Abstract
본 발명은 수산화니켈을 포함하는 플러스극을 구비한 알칼리2차전지 및 알칼리2차전지의 제조방법에 관한 것으로서, 본 발명에 따르면 수산화니켈입자표면에 코발트계 피막을 부착시킨 경우 수산화니켈입자에 있어서, 보존중에 상기 코발트계 피막의 금속코발트 또는 코발트화합물이 산화되는 것을 억제 내지 방지하여 코발트 본체의 특성을 발휘할 수 있고, 상기 복합수산화니켈입자를 활물질로 하는 플러스극의 이용률의 향상이 꾀해진 알칼리2차전지가 제공되고, 본 발명에 관련되는 알칼리2차전지는 플러스극 활물질을 포함하는 페이스트를 집전체에 충전함으로써 형성된 플러스극과, 마이너스극과, 알칼리전해액을 구비하고, 상기 플러스극 활물질은 수산화니켈을 주성분으로 하는 입자의 표면에 산화방지제를 함유하고, 또한 금속코발트 및 코발트화물물로부터 선택된 적어도 한종류로 이루어지는 코발트계 피막을 형성한 복합수산화니켈입자로 이루어지는 것을 특징으로 한다.The present invention relates to an alkaline secondary battery having a positive electrode containing nickel hydroxide and a process for producing an alkaline secondary battery. According to the present invention, when a cobalt-based coating film is adhered to the surface of nickel hydroxide particles, , The oxidation of the metal cobalt or the cobalt compound of the cobalt-based coating film during storage can be inhibited or prevented to exhibit the characteristics of the cobalt-based body and the use of the alkali nickel And a positive electrode, a negative electrode, and an alkaline electrolyte formed by charging a current collector with a paste containing a positive electrode active material, wherein the positive electrode active material comprises nickel hydroxide An antioxidant is contained on the surface of the particle as the main component, and the metal cobalt and noble metal It characterized in that bit consisting of a water storage composite nickel hydroxide particles to form a cobalt-containing film formed of at least one kinds selected from a.
