Hydrogen absorption alloy electrode |
| 摘要 |
A negative electrode of a battery, chiefly includes hydrogen absorption alloy particles each having a surface layer. The alloy particles satisfy R 2 /R 1 >=0.004 and 5 mum<=R 1 <=20 mum, or preferably 5 mum<=R 1 <=12.5 mum, where R 1 is a half of a median diameter of the particles and R 2 is thickness of the surface layers.
