From New Atlas:
With the rise of the lithium-based battery, demand for this soft, silvery-white metal – the lightest solid element in the periodic table – has exploded. With the race to zero carbon by 2050 gathering steam, forcing the electrification of transport, lithium will be an even more valuable asset in the next 30 years.
The supply of raw materials for batteries could even end up being a national security issue, too; China's global leadership on high-volume EV production has put it ahead of the game, and while the majority of ground-based lithium reserves are in the "lithium triangle" of Chile, Bolivia and Argentina, China controls more than half's the world's supply simply through investments and ownership. It has shown in the past that it's not afraid to wield commodity supplies as a weapon.
But as with other metals like uranium, land-based lithium reserves pale in comparison to what's out there in the sea. According to researchers at Saudi Arabia's King Abdullah University of Science and Technology (KAUST), there's about 5,000 times as much lithium in the oceans as there is in land deposits, and a newly developed technology could start extracting it cheaply enough to make the big time – while producing hydrogen gas, chlorine gas and desalinated water as a bonus.
The process relies on an electrochemical cell containing a ceramic membrane made from lithium lanthanum titanium oxide (LLTO), with pores just wide enough to let lithium ions through while blocking larger metal ions. “LLTO membranes have never been used to extract and concentrate lithium ions before,” says post-doctorate researcher Zhen Li, who developed the cell....

The accompanying graphics make it look complicated but it's not really.
What is complicated is the process for extracting lithium from hard-rock spodumene. See 911 Metallurgist: Processing Spodumene by Froth Flotation for Lithium Extraction

....Now, if you will excuse me I will explore the energy intensity of roasting spodumene vs. other extraction methods. (it's pretty energy intensive, to effect the phase transformation from α-spodumene to β-spodumene you have to crank the oven up to 1050°C, then acid wash it, then roast it again at 200°C. Season to taste and wow your guests)
