However, Roskil points out that the membrane used in the experiment had a diameter of ~ 20 mm with a thickness of ~ 55 μm and was reported to be particularly brittle. This means that the growth of the thin membrane, which is crucial for the extraction of the process, can create a barrier to commercial operations.
In addition, the analyst highlights the fact that the seawater sample used, from the famous salty Red Sea, will not be representative of water from many other seas and oceans.
Despite these observations, Roskil says that the method for producing lithium phosphate from brine obtained from seawater containing 0.9% Li may have other applications.
“While seawater is a potential new source of lithium, the process can provide greater use in the purification and improvement of higher concentrations of lithium brine from continental or geothermal sources,”
