Ni-mh battery is how to work?

Source: 2020 - 04 - 04 o hits: how time nimh batteries work nimh batteries battery is a kind of excellent properties. Nickel metal hydride batteries are divided into high pressure low nickel metal hydride batteries and nickel-metal hydride batteries. Nickel metal hydride battery cathode active material of Ni ( 哦) 2 ( NiO metal electrode) , the cathode active material for metal hydride, also known as the hydrogen storage alloy ( Metal electrode is also called the hydrogen storage electrode) In 6 mol/L, electrolyte potassium hydroxide solution. Nickel metal hydride batteries as an important direction of the hydrogen application, more and more get people's attention. The advantages of nimh batteries 1. 2 good safety performance and stability of the records. Power density 30 ~ 40% higher than the nickel cadmium battery. Allow a longer running time or reduce the size of the battery pack. Nickel metal hydride battery system has high development potential. 3. High power density. 4. Green, not adding heavy metals. 5. The premise of concise warehousing logistics transportation logistics transportation not restricted by safety regulation 6. Be remembered more easily than the nickel cadmium battery. 7. There are various sizes of products to choose from 8. This standard specifies low self-discharge, high rate and high rate discharge, continuous high temperature and wide temperature structure unique consumption structure. 9. 2 VPC means that the battery voltage is very easy to change. 10. 11 provides simple battery solutions. Once the battery does not need to install complex PCB electronics defect 1 of nimh batteries. New organic chemical antioxidants improve self-discharge, but at the expense of lower power density. 2. If stored under constant high temperature, the performance will decline the NiMH should be stored in shady and cool place, the battery power is about 40%. 3. 20% more expensive than nickel-cadmium batteries nickel metal hydride batteries, vision for the high current consumption, is more expensive than general models.
