18650 rechargeable battery | Applications

The Application of 18650 rechargeable battery

The application of lithium secondary batteries in the energy battery industry benefits from its superior performance. With the continuous development of lithium battery technology, it has been widely used in our daily life; the repeated use of rechargeable batteries are more and more favored by consumers. Focus on the energy battery industry, fully understand the battery and then let us do “for our own use”. Currently 18650 lithium battery in the following fields have certain applications.

1. Energy Storage

Mainly used in base station power supply, clean energy energy storage, power grid power energy storage, battery backup for home, etc.

2. Automotive

Mainly refers to electric vehicles, electric bicycles, new energy vehicles, etc.

3. Digital

Mobile phone, tablet, laptop computer, electric toys, MP3/MP4, headphones, battery bank, model airplane, mobile power supply, etc.

18650 rechargeable battery Classification

18650 rechargeable battery production needs to have protective lines to prevent the battery from being overcharged and discharged. This, of course, is a necessary for lithium battery, this is also a common disadvantage of lithium battery, because the lithium battery adopts basic materials are lithium cobalt acid material, and lithium cobalt acid material lithium battery can not large current discharge, poor battery safety, from the point of classification, 18650 rechargeable battery can be classified through the following way.

1. Classification by Battery Utility

Power battery and Energy battery. Energy battery is characterized by high energy density, mainly used for high energy output. Power battery with high power density as the characteristics, mainly used for instant high power output, output battery. Power-energy lithium-ion batteries come along with the emergence of plug-in hybrid vehicles. It requires the battery to store high energy, which can support pure electric driving for a distance, and should also have good power characteristics to enter the hybrid mode at low power.

Simply understand, the energy type is similar to a marathon runner. To have endurance, it requires high capacity and does not require high current discharge performance;

Then the power type is a sprinter, who strives for explosive power, but also needs endurance,

2. Classification by Electrolyte Materials

Lithium-ion batteries are divided into liquid lithium-ion battery (LIB) and polymer lithium-ion battery (PLB).

Liquid lithium-ion batteries use liquid battery electrolytes (mostly for automotive batteries). Polymer lithium-ion batteries are replaced by solid polymer electrolytes, which can be “dry” or “gel”, and are mostly currently using polymer gel electrolytes. As for solid-state batteries, the electrode and electrolyte are strictly solid.

3. Classification by Product Appearance

Divided into: Cylinder, Pouch and Prismatic.

The cylinder and prismatic packaging are mostly steel or aluminum shells. The outer packaging of the pouch cells is aluminum-plastic film. In fact, pounch cell is also a square shape. In the market, it is customary to call the aluminum-plastic film packaged pouch cell, and some people call the soft pack battery a polymer battery.

For cylinder lithium-ion batteries, the model is usually 5-bit digits. The first two digits are the diameter of the battery, and the middle two digits are the height of the battery. Unit is mm. For example, the 18650 rechargeable battery is 18 mm in diameter and has a height of 65 mm in height.
