5 major differences between nickel-metal hydride batteries and lithium-ion batteries

1. The difference in size. Relatively speaking, the volume of lithium-ion batteries is larger than that of nickel-hydrogen batteries, but this is relatively speaking, because the capacity of lithium-ion batteries of the same volume is higher than that of nickel-hydrogen batteries, so lithium Ion batteries are relatively small in size, lighter in weight, and easy to carry, so they are very suitable for various new mobile devices, such as mobile phones, computers, PDAs, and so on. Lithium-ion batteries have no memory effect, so they can be charged as you use them. However, charging too much will reduce the battery life. You can use them for a while and recharge them. Ni-MH batteries have a low memory effect. Generally, it is best to recharge the battery after the battery is consumed. However, if it is urgent, you can directly charge it without waiting for the electricity in it to be discharged. In addition, the self-discharge rate of lithium-ion batteries is very low, so the stored power in the battery can be maintained for a long time. Second, the amount of power Ni-MH battery and lithium-ion battery have many differences, and the amount of power stored is one aspect. Buyers generally care about battery power. Compared with nickel-metal hydride batteries, lithium-ion batteries have a higher specific energy, that is, the battery contains more power than nickel-metal hydride batteries under the same volume, so it is like the automatic phone we use. The battery is usually a lithium-ion battery, which is light in weight and small in size, and can also meet certain electrical capacity requirements. 3. Self-discharge effect As the name implies, self-discharge is the power consumption of the battery when not in use, that is, the ability of the battery to maintain power. The greater the self-discharge effect, the shorter the battery's service life. If the battery has a self-discharge rate due to a series of reasons If it is too large, its service life may be directly shortened. There is a difference in the self-discharge rate of lithium-ion batteries and nickel-metal hydride batteries. Although their self-discharge effects are not large, the self-discharge of the latter is widespread. Because the natural materials used are different, lithium-ion batteries have a great advantage in maintaining power. If nickel-hydrogen batteries are considered to have low self-discharge, then the self-discharge of lithium-ion batteries can be directly ignored. To some extent, lithium-ion batteries can be regarded as a new battery that is better than nickel-hydrogen batteries, and can be used as a better product to replace nickel-hydrogen batteries. Fourth, the size of nickel-metal hydride battery market is obviously longer to use nickel-metal hydride batteries than lithium-ion batteries, so nickel-metal hydride batteries have so far been available in a variety of specifications for customers to choose from, just like the special-shaped nickel-metal hydride batteries that you often hear. It is Ni-MH batteries of different specifications and models. However, because the application field of lithium-ion batteries is more specific, the specifications and sizes of their production are also more specific. 5. The application fields are also different. With the popularity of computers and mobile phones, the demand for mobile phone batteries in the market is increasing. In particular, the consumption of mobile phone lithium-ion batteries is the largest. In addition to the digital electronics industry, lithium-ion Batteries are also widely used in new energy vehicles, communication base stations and other places. Ni-MH batteries are generally used in electrical equipment, lamps, and electronic toy industries. The difference between nickel-metal hydride batteries and lithium-ion batteries is probably the same. When making a selection, you must follow your actual needs, so that you can choose a suitable battery. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
