In the equation, Kd [DPX] is the dynamic quenching constant (50 M− 1), Ka [ANTS/DPX] is the association constant (490 M− 1), [DPX]0 is the initial concentration of entrapped DPX, and α is the preferential release parameter. All values of α greater than zero are indicative of...

法.研究了大量N+掺杂对材料结构和电化学性能影响。结果表明,大量钠离子的掺杂会使LVP结构由单斜向菱方转变。掺杂化 合物LiNsv:(poMc存0,5c充电1c放电时,首次放电容量为118mAh·g一,50次循环后容量保持率为92.4%,并发现与单 斜INP存在多个放电平台不同,Li25N5V2(poMc仅在3.7V处有一个放电平台。
On the other hand, it should be also noted that the cold- and hot-press techniques limit the length of the tape hence they are not suitable for the mass production (in the present study, the length of the tape (~50 mm) is limited by the uniaxial-press process). Then, the ...

Labora- tory X-ray diffraction (XRD) patterns (Cu Ka radiation) of the as-prepared samples are shown in Fig. 2a. It can be seen that Ti- substituted Na0.44[Mn1-xTix]O2 (x ¼ 0.11, 0.22, 0.33, 0.39, 0.44, 0.56) maintain a crystal structure similar to their parent structure of ...
