A new type of nanofiber felt is proposed to address the problem of poor extraction efficiency caused by interference from other ions during the extraction of lithium ions from salt lakes using traditional powdered lithium-ion sieves.Firstly,the structure of the fiber felt was characterized,and then their properties were investigated.The results showed that the nanofiber felt prepared with a lithium ion sieve dosage of 60％can effectively adsorb lithium ions in the solution.Under these conditions,the saturated adsorption capacity of the nanofiber felt for lithium ions was 39.7mg·g-1,and the pyrolysis temperature was 340℃.After five cycles,the adsorption capacity decreased to 36.8mg·g-1,demonstrating good adsorption performance,thermal stability,and cycle recovery performance.The nanofiber felt was used for lithium extraction from actual salt lake water,and the nanofiber felt showed good selective adsorption performance for lithium ions,which can play an important role in lithium extraction from salt lakes.
