With the rapid development of the mobile electronic equipment and electric vehicle market, 18650 lithium battery has attracted much attention as an important power energy source. This article will introduce the specifications and parameters of 18650 lithium batteries, and conduct a detailed analysis from basic parameters to application scenarios to help readers better understand this important energy storage device.

Basic parameters

The 18650 lithium battery is a cylindrical lithium-ion battery, and the "18650" in its name represents its size specification, with a diameter of 18mm and a height of 65mm. This standard size makes 18650 lithium batteries widely used in a variety of devices, including portable electronic devices, power tools, electric vehicles, etc. In addition, the nominal voltage of 18650 lithium batteries is generally 3.7V, the charge cut-off voltage is 4.2V, and the discharge cut-off voltage is 2.75V. These basic parameters provide an important reference for the design and application of 18650 lithium batteries.

Capacity and energy density

The capacity of 18650 lithium batteries is an important indicator to measure its stored electrical energy, and the commonly used unit of capacity is milliampere-hour (mAh) or ampere-hour (Ah). Generally speaking, the capacity of 18650 lithium battery is between 1000mAh and 3500mAh, and batteries of different capacities are suitable for different devices and scenarios, meeting the diverse needs in the market. In addition, energy density is also an important parameter to evaluate the performance of lithium batteries, the energy density of 18650 lithium batteries is usually between 150-250Wh/kg, high energy density means higher performance and lighter equipment.

Charge-discharge characteristics

The charge-discharge characteristics of 18650 lithium batteries play a crucial role in their performance in practical applications. The charge rate and discharge rate are important indicators to evaluate the performance of the battery, which is usually expressed as the C value. The charging rate refers to the ratio of the maximum allowable charging current of the battery to its capacity, and the discharge rate refers to the ratio of the maximum allowable discharge current of the battery to its capacity. In addition, cycle life is also an important indicator to evaluate the quality of the battery, usually expressed in the number of charge and discharge cycles, high cycle life means that the battery has a longer service life
