Important method of pre -lithium 1. The negative electrode advancement method Let the negative electrode become separate into it, and then assemble it with the positive pole after the negative electrode is formed to prevent the loss of the positive lithium ion and greatly improve the first efficiency and capacity of the battery. The advantage of this pre -lithium method is that it can simulate the normalization of normalization into the process, while ensuring that the formation of the SEI membrane is similar

For the protection of the use of power lithium -ion battery packs, some measures are currently taken in battery product design and application control. According to the analysis of battery resistance, the stronger the resistance of the battery positive material is stronger, the stronger the corresponding battery resistance. Therefore, in order to improve the overcoming performance of lithium -ion batteries, on the one hand, in battery products, in battery products During the design process, safety devices such as P

Lithium-ion battery protection board equalization principle Commonly used equalization charging technologies include constant shunt resistance equalization charging, on-off shunt resistance equalization charging, average battery voltage equalization charging, switched capacitor equalization charging, step-down converter equalization charging, inductance equalization charging, etc. When a group of lithium-ion batteries are charged in series, each battery should be charged in a balanced manner, otherwise the performa

The general process of coating: the coated substrate is released from the unwinding device and fed into the coating machine. After the end of the substrate is connected into a continuous belt by the splicing table, it is sent to the tension adjustment device and the automatic deviation correction device by the pulling device, and enters the coating device after adjusting the tension and position of the film path. The electrode sheet slurry is coated in sections according to the predetermined coating amount and blan

1. Application scenarios of large-scale energy storage systems New energy power plants, wind power or solar power plants, in order to achieve the purpose of stabilizing output power fluctuations, more and more power plants are beginning to be equipped with energy storage systems. Independent energy storage power stations, with the reform of the power system gradually entering people's field of vision, independent energy storage power stations that make a living by reselling electricity have gradually emer

The principle of charge and discharge of lithium -ion batteries. To understand the mystery of the fast charging of lithium -ion batteries, we must first know the charging and discharge principle of lithium ion battery. The battery has a bipolar: the positive electrode is a lithium compound with a negative extremely graphite. Charging and discharge are the mutual conversion of electrical energy and chemical energy. During the lithium ion, it is also turning into different compounds during the positive and n

What is a wireless charger The wireless charger refers to the charger on the terminal device that needs to be charged without the traditional charging power cord. The latest wireless charging technology is used. By using the magnetic field generated between the coils, the magical transmission electrical energy, the inductive coupling technology will be Become a bridge connecting the charging base station and equipment. What is the material of the wireless charger? Wireless charger characteristics 1. In

In the era of smart phones, we have witnessed the processor from single -core, dual -core to quad -core and eight cores, and now it is not surprised to get out of ten cores. ; The size of the screen is the same, and the 4 -inch and 5 -inch are now more than 6 inches or more. What is fast charge technology? How to achieve fast charging? But the only regret is that the technological innovation of mobile phone batteries is still slow, the battery life is not enough to meet the daily use of users, and it is still

Science and technology development speed Quick charging is an increasingly popular function that allows you to only need a small part of the time to complete the work of charging mobile phones. But not all the calls use the same type of fast charging-not all chargers support various standards. Understand fast charging The output of the charge is measured by ampere digital and voltage. The current is the power from the battery flow to the connection device, while the voltage is the strength of the cur
