the cell exhibits 346.7mAhg1 first discharge capacity and the specific capacity maintains at 112mAhg1 after 200 cycles at a current density of 50mAg1, which is superior to that with non-nucleophilic Mg(HMDS)2-(AlCl3)2-MgCl2+LiTFSI/DME (HMDS-based) and MBA-(MgCl2)2-(AlCl3)2+LiCl/THF ...
b)在-1.0至4.0V(vs Mg)的电势范围内,在5mV s-1的扫速下,BCM电解质中Mg剥离/电镀的第二(上)和第三(中间)CV循环曲线以及各种电极的LSV曲线(下侧)。 c)计算的四个阴离子的HOMO和最低未占分子轨道(LUMO)能级; (从左到右:[TrHB]-,[FTHB]-,[HMDSAlCl3]-和[Al(Ph)4] -)。 图五: Mg沉积物的表征...
HMDS基液态电解质由Liebenow等人于2000年提出,如六甲基二硅胺基氯化镁(HMDSMgCl)在THF溶剂中具有5.8×10−4 S cm−1的电导率和2.4 V vs. Mg/Mg2+的氧化稳定性,HMDS基电解质的非亲核特性使其可与S基正极相结合应用于高能量RMBs。 图4.(a)使用Pt作为工作电极的0.25 M MACC溶液(二甲醚作为溶剂)中的LSV...

In order to improve the compatibility between Mg anode and electrolyte, various electrolyte systems have been developed, ranging from nucleophilic electrolytes (based on Grignard reagents) [15,87] to non-nucleophilic (APC [87,88], hexamethyldisilazane (HMDS)-based [[89], [90]], magnesium aluminu...
(MOF)-derived sulfurization method and compare its electrochemical performance as a displacement reaction cathode of hybrid Mg2+/Li+ batteries with 0.4 mol L-1 (PhMgCl)(2)-AlCl3+1.0 mol L-1 LiCl/THF nucleophilic hybrid electrolyte and 0.2 mol L-1 Mg(HMDS)(2)-(AlCl3)(2)-MgCl2+1.0 mol...
