AAA rechargeable battery

　　Advantages and disadvantages of lithium batteries:

　　1. Advantages

　　1. Low-carbon environmental protection, whether manufacturing, application or destruction, does not contain or will not contain all harmful heavy metal elements and lead, mercury, cadmium and other chemicals.

　　2. Lithium ions have a long service life. The battery has been using positive grade lithium iron phosphate batteries for over six years. The rechargeable battery with the positive electrode is charged and discharged using 1 disc with 1000 application records.

　　3. Lithium high-voltage service platform: The average voltage of a single rechargeable battery is equal to or equal to the series voltage of three nickel-cadmium or nickel-metal hydride rechargeable batteries.

　　4. The charging capacity of lithium phosphate battery for pure electric vehicles is 1530c, which is conducive to high toughness starting and acceleration.

　　Lithium has a higher specific energy. The relative density of high energy storage technology is 460 to 600wh/kg, which is 6 to 7 times that of lead-acid batteries.

　　6. The net weight of lithium-ion batteries is lighter than that of lead-acid batteries. The net weight of lithium-ion batteries is about 1/5 or 6 of the same volume.

　　7. AAA rechargeable battery has a short life and no recall effect;

　　8. Lithium batteries have strong adaptability to high temperatures and ultra-low temperatures. It can be used in -2060c environment and can be used in -45c environment after processing.

　　2. Disadvantages

　　1. Lithium-cobalt data cannot be charged and discharged under high current, and the safety factor is poor.

　　2. The safety factor of lithium-ion batteries is poor and there is a danger of explosion.

　　3. High production and manufacturing regulations and increased costs.

　　4. All lithium-ion appliances must maintain a power circuit to prevent excessive charging and discharging.
