Solar transpiration–powered lithium extraction and storage 太阳能蒸腾驱动的锂提取和储存 ▲ 作者：YAN SONG, SHIQI FANG et al. ▲ 链接：https://www.science.org/doi/10.1126/science.adm7034 ▲ 摘要：受大自然在蒸腾作用中选择性提取物种的启发，我们报告一种太阳能蒸腾驱动的锂提取和储存（STLES）装置。该装置可以利用自然阳光从盐水中提取和储存锂。具体来说，该装置使用分层的太阳能蒸发器来产生压力梯度，从而在盐水中提取锂，并将其收集在储存层中。 长期实验、多种膜测试和不同尺寸评估证明了该材料的稳定性、兼容性和可扩展性。这种太阳能采矿技术为关键资源的可持续开采提供了另一种发展途径。 ▲ Abstract：Inspired by nature’s ability to selectively extract species in transpiration, we report a solar transpiration–powered lithium extraction and storage (STLES) device that can extract and store lithium from brines using natural sunlight. Specifically, the device uses a hierarchically structured solar transpirational evaporator to create a pressure gradient, which allows for the extraction of lithium from brines through a membrane and its storage in a vascular storage layer. Long-term experiments, various membrane tests, and different size assessments demonstrate the stability, compatibility, and scalability of STLES. This solar-powered mining technology provides an alternative developing pathway toward the sustainable extraction of critical resources. |
