my country Energy Storage Network News: In recent years, electric vehicles are not just a concept, but are gradually entering people's lives. However, compared with the hot popularity of traditional fuel vehicles, electric vehicles are in stark contrast to the former. The crux of the problem is that battery life and cruising range are still a headache. However, technology is advancing and innovation is happening all the time. Recently, researchers announced a breakthrough in the stability of lithium-air batt

Li-ion battery wireless charging technology Wireless lithium-ion battery charging technology is a technology that uses magnets to charge devices without the use of wires at all. Wireless charging technology, derived from wireless power transmission technology, uses magnetic resonance to transmit charges in the air between the charger and the device, and coils and capacitors form resonance between the charger and the device to achieve efficient power transmission technology. Wireless charging is mainly divided

Precautions for UPS lithium-ion battery production process The production process of UPS lithium-ion batteries varies depending on different lithium-ion battery manufacturers, but because the principle is the same, the important production processes of lithium-ion batteries are basically the same, generally including: ingredients, coating, rolling, and cutting , Slitting, welding lugs, winding, packaging, baking, liquid injection, chemical formation, molding, volume detection and other processes.(Lithium - Ion B

Composition of lithium titanate battery Negative electrode: lithium titanate material Separator: Lithium-ion battery separator with carbon as negative electrode Electrolyte: lithium-ion battery electrolyte with carbon as negative electrode Battery shell: Lithium-ion battery shell with carbon as negative electrode Advantages and disadvantages of lithium titanate battery technology Lithium titanate battery has small size, light weight, high energy density, good sealing performance, no leakage, no me

Lithium-ion battery is a kind of secondary battery, which mainly relies on lithium ions to move between positive and negative electrodes to work. Lithium-ion batteries are composed of the following five parts: positive electrode material, negative electrode material, organic electrolyte, separator and battery case. Among them, the diaphragm is one of the key components of lithium-ion batteries, and has two crucial uses: 1. It serves as electronic insulation between the positive and negative electrodes: the separ

Lithium-ion batteries for electric vehicles have large capacity, many series and parallel cells, complex systems, high performance requirements such as safety, durability, and power, and are difficult to implement. Therefore, they have become a bottleneck affecting the popularization of electric vehicles. The safe working area of lithium-ion batteries is limited by the temperature and voltage windows. If the window is exceeded, the performance of the battery will decline rapidly, and even safety problems will occur

Solutions for active balancing and passive balancing of lithium-ion battery pack charging. The most important link we need to pay attention to when charging and discharging lithium-ion battery packs is the equalization link. Currently, there are two approaches to address the unbalanced condition of small Li-ion cells in a battery pack: active balancing and passive balancing. The equalization link is to ensure that the input and output of the lithium-ion battery pack are reasonable to each lithium-ion battery, so th

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
