So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Chang, Qing; Luo, Zeshunji; Fu, Licai; Zhu, Jiajun; Yang, Wulin; Li, Deyi; Zhou, Lingping researched the compound: Nickel(ii)fluoridetetrahydrate( cas:13940-83-5 ).Safety of Nickel(ii)fluoridetetrahydrate.They published the article 《A new cathode material of NiF2 for thermal batteries with high specific power》 about this compound( cas:13940-83-5 ) in Electrochimica Acta. Keywords: cathode nickel fluoride thermal battery. We’ll tell you more about this compound (cas:13940-83-5).
Transition metal halides, especially fluorides, are promising candidates used as cathode materials for primary batteries, thanks to their attractive electrochem. properties such as high conversion potential as well as extraordinary specific capacity. The intrinsic thermal stability stemming from the characteristic ionic bond, M-F, also enables them to be applied in some severe conditions. Herein, the authors study the discharge performance of NiF2 under large c.d. (0.1 A cm-2, 0.2 A cm-2 and 0.5 A cm-2), together with extremely high temperature of 520°, 550° and 580°. It can exhibit excellent electrochem. properties with the maximum specific power up to 16.2 kW kg-1 at c.d. of 0.5 A cm-2 and temperature of 550°, at cutoff voltage of 2 V (80% of the peak voltage). When the c.d. is controlled at 0.1 A cm-2, the specific power can also reach at 3.5 kW kg-1 with other parameters as the same. Afterwards, XRD and XPS are conducted to further evidence the discharge mechanism of this process, confirming it as NiF2 + 2Li → Ni + 2LiF. Based on them, probably this work will afford insights into alternatives of cathode materials in the area of high specific power thermal batteries.
In some applications, this compound(13940-83-5)Safety of Nickel(ii)fluoridetetrahydrate is unique.If you want to know more details about this compound, you can contact with the author or consult more relevant literature.
