Power Battery Application Fields
The automotive and motorcycle industries—primarily providing electrical power for engine starting, ignition, and the operation of onboard electronic devices;
The automotive and motorcycle industries—primarily providing electrical power for engine starting, ignition, and the operation of onboard electronic devices;
Industrial power systems. Used in substations for transmission and transformation, providing closing current to power units, supplying backup power for public facilities, and serving as a power source for communications.
The electric vehicle and electric bicycle industries—replacing gasoline and diesel as the power sources that propel electric vehicles or electric bicycles.
Lithium-ion power battery
Lithium-iron batteries are a new type of green, high-energy chemical power source that was introduced and successfully commercialized by the U.S.-based Eveready Company after 2000. They have demonstrated exceptionally superior performance when used in electronic devices and electric toys requiring high energy and high power. At medium to high discharge currents, lithium-iron batteries can deliver up to about six times longer runtime compared to alkaline-manganese batteries. Moreover, when compared to nickel-metal hydride batteries, lithium-iron cells offer more stable discharge voltage and significantly longer shelf life.
Overall, lithium-iron batteries have the following outstanding advantages:
1. Interchangeable with alkaline-manganese batteries—can be used interchangeably with alkaline zinc-manganese batteries for any application;
2. Features longer working hours and a higher, flatter operating voltage, especially during discharges at medium currents or above;
3. Eco-friendly, green power supply—does not use any toxic substances such as mercury, chromium, or lead;
4. Excellent storage performance—can remain stable for up to 10 years.

Nickel-metal hydride rechargeable battery
Since cadmium in nickel-cadmium (Ni-Cd) batteries is toxic, making waste battery disposal complicated and posing risks of environmental contamination, these batteries are gradually being replaced by nickel-metal hydride (Ni-MH) rechargeable batteries made from hydrogen-storage alloys. In terms of battery capacity, Ni-MH batteries of the same size typically deliver 1.5 to 2 times more power than Ni-Cd batteries—and crucially, they eliminate the risk of cadmium pollution. As a result, Ni-MH batteries are now widely used in various small, portable electronic devices, such as mobile communication devices and laptop computers. Nickel-hydrogen batteries are composed of hydrogen ions combined with metallic nickel, offering a 30% greater energy storage capacity compared to Ni-Cd batteries. They are also lighter, have a longer lifespan, and cause no environmental harm. Moreover, larger-capacity Ni-MH batteries have already begun to find applications in gasoline-electric hybrid vehicles. Leveraging the fast charge-discharge capabilities of Ni-MH batteries, when the car is traveling at high speeds, electricity generated by the onboard generator can be stored directly in the vehicle’s Ni-MH battery pack. Conversely, during low-speed driving—when fuel consumption tends to spike compared to high-speed conditions—these batteries can power the electric motor, effectively replacing the internal combustion engine. This innovative approach not only ensures smooth vehicle operation but also significantly reduces fuel consumption, helping to conserve resources while maintaining performance.
