一般描述

我们竭诚为您带来符合一项或多项绿色化学12项原则要求的绿色替代产品。该产品为增强型，提高了能源效率。点击此处以获取更多信息。
碘化锂被广泛用作染料敏化太阳能电池和Li-S电池的电解质添加剂，因为它可以延长循环寿命。它可作为磷光体用于中子检测。

应用

碘化锂（LiI）可用于电解质添加剂：

  • 制备可生物降解的聚合物电解质。大米淀粉与LiI复合物提高离子电导率，是因为LiI的添加增加了移动电荷载体的数量。
  • 对于Li-S电池，LiI在阳极和阴极表面都形成了保护膜，并组织多硫化物在阴极侧溶解，这显著提高了电池倍率性能。
它还可用于制备Li-基闪烁体，该闪烁体具有增强的热中子检测效率。

Lithium Iodide (LiI) is reported as a promising electrolyte additive for lithium-sulfur batteries. It induces formation of Li-ion-permeable protective coatings on both positive and negative electrodes, which prevent the dissolution of polysulfides on the cathode and reduction of polysulfides on

All-solid-state lithium batteries (ASSLBs) based on sulfide solid electrolytes (SEs) have received great attention because of the high ionic conductivity of the SEs, intrinsic thermal safety, and higher energy density achievable with a Li metal anode. However, studies on practical

Dye-sensitized solar cells (DSCs) with long-term stability are produced using polymer-gel electrolytes (PGEs). In this study, we introduce the formation of PGEs using in situ gelation with poly(methyl methacrylate) (PMMA) particles and graphene fillers that are pre-deposited on the counter electrodes.

Three-dimensional (3D) hierarchical nanoscale architectures comprised of building blocks, with specifically engineered morphologies, are expected to play important roles in the fabrication of 'next generation' microelectronic and optoelectronic devices due to their high surface-to-volume ratio as well as opto-electronic properties.

Chemistry, an Asian journal, 10(9), 1932-1939 (2015-07-15)
Mesoporous cobalt sulfide nanotube arrays on FTO-coated glass were synthesized by combining three simple technologies: the selective etching of ZnO sacrificial templates, mesoporous Co3 O4 formation from cobalt-chelated chitosan, and ion-exchange reaction (IER). The mesoporous Co3 O4 nanotubes composed of
