　　Factors affecting the service life of ternary 18650 battery 3.7v 1800mah

　　Regarding the factors that affect the service life of ternary 18650 battery 3.7v 1800mah, Hydrogen Cloud Chain believes that this must be analyzed from two aspects: the structure and use conditions of the rechargeable battery itself, such as: lithium battery materials, use environment and optimal operating conditions, etc.

　　Specifically, during the use process, due to improper use, irreversible electrochemical corrosion occurs inside the lithium battery, resulting in volume reduction, such as the dissolution of the lithium battery electrolyte inside the battery, and the specific loss of active substances inside the battery. , these will immediately cause the service life of the ternary lithium battery to be sharply reduced.

　　Of course, when the lithium battery of a pure electric vehicle reaches the end of its service life, it does not mean that the battery cannot be charged or discharged. It just means that the charge and discharge capacity of the battery at this time is lower than that of a new battery. If Repeated use will bring a worse driving experience to users. Since the service life specifications of power 18650 battery 3.7v 1800mah were formulated two years ago, at that time, the battery power was not large, the cruising range of electric vehicles was short, and the attenuation coefficient was less than 80% of that of new rechargeable batteries. It does feel that the mileage has been reduced a lot. For example, if the mileage is originally 200 kilometers, the attenuation coefficient of the rechargeable battery reaches 80%, and the battery needs to be recharged after driving for 160 kilometers. Nowadays, the cruising range of electric vehicles is already very high, and users with an attenuation factor of 20% no longer feel so strongly about battery vehicles.

　　Application prospects of ternary 18650 battery 3.7v 1800mah

　　Data show that by 2020, the use of ternary 18650 battery 3.7v 1800mah will increase by 8%. The cars we generally use use ternary 18650 battery 3.7v 1800mah, and their use share has grown rapidly, reaching close to 6% four years ago. 10. The share of special-purpose vehicles is higher than that of new energy buses. Nowadays, all popular car series such as BAIC and BMW 5 Series use ternary 18650 battery 3.7v 1800mah, so ternary 18650 battery 3.7v 1800mah are widely used in various electric vehicles.

　　Based on the above discussion, we know that compared with the past two years, the performance of ternary 18650 battery 3.7v 1800mah has been greatly improved. Compared with ordinary lithium cobalt oxide batteries, its rated current and capacity have far exceeded them. Although the manufacturing cost of ternary 18650 battery 3.7v 1800mah is relatively high, their volumetric density and circulation characteristics are very high, so their service life is relatively long. In addition, ternary 18650 battery 3.7v 1800mah have been widely used in various passenger vehicles and special vehicles, so ternary 18650 battery 3.7v 1800mah can be considered the leader in rechargeable batteries.
