  Basic principles and composition of sodium-ion batteries 1. Overview of  sodium-ion batteries In various energy storage systems, lithium-ion batteries are widely used due to their advantages such as high energy and power density, long life, environmental friendliness and lack of memory effect. Since the successful commercialization of lithium-ion batteries in 1991, they have played an important and irreplaceable leading role in many important fields, such as consumer electronics industry, new energy vehicles, large-scale energy storage, etc. At present, although the relevant technologies and processes of lithium-ion batteries have matured, and lithium-ion batteries have unique advantages in various fields, the low safety, low cycle life, low temperature resistance and high cost of lithium-ion batteries cannot be ignored. Therefore, it is urgent to develop low-cost batteries with high safety, high reliability, cold and heat resistance as alternatives to lithium-ion batteries....

  Safety analysis of hydrogen for fuel cell vehicles Hydrogen energy, as a clean, efficient, safe and sustainable new energy, is regarded as the cleanest energy with the greatest development potential in the 21st century and is the strategic energy development direction. 1. Is hydrogen safe? The safety performance is no less than that of common fuels and can meet application requirements. The characteristics of hydrogen are analyzed as follows. The leakage rate of hydrogen is faster than that of common fuels, but the total leakage energy is not high. Hydrogen has a high diffusion coefficient and buoyancy, and the concentration can be quickly reduced when leaking. The explosion limit range of hydrogen is wide, but the explosion energy is very low and does not produce thick smoke and haze. Hydrogen embrittlement can cause metal embrittlement cracks, which can be avoided by selecting appropriate materials for protection. 2. Is the storage and transportation of hydrogen safe? Mainly tr...

  1.Definition and classification Definition:  Hydrogen compressors   are equipment that compresses hydrogen to increase its pressure. They are widely used in hydrogen fuel cell vehicles, hydrogen energy stations, hydrogen storage systems and other fields. Classification: According to the working principle and internal structure, hydrogen compressors can be divided into two categories: mechanical compressors and non-mechanical compressors. Mechanical compressors are further subdivided into liquid-driven compressors, diaphragm compressors, linear compressors and ionic liquid compressors; non-mechanical compressors include cryogenic liquid pumps, metal hydride compressors, electrochemical hydrogen compressors and adsorption compressors. 2.Working principle The working principle of hydrogen compressors is mainly based on the principle of gas compressibility, and the compression and pressurization of hydrogen are achieved through the reciprocating motion o...

The vanadium flow battery is a redox battery with vanadium as the medium. Its full name is   Vanadium Redox Flow Battery   (VFB), which was proposed  by Marria Kacos of the University of New South Wales, Australia in 1985. The vanadium battery energy storage system has high energy storage efficiency and can be widely used in power plant power storage. It can store excess electricity under low load and input electricity into the grid as an auxiliary power source under high load, reducing energy waste. Vanadium batteries can store energy for a long time. When an emergency occurs, the stored electrolyte can be immediately put into use, which is much faster than emergency power generation devices. It can be used as an emergency power supply after a power outage. Since intermittent energy sources such as wind and photovoltaics have poor power generation stability, voltage fluctuations and flickers, and cannot form a stable power supply, a high-efficiency, low-cost energy stora...
