ExSorbtion Inc.

ExSorbtion’s mission is to become the highest-value supplier of lithium to enable electrification of everything. ExSorbtion has acquired and is commercializing a technology developed by SRI International. This technology portfolio includes patented sorbents that have demonstrated very high lithium selectivity, fast reaction time to adsorb lithium from the brine and to remove lithium from the sorbent. The patented regeneration process uses carbon dioxide gas instead of acid (which is used by all other DLE companies) to extract the adsorbed lithium from the sorbents. By using gas instead of acid, ExSorbtion’s sorbents last >10x longer than competing manganese- and titanium-based sorbents – which is important since cost of the sorbent is >30% of the overall cost of goods sold for the DLE process, enabling potentially the lowest operating cost compared to other DLE process. Additionally, since the process uses carbon dioxide gas for regeneration, the process basically acts as a carbon sink making it the greenest DLE process, while consuming significantly lower amount water for each ton of lithium carbonate produced which is >60% lower than competing DLE processes.
