of other intermetallic elements such as Zr, Cr, Si and Mn. In general, Al-Zn-Mg-Cu alloys have high potential to recrystallize easily during deformation and subsequent heat treatments ultimately form... added to enhance the recrystallization resistance of Al-Zn-Mg-Cu alloys. On the other hand, the recrystallization of Al-Zn-Mg-Cu alloy cannot be completely suppressed by Mn, Cr or Zr addition although......
](a);狭缝喷涂法[73](b);卷对卷工艺[74](c) Fig. 10 Schematic illustration of diverse methods for perovskite solar cells, including one-step spin-coating method, two-step spin-coating method, sequential...减和电压窗口受限.为了克服这个问题,使用Ni,Mn或Co离子部分取代NaxFeO2中的铁离子形成具有更宽的充放电电压窗口的Nax[FeyM1-y]O2.在众多O3型材料中,Nax[Fe1/2Co1/2]O2显示出更稳定的电位平台和更优异的倍率性能[100].其优异的电化学性能归因于在脱钠过程中发生了O3到P3的相变,形成具有快速离子电导率的P3相.金属离子微量掺杂也可以有效稳定二元/三元金属氧化物......
