Lightness The traditional lead-acid battery is relatively large in volume, and the vehicle weight is relatively heavier. The lithium-ion battery is not only small in size, but also relatively light in weight. Therefore, lithium-ion battery has more advantages in lightness th...

Difference between dry method and wet method of lithium-ion battery separator Comparison between wet diaphragm and dry diaphragm of lithium ion battery. Diaphragm is the core of lithium ion battery preparation. Lithium ion battery diaphragm is generally divided into dry proc...

The internal resistance of lithium-ion batteries is very high because the electrolyte inside is colloid rather than aqueous solution. In addition, the electrode material with extremely low water content and stable physical and chemical properties also enables the lithium ion battery to work safely i...

The protection board is designed to ensure safety and ensure that the lithium-ion battery will not be overcharged or over-discharged. In the past, overcharge and over-discharge of lithium-ion batteries would cause battery damage or explosion, fire and other hazards, so there was also a protect...

The 18650 lithium-ion battery is screened before the PACK. Different customers have completely different requirements for the cells before the 18650 lithium-ion battery PACK. Because the 18650 lithium-ion power battery is highly automated, stable and replaceable, it can effectively reduce production...

Recently, Jianyu Huang of Sandia National Laboratory in the United States and his research team announced that they had successfully developed the world's smallest nanolithium-ion battery. The rechargeable lithium-ion battery was made under a projection electron microscope of the Center fo...

1. Get into the habit of charging more every day. Although the battery can be used for several hours, or even longer, it is still necessary to form the habit of charging every day, so that the battery is in a shallow cycle state, which is good for extending the service life of the battery....

(1) Very high barrier The transmittance of water vapor shall be less than 1× 10-4~1× 10– 6g/m2 d1atm； The oxygen transmittance shall be less than 1× 10-1~1× 10-3g/m2 d1atm； This requirement is about 10000 times higher than that of...

Battery activation is called power scale calibration on Lenovo power management software. When Everest is used to test the power supply on the PC side, there is a design capacity, followed by the full charging capacity. If the two values are the same, Then you will see that the battery loss it...

18650 battery life theory is 1000 cycles of charging. Because of the large capacity of unit density, it is often used for notebook batteries. In addition, because of the excellent stability of the 18650 in operation, the 18650 lithium-ion battery is made up of three components at the same time...
