18650 cylindrical lithium battery is widely used in electric vehicles, electric bicycles/motorcycles, golf carts, solar power generation systems, mobile power stations, electric tools, communication base stations and other fields.

Electric Vehicles

At present, the battery of electric vehicles is mainly NiMH battery. As the manufacturing technology of NiMH battery is not yet mature, the market of NiMH battery in China is mainly occupied by Japanese and Korean enterprises, but with the continuous improvement of China’s technology in the field of new energy vehicles, it is believed that the market of NiMH battery in China will be expanded accordingly.

18650 cylindrical lithium battery as the core of electric vehicle power, it plays an important role in electric vehicles, the proportion of lithium-ion power batteries in electric vehicles is about 40% to 50%, of which 18650 cylindrical lithium battery occupies a large proportion.

18650 cylindrical lithium battery can be used as a backup or back-up power source in the power supply system of electric vehicles. Its energy density is low, but it can provide long time discharge. Therefore, it is one of the ideal backup power sources in the electric vehicle power system.

Electric bicycle/motorcycle

The advantages of 18650 cylindrical lithium battery are small size, light weight, high energy density and high safety performance, which can meet the requirements of electric bicycles and motorcycles. The market space of electric bicycle and motorcycle is very large, and the demand for 18650 cylindrical lithium battery is also very large.

After years of development, China’s electric bicycle industry has gradually formed a large production scale, and the demand for 18650 cylindrical lithium batteries is also increasing. In 2018, the total production of electric bicycles in China was 36.339 million units, an increase of 5.3% year-on-year, of which the production of 18650 cylindrical lithium batteries was 2.152 million units, an increase of 35.3% year-on-year.

It is understood that in 2019, after the official implementation of the “new national standard for electric bicycles” policy, domestic electric bicycle manufacturers must obtain 3C certification to carry out production. Due to the widespread use of 18650 cylindrical lithium batteries in electric bicycles, this part of the market is being rapidly filled, and the demand for 18650 cylindrical lithium batteries in China’s electric bicycle industry is expected to reach 2.4 million units in 2019.

Golf Carts

18650 cylindrical lithium battery is the main source of power for golf carts, because the golf carts are used in outdoor environment and need to travel a distance of more than 50 km per day, so they need to have certain requirements in terms of range and power. 18650 cylindrical lithium battery is small in size and light in weight, which is its main feature, and 18650 cylindrical lithium battery is packed in aluminum case, which can effectively reduce the weight of the battery pack. 18650 cylindrical lithium battery has the characteristics of high voltage and high energy density, its own voltage can reach about 3.6V and energy density is about 170 Wh/kg, which can provide enough power for golf carts.

The application of 18650 cylindrical lithium battery in the field of golf carts mainly includes: electric golf cart power supply system, electric golf cart mobile power system source system, etc. 18650 cylindrical lithium battery will be more and more widely used in the future application scenario due to its own characteristics and advantages.

Solar power generation system

Solar power generation system is a device that converts solar energy into electrical energy, generally consisting of solar panels, controllers and batteries, etc. On the solar panel side, its output DC power will be converted into AC power, which will then be converted into stable DC power by the inverter to supply power to the load. On the controller side, it is mainly to control the battery charging and discharging to ensure a stable output of electricity.

18650 cylindrical lithium battery has high energy density, small size, light weight, long cycle life, stable working voltage, etc. Therefore, 18650 cylindrical lithium battery applied in solar power system has greater advantages. Compared with ordinary lithium batteries, 18650 cylindrical lithium batteries used in solar power generation systems can improve the reliability and stability of power generation systems, reduce the cost of solar power generation systems, and provide greater power and longer service life. For example, when 18650 cylindrical lithium batteries are used in solar power generation systems, a variety of operating voltages and output power levels can be designed to meet different needs.

Mobile Power Station

Mobile power station is a kind of power supply system that integrates power generation, energy storage and power supply. It is mainly used to supply power to mobile equipment, such as motorcycles, electric vehicles, etc. Since this power supply system is highly mobile and can operate under field conditions, it can provide power to mobile equipment when needed, so its application is very wide. Mobile power station batteries mainly include 18650 cylindrical lithium battery and 21700 cylindrical lithium battery. 18650 cylindrical lithium battery has the characteristics of light weight and small size, which is easy to install and transport. 21700 cylindrical lithium battery is a new type of polymer lithium ion battery, which has the advantages of high multiplier discharge capacity and high energy density to meet the requirements of power. 18650 cylindrical Li-ion battery can be used with power car to form a power mobile power station.

Power tools

18650 cylindrical lithium battery can be used for power supply of power tools, generally according to the type of battery used to choose the corresponding model. 18650 cylindrical lithium battery can work in all kinds of use environment of power tools, such as electric screwdriver, electric screwdriver, electric vacuum cleaner, etc. Because 18650 cylindrical lithium battery has higher energy density, its application range is wider than that of soft pack battery.

With the development of economy, the communication business is also developing rapidly, and the performance requirements of communication base station equipment, as the core component in communication base station, are getting higher and higher. As one of the important components in the base station, the quality of the battery directly affects the quality of the whole communication base station. For a long time, communication backup power mainly uses lead-acid batteries, but lead-acid batteries have short service life, frequent daily maintenance, and are not friendly to the environment and other shortcomings. The 5G communication base station has high energy consumption and a trend of miniaturization and lightness, which requires energy storage system with higher energy density. Therefore, choosing a high-quality, safe and reliable battery is very important to improve the operating efficiency and work stability of base station equipment. Lithium-ion batteries are very suitable for use in high-power communication base station equipment because of their high operating voltage (generally around 3.7V) and high current (current generally up to 30A or more).
