Abstract Manganese lithium ionic sieve is one of the best lithium adsorption materials because of such advantages as high selectivity of Li⁺, large adsorption capacity and low cost. However, the sieve is superfine powder, so it is hard to adsorb continuously and realize industrialization. Aiming at this problem, different film forming conditions were studied to prepare composite membrane with lithium ionic sieve, and the structure and adsorption properties of different membrane material were also compared. Polyvinyl chloride(PVC) was used as film forming materials, N, N-dimethylacetamide(DMAC) was used as solvent. Composite membrane with lithium ion sieves was made in the method of phase inversion and was used to study the membrane condition, material blending ratio and concentration of casting solution, Li₄Mn₅O₁₂ content, film thickness and pore forming agent content on the membrane structure and the adsorption performance influence. Good conditions of PVC membrane was determined: PVC concentration of 19.05%, Li₄Mn₅O₁₂ content of 63.83%,PEG content of 2.32%. Good cycle stability and mechanical strength were presented by several adsorption-desorption experiments and mechanical properties.
