The 18650 lithium batteries of shallow advantage and use items

Source: 2020 - 04 - 19 21:09 hits: once it opens the understanding of lightning and electricity, since Benjamin Franklin to pursue the ancients think 'mysterious' things. Since then, many people have been thinking about how to store capture of power, so the battery has been gradually formed. In fact, one of the most important invention in the history of lithium batteries, deepened our understanding of electricity. 18650 lithium-ion batteries in the lithium battery service life is long, and a lithium-ion battery. In many areas, lithium battery can be seen, because the battery has a great advantage than other batteries. Obviously, the security is good, and it has been used in the large equipment, the following article will introduce knowledge of 18650 lithium batteries. The advantages of 18650 lithium batteries 1 18650 lithium batteries advantages. Higher security in comparison with other types of batteries, the battery will have a higher safety performance. In use, basically won't be an explosion or burn, and very environmental protection and safety, no toxic side effects. All kinds of safety performance of disposable, more than 500 times cycle, high temperature resistant. In order to prevent it short out, separate 18650 lithium battery of the positive and negative, so as to reduce the likelihood of the short circuit to the limit. Can be installed protective plate, avoid battery overcharge, over discharge, extend battery life. 2. Widely used in life, a lot of equipment will use lithium-ion batteries, the most common is that we can not live without mobile phones, computers. In addition, various types of audio equipment, aviation model, children's toys are made with lithium-ion batteries, as long as it is actually electronic equipment are basically can use the battery. 3 series, 18650 lithium-ion battery pack can assemble series or parallel. 4. Low internal resistance of the internal resistance of the polymer core is less than the liquid core internal resistance. Homebred the internal resistance of the polymer core can even less than 35 m, greatly reduces the battery power, to a large extent can phone standby time is longer, full compliance with international standards. Polymer lithium battery supports large discharge current, it is the ideal choice for the remote control mode, is the most promising alternatives to nimh batteries. 5. No empty battery before charging no memory effect, easy to use. 6. Batteries last longer than other types of lithium ion battery, the battery's working life is longer, in normal use case can charge and discharge more than 500 times, is more than twice the normal batteries. 7. Large capacity 18650 lithium battery capacity generally between 1200 and 3600 mah, the battery capacity is about 800 mah. If the 18650 pieces of 18650 pieces of lithium-ion batteries, lithium-ion battery pack synthesis 18650 pieces of more than 5000 mah lithium batteries can be easily. Use 18650 lithium battery is generally believed that if the no-load voltage of lithium-ion batteries is lower than 3. 0 v, it will run out of energy, so it is important to note that do not use less than 3. 2 v, otherwise it will shorten the battery life. When using 18650 lithium batteries, need to be aware of is the maximum voltage is 2 v battery. Usually, when we want to make sure that the battery voltage in 4. About 2 v. In the actual charging, pressure can be started from 3. 7 v up to 4. 2 v, of course, can not continue to rise, otherwise it will caused great damage to the battery.
