Direct lithium extraction + LiOH crystallization
A Salar-brine DLE train: an Al-based sorbent column selectively loads Li+ (rejecting the brine's much larger Mg2+ background — real DLE sorbents cut a ~290:1 Mg/Li mass ratio down to under 1:1), the loaded sorbent is eluted with fresh water into an aqueous strip liquor (bridging the sorption column's own documented single-pass-loading scope), RO concentrates it, a real bipolar-membrane electrodialysis (BPED) cell converts LiCl to LiOH — Faraday's law links the applied current/membrane area/current efficiency to the actual Li+ transport rate (replacing an earlier placeholder fixed-conversion reactor), reporting real cell voltage and electrical power draw — and a forward-feed two-effect evaporator train (vapor from effect 1 heats effect 2) concentrates it to battery-grade LiOH·H₂O crystals. Real boiling-point elevation throughout via the Pitzer-electrolyte brine thermo package. Isotherm parameters per the sorption column's own citation (2024 Desalination study, Al-based DLE sorbent).

Spent-battery black mass (an NMC111-like LiNi1/3Mn1/3Co1/3O2 lump, sulfuric acid-leached at a screening-level yield/stoichiometry — see the stated scope) dissolves into a pregnant leach solution carrying Li/Co/Ni/Mn. A 15-stage D2EHPA solvent-extraction circuit (the same real pH-isotherm chemistry the co-ni-solvent-extraction example uses, operated at pH 7.5 — above every curated Co/Ni/Mn pH50 — so all three transition metals extract into the kerosene organic phase while Li, which has no curated D2EHPA isotherm, stays in the aqueous raffinate untouched) purifies the liquor before it ever reaches the lithium-recovery chemistry. A Faraday's-law bipolar-membrane electrodialysis (BPED) cell (the same real electrochemistry as the direct-lithium-extraction example, sized up for this liquor's larger Li flow) converts Li+ to LiOH, which an MSMPR crystallizer takes to battery-grade LiOH solid. Every step reuses an already-real, independently-tested unit op (,,,) chained into the one train none of them had been assembled into before.
