated selective extraction of lithium from brines with lithium concentration as low as 70 mg/L, in the presence of large amounts of Na, K, Ca, Mg, Sr and Ba• Demonstrated lithium recovery rate of 90%• Our process directly produces higher value Lithium Carbonate v/s lower value Lithium Chloride produced by other DLE processes
