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

Three technologies to improve the voltage performance of cathode materials for lithium-ion batteries Increasing the voltage of the positive electrode data of lithium-ion batteries is a new idea to improve the energy density of lithium-ion batteries in recent years. The high-voltage data include two kinds of cathode data: spinel-like crystal structure and olivine-like crystal structure. LiMPO4(M=Co,Ni) is a typical high-pressure olivine crystal structure. Among them, the discharge potential of LiCoPO4 is 4.8v, th

Li-ion battery opportunities and challenges Opportunity 1: Low-carbon and environmental protection, the global wave of vehicle electrification is irreversible Driven by factors such as low-carbon environmental protection, power safety, and industrial support, the global electric vehicle market has developed rapidly. As of the end of 2017, the market share exceeded 3.4 million vehicles, with a market share exceeding 1%, and the annual compound addition rate reached 58%. The electrification trend of automobiles

Lithium-ion battery packs are generally composed of multiple batteries connected in series, but if the capacity of the batteries does not match, the capacity of the entire battery pack will be affected. To do this, we balance the mismatched cells. This article discusses the concept of cell balancing and some considerations. A lithium-ion battery pack usually consists of one or several battery packs connected in parallel, and each battery pack consists of 3 to 4 batteries connected in series. This combination can
