Battery separator and manufacturing method thereof, and alkali secondary battery having the separator incorporated therein |
摘要 |
There is provided a battery separator comprising synthetic resin fibers, wherein hydrophilization treatment, preferably plasma treatment is applied, and a contact angle to pure water indicates a value of 0 to 100 degrees; an alkali secondary battery in which a electrode group having the separator between a positive electrode and a negative electrode is sealed in a battery case together with an alkali electrolyte, in particular, a nickel-metal hydride secondary battery whose positive electrode is a nickel electrode and whose negative electrode is a hydrogen absorbing alloy electrode, wherein active substances of said nickel electrode comprising powders consisting essentially of nickel hydroxides and higher-order cobalt hydroxides formed a surface of a part or whole thereof are employed, thereby providing its superiority in both of self-discharge properties and charge and discharge cycle life performance.
