The optimum coordination structure of nickel-fluoro complexes for the preparation of Ni-Al layered double hydroxide(LDH) by liquid phase deposition(LPD) process and the diverse anion exchange properties of as-deposited Ni-Al on ・-alumina powder were quantitatively evaluated for the industrial application of new positive material for alkali secondary batteries. The [NiF6-x-y(NH3)x(OH-)y]n+ was more suitable than [NiF6]4- as the precursor of the deposition of Ni-Al LDH in the LPD reaction, and the improved LPD reaction achieved the synthesis of high purity and high crystallinity Ni-Al LDH. All anion-exchanged Ni-Al LDHs for OH--, Cl--, SO42--, and CH3COO--forms kept the high crystallinity and showed the enlargement of interlayer distances. The tilting angle of the intercalated CH3COO- anions was about 15°. Anion-exchange capacity remained constant at a minimum of 0.8meq g-1in pH >10, increased as pH decreased, and reached a maximum of8 meq g-1at pH 2. Anion-exchange of OH--form of Ni-Al LDH was accelerated by the neutralization of hydroxide ions in interlayers, in addition, the anion-exchange capacity and the crystallinity of Ni-Al LDH could be controlled by the amount of doped aluminum ions.

通过液相沉积（LPD）过程制备Ni-Al分层双氢氧化物（LDH）的最佳配位结构，以及在・-铝粉末上的ni-aposed Ni-al的不同阴离子交换特性的不同 - 铝粉末的不同型 - 用于新的阳性材料的工业应用。 [NIF6-X-Y（NH3）X（OH-）Y] N+比[NIF6] 4-作为LPD反应中Ni-Al LDH沉积的前体，而改善的LPD反应可实现高纯度和高结晶度NI-AL LDH的合成。所有用于OH-，CL-，SO42-和CH3COO的Ni-Al LDH的所有ni-al LD​​HS和CH3COO-形式保持高结晶度，并显示了层间距离的扩大。插入的CH3COO-阴离子的倾斜角约为15°。 Anion-exchange capacity remained constant at a minimum of 0.8meq g-1in pH >10, increased as pH decreased, and reached a maximum of8 meq g-1at pH 2. Anion-exchange of OH--form of Ni-Al LDH was accelerated by the neutralization of hydroxide ions in interlayers, in addition, the anion-exchange capacity and the crystallinity of Ni-Al LDH could be controlled by the掺杂铝离子的量。
