1.5v Carbon battery.What are the advantages of lithium batteries?

　　1, the lithium battery voltage platform is high, the uniform voltage of the single battery is 3.7V or 3.2V, which is about equal to the series voltage of 3 nickel-cadmium batteries or nickel-metal hydride batteries, which is easy to form a battery power group. 2. Lithium batteries have a high energy density compared to batteries. With a high storage energy density, it has reached 460-600Wh/kg, which is about 6-7 times that of lead-acid batteries.

　　3. Compared with lead-acid batteries, lithium batteries are light in weight, and the weight is about 1/5-6 of lead-acid products under the same volume.

　　4, lithium battery service life is relatively long, the service life can reach more than 6 years, lithium iron phosphate as a positive battery with 1CDOD charge, there is a record of 1000 times. 5, with high power acceptance, during which the lithium ferrous phosphate lithium-ion battery used in electric vehicles can reach 15-30C charging and discharging ability, which is convenient for high-intensity acceleration.

　　6, low self-discharge rate, no memory effect, often used in daily electronic product power supply.

　　7, lithium battery up and down docility is strong, can be used in the environment of -20℃ -60℃, through the process of disposal, can be used in the environment of -45℃.

　　8, green environmental protection, regardless of consumption, use and scrap, does not contain, does not produce any lead, mercury, cadmium and other toxic and harmful heavy metal elements and substances.

　　What are the disadvantages of lithium batteries?

　　1, lithium batteries have poor safety, there is a risk of explosion.

　　2, lithium cobalt acid lithium batteries can not be large electric exile, poor safety.

　　3, lithium batteries need to maintain the line to prevent the battery from being overcharged and discharged.

　　4, high consumption requirements, high cost.

　　Lithium cobalt acid battery and ternary lithium battery comparison

　　1. Structure and cost

　　The positive electrode material of the lithium cobalt acid battery is lithium cobalt acid, the negative electrode material is graphite, the electrolyte is an organic solvent, and the positive and negative electrodes are separated by polyolefin film, and the battery capacity is high. The positive electrode material of the ternary lithium battery is nickel cobalt manganese oxide (NCM), the negative electrode material is also graphite, the electrolyte is an organic solvent, and the positive and negative electrode interval is also a polyolefin film. Compared with ternary lithium batteries, lithium cobalt acid batteries have a lower cost.

　　2. Energy density

　　Energy density is an important indicator of battery capacity, which determines the battery working time and charging frequency. Ternary lithium batteries have a high energy density, generally between 150-200 Wh/kg, while lithium cobalt acid batteries have an energy density between 100-120 Wh/kg. Therefore, under the same volume, the ternary lithium battery can provide a larger capacity of electricity.

　　3. Cycle life

　　Cycle life is the number of times a battery can be charged and discharged and continue to be used. Ternary lithium battery has a longer cycle life than lithium cobalt acid battery, under normal conditions of use, the cycle life of ternary lithium acid battery can reach more than 2000 times, and lithium cobalt acid battery is generally about 1000 times. This is because the ternary lithium battery uses a more stable positive electrode material, reducing the loss of the positive electrode material
