与插层型锂离子电池（LIB）相比，转换型锂硫（Li-S）电池因为其高理论能量密度（2600 Wh kg-1）而受到越来越多的关注。但是，多硫化物穿梭效应、缓慢的反应动力学和锂金属枝晶生长等问题阻碍了锂硫电池的进一步应用。硫正极的多步转化反应涉及电极/电解质之间一系列Li+的交换，这些反应也亟需克服脱溶剂和电荷载体扩散的能量势垒，这导致了缓慢的转化动力学以及多硫化物中间体的积累。

浮萍 木糖 混合营养生长 封面论文 正式发表
2023/3/21
浮萍在污水修复和生物能源等方面具有应用潜力。自养浮萍由于受CO2和光的限制，生长速率及生物量较低。相比之下，混合营养浮萍可以同时利用光合作用和外源有机碳，代谢具有灵活性，生长速率远大于自养浮萍。然而，在混合营养条件下，外源有机碳的添加会增加浮萍生产成本。因此，混合营养浮萍的规模化培养需要选择经济上可行和环境上可持续的有机碳源。
