Effective Separation of Li⁺/Mg²⁺ Using Cation Exchange Membrane from Brine and Water Under Electrodialysis Mustefa Ahmed Yasin*, Chen Shou Wen Abstract Sustainable energy production demands the efficient extraction of lithium ions from brines with high magnesium-to-lithium ratios for battery industries. A computational model of electrodialysis evaluates the efficiency of Li⁺
