摘要

PPROBLEM TO BE SOLVED: To provide a new production method capable of inexpensively providing coated hydrogen storage alloy particles capable of realizing a nickel-hydrogen secondary battery exhibiting durability (cycle life properties) as a battery particularly at high temperature without damaging battery performance (such as service capacity and high rate discharge properties) under simple and mild conditions. PSOLUTION: Hydrogen storage alloy particles (C) subjected to catalyzing treatment are subjected to electroless composite plating treatment in a dispersed solution obtained by dispersing a titanium based compound (B) into an electroless plating solution (A) comprising a nickel ion source, thus a nickel metal-coated layer in which the titanium based compound (B) is dispersed is formed on each surface of the particles (C).

要解决的问题：提供一种能够廉价地提供涂覆的储氢合金颗粒的新生产方法，该涂覆的储氢合金颗粒能够实现镍氢二次电池作为电池，特别是在高温下具有耐久性（循环寿命特性）而不损害电池性能。（如服务能力和高倍率放电性能）在简单温和的条件下进行。

解决方案：将经过催化处理的储氢合金颗粒（C）在通过将钛基化合物（B）分散到包含镍离子源的化学镀液（A）中获得的分散液中进行化学复合镀覆处理。因此，在颗粒（C）的每个表面上形成分散有钛基化合物（B）的镍金属涂层。
