Abstract Sorption-based atmospheric water harvesting has the potential to realize production anytime, anywhere, but reaching a hundred-gram high yield in semi-arid climates is still challenging, although state-of-the-art sorbents have been used. Here, we report portable and modularized harvester with scalable, low-cost, lightweight LiCl-based hygroscopic composite (Li-SHC) sorbents. Li-SHC achieves uptake capacity of 1.18, 1.79, 2.93 g −1 at 15%, 30%, 60% RH, respectively. Importantly,...
