The principle of rechargeable 18650 battery

1. Charging: The charging process of the 18650 battery is carried out by a lithium battery charger. The charger converts the AC power to DC and sends it through the positive terminal of the battery to the inside of the battery. During charging, lithium ions migrate from the positive electrode to the negative electrode, forming an electric current.
2. Discharging: When an electronic device needs to use the energy of the battery, the 18650 battery will generate current through the migration of lithium ions inside. During this process, lithium ions migrate from the negative electrode to the positive electrode, creating an electrical current that powers electronic devices.

Features of rechargeable 18650 battery

1. Environmental protection: 18650 battery, as a rechargeable battery type, has many environmental protection features. First, they can reduce their dependence on traditional energy sources and reduce carbon emissions by using renewable energy sources for charging, such as solar and wind power. In addition, 18650 batteries have a lower risk of environmental contamination than conventional NiMH and NiCd batteries because they do not contain heavy metal elements commonly found in these batteries.

2. High energy density: The 18650 battery has high energy density, which means it can still store a large amount of electricity in a small size. This makes it of high practical value in portable electronic devices. For example, an 18650 battery can have a capacity of 3000-4000mAh, which can provide about 8-12 hours of battery life for a smartphone.

3. Long life: The life of rechargeable 18650 battery can generally reach more than 500-1000 charge and discharge cycles, and with reasonable use and maintenance, the life can be further extended. This greatly reduces the use cost of electric tools and portable devices, and is also conducive to resource recycling and environmental protection.

4. High safety: 18650 lithium-ion batteries pay attention to safety performance in the design and production process. Lithium-ion batteries have low internal resistance and can withstand large currents during charging and discharging. In addition, lithium-ion batteries also have overcharge protection and overdischarge protection functions, which can automatically cut off the current when the battery is fully charged or exhausted to protect the battery from damage.

5. Rechargeable design: The 18650 battery is a rechargeable battery, which means it can be recharged by a charger after the battery is exhausted, and can be used again. This greatly improves the utilization rate of the battery and reduces the cost of use. At the same time, the internal resistance of the 18650 battery is small, so its charging efficiency is high, and it generally only takes 30-60 minutes to fully charge, which meets the needs of users.

6. Wide range of applications: rechargeable 18650 battery are not only widely used in the field of electric tools, but also show strong competitiveness in the field of portable devices. For example, portable power supplies, charging treasures and other devices can use 18650 batteries. Its small size, high energy density, and long lifetime make it a great advantage in these fields.
