\"Li-ion<\/figure>\n\n\n\n

Li-Ion batteries are mainly 9 types according to its battery chemistry. Among them the most used Li-ion batteries are LiCoO2, NMC, LiFePO4, NCA, and LiPo. Each battery type has a specific energy density, thermal stability, chemical structure, durability, and safety. Therefore, these are used for specific applications. <\/p>\n\n\n\n

The main 3 parts of the Li-ion batteries are anode, cathode and electrolyte medium. The anode and cathode are positive (+) and (-) terminals and the electrolyte medium is the filled battery chemistry material. The weight of the Li-ion battery is varied with the capacity, battery chemistry, and cell format and design. The most used 18650 cylindrical Li-ion cell weighs approximately 47 grams.<\/p>\n\n\n\n

The Li-ion battery capacity is the storage of ampers inside the battery. It is measured in Ah. The battery capacity depends on electrolyte material, cell size, and the number of cells in the pack of Li-ion battery. The energy density of the Li-ion battery is the energy stored in the unit volume of the battery. Energy density mainly depends on the battery chemistry material.<\/p>\n\n\n\n

The impedance of the Li-ion battery is the measurement of its resistance to the flow of electric current. Higher impedance can limit the battery’s effectiveness and reduce the overall lifespan. Lower impedance provides a higher discharge current when the Li-ion battery is used. <\/p>\n\n\n\n

The charging voltage and current for of the Li- ion battery are 4.2V and 0.52A for the 3.7V cylindrical cell. Charging time for the 3.7V\/cell Li-ion battery charge time is between 2-3 hours. Li-Ion batteries can be overcharged if it exceeds 4.2 V, and they can be overcharged if it is reduced to 2.5V.<\/p>\n\n\n\n

Li-ion batteries have main 5 voltage states. Those are nominal voltage of 3.7\/cell, charge cutoff voltage of 4.1-4.3V, end-of-discharge voltage of 2.5-3.0V, open circuit Voltage of 3.6-3.9V, and float voltage of 3.6-3.9V. These voltages are important while charging and discarding the li-ion battery. The standard discharge current of the Li-Ion 3.7\/cell battery is between 0.2C and 1C.<\/p>\n\n\n\n

The modern Li-ion battery memory effect is not considered. The self-discharge rate of Li-ion batteries is approximately 1.5-2% per month. But this can be varied with the temperature of the battery. Li-ion batteries can be used for approximately between 2-3 years or 300-500 charge cycles, whichever comes first. The cycle life of Li-Ion batteries is considered as 70-80% of the original capacity. The cycle life depends on battery material composition, charging, and operating conditions. <\/p>\n\n\n\n

Li-ion batteries should be used in the proper temperature. For the charging, use 0\u00b0C to 45\u00b0C. You can use it between -20\u00b0C to 60\u00b0C and it should store 15\u00b0C +\/- 5\u00b0C when it is not in use. Li-ion batteries can be damaged due to overcharging, deep discharging, heating, cooling, physical damages, incorrect storage, water, vapour, inappropriate chargers, and not used in a long time mainly. <\/p>\n\n\n\n

Due to the higher energy density, lower self-discharge, small size, no memory loss Li-Ion batteries are used in a wide range of applications such as small consumer products, vehicles and power sources mainly.<\/p>\n\n\n\n
