Use of lithium batteries by mobile phone manufacturers

　　Although almost all manufacturers have tended to use lithium-ion batteries in recent years, the choice of batteries by the world's major mobile phone manufacturers still has its own characteristics and habits, such as once in the same historical period:

　　Nokia: Ni-MH (nickel-metal hydride) battery, LiB (liquid lithium ion) battery, not LiP (polymer lithium ion) battery. 6 e4 K1 q( [+ W8 J6 m- s3 V

　　Ericsson: Ni-MH battery, LiB battery, LiP battery.

　　MOTOROLA: Ni-MH battery, LiB battery, not LiP battery.

　　It is not difficult to find that from the first use of LiP polymer lithium-ion batteries for mobile phones, Ericsson reflects its own mobile phone technology pioneer. According to the information I found, the main manufacturers of polymer lithium-ion batteries are SONY, Panasonic, GS and other companies, and the production volume in 2000 reached 21 million, of which 50% is Ericsson mobile phone supporting. Today, in 2002, lithium-ion batteries have also been widely used and popularized in mobile phones of other mobile phone manufacturers. However, the use of polymer lithium-ion batteries is far from being popularized in all mobile phone manufacturers' products, and it will take some time for them to be widely used.

　　On the other hand, although lithium-ion batteries have many advantages, they also have drawbacks, such as high price and low charge and discharge times. The charge and discharge times of lithium batteries are only 400-600 times, and the specially improved products are only 800 times. The number of charging times of nickel-metal hydride batteries can reach more than 700 times, and some good quality products can be charged and discharged up to 1200 times, so as to compare, nickel-metal hydride batteries are longer than lithium batteries. In addition, the price of nickel-metal hydride batteries is also much lower than lithium batteries. And strictly speaking, lithium batteries will also have a memory effect, but its memory effect is very low, basically negligible.
