Due to the inherent characteristics of the materials, wet process membranes and dry process membranes have their own advantages and disadvantages:Wet membrane is lightweight and not easy to tear, but the melting point of PE is 135 ℃, which is lower in safety than dry membrane. In addition, due to d...

1: Lithium battery type and capacity selection.Firstly, the continuous current that the battery needs to provide should be calculated based on its own motor power (actual power is required, and the riding speed usually corresponds to a corresponding actual power). For example, if the motor has a con...

Lithium batteries labeled as 3.7V or 4.2V are one thing. It's just that the manufacturer's labeling is different. 3.7V refers to the platform voltage at which the battery is discharged during use, while 4.2V refers to the voltage at full charge. The common rechargeable 18650 lithium batterie...

What does the amount of C behind the battery mean?Represents the discharge capacity of the battery, which is the most important difference between ordinary lithium-ion batteries and power lithium-ion batteries. Power lithium-ion batteries require a large current discharge. The discharge capacity of...

The first step is to open the four corner screws of the battery and carefully open the upper cover. It can be seen that there are four 12V lead-acid batteries inside.The second step is to remember the battery circuit clearly, and then use an electric soldering iron to remove the wires from the batte...

The characteristics of fuel cell engines1. The advantages of fuel cells1) Energy saving, high conversion efficiency, and no need for petroleum fuelsa) Except for producing hydrogen gas through gasoline reforming, other fuels (such as methanol and hydrocarbons) generally do not use petroleum fuels.Th...

1. Freezing method for repairing bulges in aviation model polymer lithium-ion batteries: Wrap your aviation model lithium-ion battery in a dry towel, then wrap it in newspaper on the outermost layer, and put it in the refrigerator for 12 hours. After that, take it out. The battery shape will be rest...

K-value of lithium-ion batteriesThe K value refers to the voltage drop of a battery per unit time, usually expressed in mV/d, used to measure the self discharge rate of lithium-ion batteries.The commonly used K value measurement methods are as follows:Measure OCV1 at time t1Measure OCV2 at t2K is eq...

The report on the development and prospects of China's lithium-ion battery cathode material market during the 13th Five Year Plan (2017 version) released by Car Research Consulting analyzed a total of 200 lithium-ion battery cathode material companies, including 39 listed companies in Shenzhen,...

oneWhat is an A-grade battery cell?A-grade battery cells are usually ordered directly by the factory using the battery cells to the battery cell factory. The battery cell factory arranges production based on its own production capacity and technical capabilities, and through a series of battery cell...
