What is the difference between lithium batteries and ordinary batteries?
Lithium-manganese dioxide battery is a lithium-based anode to manganese dioxide cathode, and the use of organic electrolyte disposable batteries. The main features of the battery is the battery voltage is high, the rated voltage of 3V (2 times the normal alkaline battery); termination discharge voltage of 2V; than the energy (see above example); discharge voltage is stable and reliable; there is better Storage performance (storage time of 3 years), low self-discharge rate (annual self-discharge rate ≤ 2%); Operating temperature range -20 ℃ ~ +60 ℃.
Now the phone is very common, part of the phone is a nickel-metal hydride battery, but the smart phone is a lithium-ion battery. Proper use of lithium-ion battery to extend battery life is very important. Lithium-ion battery is currently the most widely used lithium battery, which according to the requirements of different electronic products can be made into a flat rectangular, cylindrical, rectangular and button, and there are several batteries in series with the battery pack. Lithium-ion battery is rated at 3.6V (some products 3.7V). The charge termination voltage at full charge is related to the battery anode material: 4.2 V for the anode material and 4.1 V for the anode material. The internal resistance of different anode materials are also different, slightly larger internal resistance of coke anode, the discharge curve is also slightly different. Commonly known as 4.1V lithium-ion battery and 4.2V lithium-ion battery. Most of the current use is 4.2V, lithium-ion battery termination discharge voltage of 2.5V ~ 2.75V (battery factory gives the operating voltage range or give the termination of discharge voltage, the parameters are slightly different). Lower than the termination of the discharge voltage to continue discharge known as over discharge, over discharge of the battery will have damage.
