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...

There are two kinds of packaging methods for flexible lithium-ion batteries: molding packaging and non-molding packaging. Formed packaging refers to box packaging. This packaging method first punches the packaging material into a box shape. The depth of the box depends on the battery. Because...

1. Overcharge explosion The charging voltage is greater than 5V due to the loss of control of the protection circuit or the detection cabinet, resulting in the decomposition of the electrolyte, the violent reaction inside the battery, the rapid rise of the internal pressure...

The measurement units of lithium-ion batteries are working voltage (V), milliampere-hour (mAh), and watt-hour (Wh), which is commonly used on laptop batteries. When we compare the battery capacity, we usually use milliampere hour (mAh) as the unit of comparison. For example, the rechargeable b...
