What are the differences between lithium battery pack and Ni-MH battery?

What is the difference between lithium battery pack and Ni-MH battery? Many consumers often have the same concept of battery usage in the process of battery use. Now lithium battery packs are the mainstream, but the past use of nickel-hydrogen batteries is still applied to lithium batteries. In fact, lithium battery packs are In addition to different products, nickel-metal hydride batteries are used in different ways. 1. The monomer voltage is different. The voltage of the lithium battery pack is 3.7-4.2V, and the voltage of the nickel-hydrogen battery is only 1.2V. The capacity of a lithium battery pack is equivalent to three nickel-hydrogen batteries in series. 2. The charging requirements for lithium battery packs are different from those for Ni-MH batteries. As the battery is fully charged, the voltage of the lithium battery pack will gradually increase, which is also a sign to determine whether the lithium battery pack is fully charged. Generally, the manufacturer recommends that the charging stop voltage is 4.2V. The charging of lithium battery packs generally adopts the voltage-limiting current-limiting method. If a friend wants to charge the lithium battery pack independently, it should be noted that its charging method is different from the constant current charging method used by the nickel-hydrogen battery. 3. Compared with nickel-metal hydride batteries, lithium battery packs have the advantages of small size, light weight, low self-discharge rate, and no memory effect, and are widely used in many new mobile devices. The batteries of mobile phones, laptops and other mobile devices that you usually use have been gradually replaced by lithium battery packs; the memory effect of Ni-MH batteries is not very obvious. Fortunately, it is sufficient after the light is released. 4. The memory effect is different. Lithium battery packs have no memory effect and can be charged as you use them; Ni-MH batteries have a certain memory effect. It is best to fully charge them in normal use, so as not to affect the battery capacity. 5. The self-discharge phenomenon is different. Although compared with nickel-cadmium batteries, the self-discharge of nickel-hydrogen batteries is not large, but compared with the almost negligible self-discharge of lithium battery packs, nickel-hydrogen batteries are simply the king of discharge. 6. In the same volume, the lithium battery pack has a larger capacity than the nickel-hydrogen battery, so its call and standby time are longer than the nickel-hydrogen battery, and the price is higher than that of the nickel-hydrogen battery; and in general, the nickel-hydrogen battery cannot The convenience is greatly reduced by charging as you use it. Ni-MH batteries are the next generation of Ni-Cd rechargeable batteries. The energy ratio is higher than that of Ni-Cd. It has low voltage, slightly memory effect, certain pollution to the environment, moderate price, and battery life of about 1,000 times. Many of the surrounding nickel-metal hydride hybrid vehicles and electric models use nickel-metal hydride batteries.
