Without an incorporated LiSX™ circuit conventional electrolysis of Li2SO4, has no use for a H2SO4-Li2SO4 solution and has to employ a 3 compartment cell to separate H2SO4/Lean Li2SO4/LiOH. LiEL together with LiSX™ eliminates the third compartment as well as allowing operation at higher Li concentrations, resulting in a smaller, cheaper, more efficient electrolysis operation.
