Electrolyte With Functionalized Boron Nitride Nanosheets for Dendrite‐Free Lithium Metal Anodes
Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Lithium metal batteries (LMBs) are regarded as promising candidates for the next‐generation high‐energy‐density storage systems due to their unparalleled theoretical energy density and low redox potential. However, the commercialization of LMBs is tremendously plagued by the barbaric growth of lithium dendrite and the intricate decomposition ...

Gaoya dianqi, 1998 用预放电电流法测量了SF6气体以及SF6/CO2混合气体的正负离子迁移率。实验数据表明,正负离子迁移率只是E/p的函数,SF6/CO2混合气体的正负离子迁移率随CO2含量的增加而增大。

Dianci bileiqi, 2023 针对目前风力发电机叶尖附近空间电荷的分布特性不明确等问题，笔者利用仿真建模手段对风机叶片处于不同旋转角度时叶尖电晕放电进行了仿真研究，将风机叶片旋转时叶尖与周围空气的相对运动等效为叶尖流过的高速气流，考虑正极性离子与其他离子的附着与碰撞作用，建立了一种二维正极性电晕放电空间电荷分布模型；基于上述模型，得到了风机叶片旋转到不同角度时叶尖电晕放电正极性空间电荷的分布特性和以及正离子迁移规律。研究发现，在雷云电场作用下，由于风机叶片旋转时叶尖流过的高速气流提供给空间电荷的迁移速度远大于电场牵引力提供的迁移速度，

Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT Metal oxide semiconductor‐supported noble metal nanoparticles are common sensing materials for gas sensors. However, the large size and their tendency to migrate at high temperatures often lead to inferior sensing sensitivity and stability. Herein, a salt‐assistant strategy is developed to prepare fully‐exposed Ir clusters on SnO2 nanorods ...
