Abstract

This invention relates to a positive material of alkali batteries and a preparation method, which provides a beta-alkyl Ni2O doped with Mg, the molecular formula is Ni(1-x) MgxO(1-x)OH(1+x), X is greater or equal to 3% and smaller than or equal to 15%, in preparation, solutions of Ni2SO4, NiNO3 or NiCl is mixed with solutions of MgSO4, MgNO3 or MgCl2 to NiMg solution then to parallel-flow with alkali solution and a complexing agent to be cleaned until SO32-, NO3-1 or Cl-1 can not be tested by solution then to be filtered and dried to get MgNi2(OH)2 which is added into KOH solution and oxidant is added to be cleaned till SO42- can not be tested by BaCl2 solution then to be filtered and dried.

Description

technical field

[0001] The invention relates to an alkaline battery, in particular to a positive electrode material and a preparation method of the alkaline battery. Background technique

[0002] In recent years, with the widespread popularization of electronic products such as digital cameras, electric toys, and household appliances, higher and higher requirements have been put forward for the high-current discharge performance of batteries. However, the voltage of traditional zinc-manganese batteries drops very quickly under the condition of high-current discharge, which cannot meet the high-voltage and high-current discharge requirements of these small portable electronic devices. Thereby, there is an urgent need to develop a novel battery suitable for high-power discharge. As Zhongyin (Ningbo) Battery Co., Ltd. proposes a kind of nickel oxyhydroxide that adopts more than 80% (weight) as the active material in the patent application of CN1405908, its zinc An alkaline pri...
