NiMH No. 7 battery

What are the characteristics and advantages of NiMH No. 7 battery phosphate batteries?

The new generation of electric vehicles uses a new type of NiMH No. 7 battery phosphate battery as its power core. This green and environmentally friendly power has many characteristics and advantages:

1. High safety

As a car power, safety is the overriding primary consideration. Although the safety of ordinary lithium-ion batteries can be basically guaranteed, there is a possibility of fire and explosion under extreme conditions. As the second-generation product of lithium-ion batteries, NiMH No. 7 battery phosphate batteries have stable physical properties. Combined with the built-in overvoltage, undervoltage, overcurrent, overcharge and other protection functions of the battery pack, they will not explode or catch fire. They are currently the only absolutely safe lithium-ion batteries in the world. Due to the use of high thermal stability materials and meticulous process design, battery safety and reliability are greatly enhanced. Compared with the explosion phenomenon that may occur in the improper use of lithium-ion batteries, NiMH No. 7 battery phosphate batteries will not explode even if thrown into the fire. The high temperature stability can reach 400500C, which ensures the inherent high safety of the battery; it will not explode or burn due to overcharging, high temperature, short circuit, and impact. After strict safety testing, it will not explode even in the worst traffic accidents.

2. Long life and low cost

As a power lithium battery, the service life (cycle performance) is closely related to the overall cost of use. Compared with the cycle life of ordinary lithium-ion batteries of about 500 times, NiMH No. 7 battery phosphate batteries can be charged and discharged for 1,500 times at room temperature, with a capacity retention rate of more than 95%, and a cycle life of 50% capacity of more than 2,000 times. The battery's continuous mileage life is greater than 500,000 kilometers and can be used for about five years, which is 8 times that of lead-acid batteries, 3 times that of nickel-hydrogen batteries, and about 4 times that of cobalt-acid lithium-ion batteries. In addition, its production and manufacturing cost is lower than that of ordinary lithium-ion batteries, which can undoubtedly greatly reduce the use and maintenance costs of electric vehicles.

At the same time, the discharge performance of NiMH No. 7 battery phosphate batteries is also very excellent, with a stable power curve and strong anti-over-discharge ability. Ordinary lithium batteries are over-discharged after being discharged below 3.2V, which may lead to scrapping. However, NiMH No. 7 battery phosphate batteries still release energy at 2.8V, and there is no problem of scrapping below 2.5V.

3. Easy to use and handle

We understand that nickel-metal hydride and nickel-cadmium batteries have strong memory effects, and ordinary lithium-ion batteries also have certain memory effect problems. Trying to fully charge and discharge them will bring inconvenience to the daily use of electric vehicles, while NiMH No. 7 battery phosphate batteries do not have this phenomenon, with low self-discharge and no memory effect. No matter what state the battery is in, it can be charged and used at any time, without having to discharge it first and then charge it. At the same time, the battery has excellent fast charging characteristics, and can be fully charged to about 95% in half an hour with a special charger. The problem of handling after the end of battery life is also worthy of our attention. NiMH No. 7 battery phosphate batteries do not contain any heavy metals and rare metals, are non-toxic, pollution-free, and comply with regulations. They are absolutely green and environmentally friendly batteries. There is a lot of lead in lead-acid batteries. If they are not handled properly after being discarded, they will cause secondary pollution to the environment. NiMH No. 7 battery phosphate materials are pollution-free both in production and use.
