海洋占地球水资源总量的97%,地表面积的70%以上。随着化石燃料等不可再生能源的持续消耗与可再生能源的快速发展,人们对海洋资源的利用越来越重视。海洋能包括潮汐能、波浪能、温差能和盐差能等。其中盐差能是海水和淡水相互作用产生的能量,是以化学能形式存在的海洋能,这种能量较多产生在河口处。目前,压力延迟渗透技术、反电渗析技术和电容混合技术是转换盐差能的三种主要技术。本文构建了一种基于电容混合技术的新型盐差电池,使用二硫化钼和多壁碳纳米管复合物电极作为阳极,活性炭作为阴极。将两种不同离子储存机制的材料复合在一起,二硫化钼具有类似石墨烯的层状结构,层间间距约为石墨烯的两倍,是一种可以与钠离子发生插层反应的电池电极材料。多壁碳纳米管具有典型的双电层效应,放电时在其表面吸附钠离子的同时,可以帮助钠离子更快地进入二硫化钼层间,加快离子传输效率和盐差能的转换效率。对该复合材料进行物理和电化学表征,并与活性炭电极组装的盐差电池,测试其盐差能转换能力。浓度响应电压150 mV,经过一个完整的四步循环后,转换能量密度可达6.96 J·g^(-1)。该器件原材料价格较低,并且不使用离子膜,更加环保,为转换盐差能的研究提供了一种新途径。

Constructing a smart polymer film with favorable lithium（Li） transport capability and mechanical flexibility for suppressing Li dendrite growth is an effective strategy. Unfortunately, the porosity and the swelling of the polymer membrane cannot completely prevent liquid electrolyte from sweeping through the artificial protection film, severely deteriorating the cyclic performance. Herein, we propose a defectfree hybrid film that consists of Li+conductive lithium polyacrylate（LiPAA） polymer interface layer and Li-Zn alloy patch to tackle the critical problems of traditional polymer composite passivation film. The pinhole leaks of the polymer matrix are self-filled by Li-Zn alloy patches, enhancing the integrity of LiPAA film. Consequently, a defect-free hybrid film is nailed flat against the Li metal anode, exhibiting extraordinary stability in the liquid electrolyte and enabling perfect protection effect. This facile strategy produces a promising anode for next generation Li batteries.
