Use a pen to power the power supply or power supply from the DC/DC boost circuit Add a starting circuit based on the original DC/DC Portable products generally use battery power supply, and because of the consideration of cost and volume, there is a tendency to reduce the number of batteries and volume in design. If the number of batteries is reduced, it will cause the power supply voltage to be lower than the working voltage required by the equipment. At this time, the DC/DC boost circuit is used. In additio

In terms of positive material materials, domestic companies are in the upperisement, both technology and scale, and future development prospects are expected; in terms of negative electrode materials, domestic companies have a comprehensive leading advantage. The electrolyte is controlled by foreign companies because of patents and core additives, and the formula is subject to the client. Domestic electrolyte manufacturers have actually become substitutes. In terms of diaphragm, domestic companies have made thei

The performance of lithium -ion battery positive materials directly affects the performance of lithium -ion batteries, and its cost also directly determines the cost of battery costs. There are many industrialized production processes in the positive electrode materials, and the synthesis routes are relatively complicated, and the control of temperature, environment, and impurities is also strict. There are many industrialized production processes in the positive electrode materials, and the synthetic routes are re

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
