What are the characteristics of lithium batteries compared to other batteries?

Lithium battery characteristics analysis Lithium batteries are widely used in mobile phones, cameras, notebook computers, cordless phones, power tools, remote control or electric toys, cameras and other portable electronic devices. 1. Lithium batteries, rechargeable nickel-cadmium batteries, nickel-hydrogen batteries: The negative electrode of lithium batteries is graphite crystal, and the positive electrode is usually lithium dioxide. When charging, lithium ions move from the positive electrode to the negative electrode and are embedded in the graphite layer. During the discharge process, lithium ions detach from the outside of the negative electrode in the graphite crystal and move to the positive electrode. Therefore, during the charging and discharging process of the battery, lithium always appears in the form of lithium ions, rather than in the form of metallic lithium. This is why they are called lithium batteries, or lithium batteries. Lithium batteries have the advantages of small size, large capacity, light weight, no pollution, single-cell high voltage, low self-discharge rate, and many battery cycles, but they are more expensive. Nickel-cadmium batteries have small capacity, serious self-discharge, and serious environmental pollution, and they are being phased out. Ni-MH battery has high performance ratio and does not pollute the environment, but the single voltage is only 1.2v, so the application range is limited. two. Lithium battery characteristics 1. Higher weight-to-energy ratio and volume-to-energy ratio; 2. High voltage. The voltage of a single lithium battery is 3.6v, which is equal to the series voltage of three nickel-cadmium or nickel-metal hydride rechargeable batteries; 3. Self-discharge can be stored for a long time, which is the most prominent advantage of the battery; 4. There is no memory effect. Lithium batteries do not have the so-called memory effect of nickel-cadmium batteries, so do not discharge lithium batteries before charging; 5. Longevity. Under normal working conditions, the charge-discharge cycle of a lithium battery can reach more than 500 times. 6. It can be charged quickly. Lithium batteries can generally be charged at 0.5 to 1 times the current capacity, shortening the charging time to 1 to 2 hours; 7. Can be used in parallel at will; 8. Because the battery does not contain heavy metal elements such as cadmium, lead, mercury, etc., it has no environmental pollution , Is currently the most advanced green battery; 9. The cost is too high. Compared with other rechargeable batteries, lithium batteries are more expensive. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
