What are the applications of NiMH batteries?
- What is a Ni-MH battery
Ni-MH battery is a kind of battery with good performance. Ni-MH batteries are divided into high-voltage Ni-MH batteries and low-voltage Ni-MH batteries. The positive electrode active material of nickel-metal hydride battery is Ni (OH) 2 (called NiO electrode), the negative electrode active material is metal hydride, also called hydrogen storage alloy (electrode called hydrogen storage electrode), and the positive electrode active material of nickel metal hydride battery is Ni (OH) 2 (called NiO electrode), the negative electrode active material is metal hydride, also called hydrogen storage alloy (electrode is called hydrogen storage electrode), and the electrolyte is a 6mol / L potassium hydroxide solution. As an important aspect of hydrogen energy application, nickel-metal hydride batteries have attracted more and more attention.
- What are the applications of NiMH batteries?
1.Electrical equipment: vacuum cleaner, power meter, automation control, surveying and mapping instrument
- Home portable: portable blood pressure, blood glucose tester, multi-parameter monitor, massager, portable DVD, etc.
- Lighting: searchlight, flashlight, emergency light, solar light
- Electronic toys: aircraft model, remote control car, remote control boat
- Electric tools: electric drill, electric planer, electric saw, electric batch
- Consumer electronics
Ni-MH batteries are widely used in consumer electronics.
The old nickel-metal hydride battery will lose its power within months or even weeks after charging due to self-discharge. It can only be used in applications that require power for a short period of time. Such as the infrared remote control of household appliances or clock is not suitable.
New low-leakage nickel-metal hydride batteries can basically replace most of the uses that originally used alkaline electricity. It is only some older and low power consumption electronic products (such as old radios) that suffer from voltage problems and performance will decrease when using NiMH batteries.
7.Remote control model
Some particularly powerful nickel-metal hydride batteries have larger capacity, output batteries, and power than nickel-cadmium batteries, so they have replaced nickel-cadmium batteries in electric remote-control toys (such as remote-control cars).
- Hybrid vehicles
High-power nickel-metal hydride batteries are also used in hybrid electric vehicles. The best example is Toyota's Prius. The car uses a special charge and discharge program to make the battery charge and discharge life sufficient for the vehicle to use for ten years. Other hybrid vehicles using NiMH batteries include:
*Ford's Ford Escape
*Chevrolet Malibu at Chevrolet
*Honda Civic Hybrid
*Pure battery-powered car
Although they are heavier than lithium-ion batteries, some pure battery-powered vehicles still use nickel-metal hydride batteries, such as:
GM's Honda Civic Hybrid
Honda EV Plus
