a Variable temperature XRD patterns of porous matrix and sorbents. b SEM images of Li-SHC with the salt content of 90 wt% in the sectional view. Scale bar: 100 μm. c EDS element mapping of Li-SHC demonstrates the uniform nanoscale arrangements of LiCl crystals and small amounts of agglomeration. Scale bar: 100 μm d Schematic illustration of the sorption-desorption process. The water molecules are captured by LiCl crystals on the surface of the fibers, then diffuse into the porous matrix, forming concentrated LiCl solution. The solution is stored inside the hydrophilic and highly porous matrix with strong capillary force. e Dynamic sorption curves of Li-SHC with the salt content of 40%, 70%, 80%, 90%, and 95%.
