What is the 18650 lithium-ion battery capacity? Lithium-ion battery capacity calculates? 18650 lithium-ion battery as the most widely used lithium-ion battery species, 18650 lithium-ion battery capacity is an important selling point of manufacturers, in addition, the same capacity 18650 lithium-ion battery cell brand also affects prices Factors, 18650 lithium-ion battery capacity is distributed between 1000 mAh to 3000mAh, but technology is more mature between 1800 mAh to 2600 mAh. What is the 18650 lithium-ion battery capacity? 18650 The capacity of lithium-ion batteries can do how much milliamp, or a matter of great discussion, there is always a concern of many from the industry, in the past few years, my country's various lithium-ion battery manufacturers have improved, constantly Experimental research and development, the capacity is also increased. Common 18650 batteries are divided into lithium ion batteries, lithium iron phosphate ion batteries.
The lithium-ion battery voltage is a nominal voltage of 3.7V, the charging cutoff voltage is 4.2V, the lithium phosphate ion battery nominal voltage is 3.
2V, the discharge cutoff voltage is 3.6V, the capacity is usually 1200mAh-3350mAh, the common capacity is 2200mAh- 2600mAh. If a capacity 2000MAH power-type 18650 lithium-ion battery is only 1000mAh5, a normal capacity 18650 lithium-ion battery is up to 4.
2V, and the maximum power 18650 lithium ion battery is about 3.65V. The normal capacity 18650 lithium-ion battery nominal voltage is 3.
7V, the power 18650 lithium ion battery nominal voltage is 3.2V. In real life, the 18650 lithium-ion battery can do 3500mAh, but there is no batch market without selling.
At present, there are 2950mAh sold in the market. This capacity battery is called 3000mAh, and this capacity is basically imported. Various 18650 lithium-ion batteries Voltage and capacity specifications: 18650 nickel-hydrogen battery voltage is 1.
2V, common capacity is 2500mAh18650 lithium ion battery voltage is 3.6V, the common capacity is 1500mAh-3100mAh18650 lithium ion battery capacity, the more Long, you can supply a longer-time power supply for users, but under the same system, 18650 lithium-ion battery capacity will bring highly negative use, so capacity and price balance are very important. Lithium ion battery capacity calculation? Calculation method of lithium ion battery capacity (C): Capacity C = discharge battery (constant current) i ¡Á discharge time (hour) T reverse: Discharge time t = capacity C / discharge current (constant current) I, if the nominal voltage (V) and nominal capacity (AH) of the battery can be calculated by calculating the value of the rated energy, the formula is: wh = vxah, such as a 12V20AH lithium ion battery, the rated energy is 12 ¡Á 20 = 240; In general, nominal voltage and nominal capacity are marked on the battery.
Summary: The capacity of the 18650 lithium-ion battery is related to the size of the model, depending on the thickness, width and length of the battery. In addition, it is also related to the material and size of the battery. The actual calculation formula of lithium-ion battery capacity is complicated, and the volume is not linear relationship.
To take into account many factors, such as materials, the actual capacity is much large, the larger size, and the larger capacity / volume ratio is als.
