| titleOfInvention | Iron-nickel secondary battery and preparation method thereof |
| abstract | The invention discloses an iron-nickel secondary battery and a preparation method thereof, wherein a battery plate group comprises a foam nickel positive plate, a steel strip iron negative plate and a multilayer composite diaphragm positioned between the foam nickel positive plate and the steel strip iron negative plate, the foam nickel positive plate comprises a foam nickel matrix and a positive electrode material, the positive electrode material comprises a positive active material, a positive conductive agent, a positive additive and a positive binder, the steel strip iron negative plate comprises a nickel-plated steel strip and a negative electrode material, the negative electrode material comprises a negative active material, a negative conductive agent, a negative additive and a negative binder, and electrolyte is alkaline solution containing the additive in a liquid-rich state. According to the invention, through optimization of the cathode formula, optimization of the electrolyte formula and optimization selection of the partition plate, the utilization rate of the cathode active material is improved, the internal resistance of the battery is reduced, and more importantly, the charging efficiency and the rate capability of the cathode are improved, so that the service life of the battery is prolonged. |
