The reactions that occur on the positive and negative electrodes of the MH/NI battery are all solid -phase transformation mechanisms. They do not generate and consume electrolytes. Therefore, the positive and negative poles of the battery have high stability, which can achieve sealing and maintenance exemption. Essence
MH/Ni batteries generally use the configuration method of excessive negative electrode capacity. When the battery is overcharged, the oxygen precipted on the positive pole can be restored to water on the surface of the metal hydride electrode; Metal hydrogenated electrodes absorb, so that the battery has a good ability to resist and discharge.
When the oxygen spread from the positive pole is spread to the negative electrode to react with the hydrogen, not only consumes a part of the hydrogen of the negative electrode, but affects the electrode potential of the negative electrode, and the heat released will cause the internal temperature of the battery to increase significantly, thereby accelerating the electrode reaction.
Features of nickel -hydride battery
Electric House = 1.2V
Energy/weight = 30-80Wh/kg (Wat Xiaoqing/kg), which is 108-880kj/kg
Energy/Essence = 140-300Wh/L (Wat hours/liters), which is 504-1188kj/kg (Qianjiao Er/kilogram)
Self-release rate = generally 30%per month, low self-put A high per year 15-30%per year
Charging and discharging circular and secondary application = 500-1000 times
The NII battery has a good low-temperature discharge characteristics. Even at -20 ° C's environmental temperature, a large current (with a 1C discharge rate) discharge, the discharged power can reach 85%of the nominal capacity. However, at high temperature (+40 ° C), the NI battery will drop by 5 ~ 10%. This kind of capacity loss caused by self -discharge (the higher the temperature, the greater the self -discharge rate) is reversible, and the charging and discharge cycle can be restored to the maximum capacity several times. The opening voltage of the NII battery is 1.27, which is the same as the NICD battery.
