Understanding of the features of 18650 lithium batteries

Source: 2020 - 04 - 19 provinces hits: we are one of the most common in our daily life battery has two kinds: lithium ion battery and lithium iron phosphate battery. The former use 3. Charging 7 v voltage and maximum voltage cannot be more than 4. 2v。 The latter charge voltage of 3. 2 v, charge cut-off voltage of 3. 6v。 The two lithium batteries often appear in domestic 18650 lithium battery list. The characteristics of the lithium battery 1 18650. High voltage is the voltage is higher, not only can support 3. 6 v, can also support 3. 8 v and 4. 2 v, so compared with other battery will be much higher, we should know the nickel cadmium and nickel metal hydride batteries can only use 1. 2 v voltage. 2. Large capacity lithium battery capacity compared with other battery also had the very big enhancement, usually 1200 mah ~ 3600 mah, but if it is a common battery is only around 800 mah, if we use a combination of the lithium battery, then it will be higher, more than 5000 mah can easily. 3. Long service life of the battery life is very long. If we have been normal use, the service life of it is very high. Generally can reach more than 500 times, is more than twice the normal batteries. 4. High safety performance of lithium-ion batteries security in 18650 domestic lithium battery is very high on the list, there will be no explosion, burning, and very safe, non-toxic and pollution-free green. Can do the security in every aspects, under the high temperature performance is very good also, even under the high temperature of 65 degrees can achieve high emission efficiency. In order to prevent short circuit batteries, battery of the positive and negative are separated. So, basically do not appear short circuit. Also can be installed when using protection plate, which greatly avoid battery overcharge and over discharge, make the battery service life is longer. 5. No memory effect lithium battery no memory effect, so it is more convenient for daily use, mainly because if there is no memory effect, do not need to will the rest of the battery before charging. 8. Widely used lithium battery application range is very wide, not only can be used in notebook computers, walkie-talkie, portable DVD and other equipment, can also be used to model plane, toys, cameras and other products. 6. Low battery internal resistance of battery internal resistance is less than other liquid will be many domestic polymer battery internal resistance and even can do below 35 m Ω, so when the battery will not appear largely due to the power consumption, extend the standby time of mobile phone, from this perspective can meet international standards, so the lithium battery is a very good ideal choice. But 18650 lithium-ion battery production requirements, high demand is higher, compared with other batteries, the production conditions and the environment will be relatively high, to a certain extent, improve the cost, hope to get more high quality lithium batteries, the authors recommend is the best option to appear in the list of China in 18650 lithium batteries, lithium batteries, lithium batteries will be more quality assurance.
