Lithium iron phosphate battery is the best choice for inorganic building base station The base station without a computer room refers to the connection and transmission network between the base station's computer rooms. It is a macro station built by the outdoor integrat...

Generally speaking, if you want to choose lithium electric tools, in fact, one of the most concerned issues of most people should be lithium ion batteries, and most people would prefer to choose imported lithium ion batteries. The important reason is that this battery has a very obvious advant...

At present, the application range of lithium-ion battery is expanding, and its advantages are obvious. Among them, fast rechargeable lithium ion batteries have broad application prospects. At present, lithium-ion batteries have important applications in mobile phones, car chargers, fixed charg...

Effect of voltage uniformity on the series use of lithium ion batteries Abstract: The cycle life of 18650 single cell battery under different charging voltage and over-discharge current was tested. The SOC of battery pack is caused by the quantitative difference, and the inc...

Advantages and disadvantages of NiMH battery: Advantages of Ni-MH battery 1. High energy density, 1.5 times higher than nickel cadmium; 2. The battery voltage is 1.2v-1.3v, which is equivalent to nickel cadmium battery; 3. No...

In the use of lithium-ion batteries, it should be noted that the battery will enter the sleep state after being placed for a period of time. At this time, the capacity is lower than the normal value, and the service time will also be shortened. However, lithium-ion batteries are easy to activate. Th...

According to the internal structure of the power lithium battery, the lithium ion battery is composed of four parts: positive material, negative material, separator and electrolyte, while the lithium iron phosphate battery uses lithium iron phosphate as the positive material. The ternary lithi...

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...
