리튬폴리머전지와 일반 리튬이온전지의 차이점. Posted by batterymanufactory.com
1. General lithium ion battery The general lithium-ion battery is commonly known as "lithium battery", which is currently a battery system with relatively good overall performance. The negative electrode of a lithium-ion battery is a carbon material, such as graphite. The positive electrode is a transition metal oxide containing lithium, such as LiMn2O4. (1) Advantages of lithium ion batteries: ①The working voltage is high. The working voltage of lithium-ion battery is 3.6V, which is three times that of nickel-cadmium and nickel-hydrogen batteries. ②The specific energy is high. The specific energy of lithium-ion batteries has reached 140Wh/kg, which is 3 times that of nickel-cadmium batteries and 1.5 times that of nickel-hydrogen batteries. ③Long cycle life. At present, the cycle life of lithium-ion batteries has reached more than 1,000 times, and can reach tens of thousands of times under low-depth discharge, which exceeds that of other secondary batteries. ④S...
