About mobile phone maker, on the application of lithium-ion batteries

Source: 2020 - 03 - 28 then hits: the use of mobile phone manufacturers of lithium batteries although in recent years, almost all the manufacturers tend to use lithium ion battery, but the world's major mobile phone manufacturers choose battery or have their own characteristics and habits, such as: once in the same historical period nokia: Ni - MH ( nimh) Batteries, free ( Liquid lithium ion battery, instead of using the lip ( Polymer lithium ion batteries. Ericsson: nickel metal hydride batteries, lithium batteries, lithium batteries. MOTOROLA: nickel metal hydride batteries, lithium batteries, not lithium battery. When Ericsson in the mobile phone use lithium ion, lithium battery for the first time, it is not hard to see that it is the pioneer of mobile technology. According to the data, I found the main producers of polymer lithium ion battery is Japan's SONY, panasonic, GS, etc. In 2000, the production of 21 million units, 50% for Ericsson mobile phone. In 2002, the lithium ion battery in other mobile phone manufacturers has been widely used and promoted. However, the use of polymer lithium ion battery is still far from the level of all mobile phone maker, products widely used. On the other hand, the lithium ion battery has many advantages, but there are also disadvantages, such as high price, fewer charge and discharge. Lithium battery charge and discharge times only is 400 - 600 times, especially improved products is only 800 times. But nimh batteries charging times can reach more than 700 times and part quality product cycle count up to 1200 times. Therefore, nickel metal hydride batteries than lithium battery has a longer service life. In addition, at much cheaper than lithium battery. Moreover, strictly speaking, lithium battery memory effect, but its memory effect is very low, almost negligible. So far, there has been no perfect battery.
