According to media reports, according to media reports, the behavior of tiny particles in lithium battery electrodes conducted by Stanford University in the United States recently showed that the battery is quickly charged and then used for high-power fast power consumption. The damage to the battery from work may not be as bad as the researchers expected, and the benefits of slow charging and power consumption may be overstated.
The results of this study challenged the prevailing view that "supercharged" batteries are more demanding than slow-charged electrodes, from researchers at Stanford University and the US Department of Energy's SLAC National Accelerator Laboratory at Stanford University's Materials and Energy Sciences (SIMES). Said. They also say scientists who may be able to alter or change the battery or charging electrode to enhance unified charging and discharging processes, thereby extending battery life.
"The details of the chemical processes taking place in the electrodes during charging and discharging are just one of many factors that determine battery life, but this factor has not been fully understood before this study," said Senior Researcher, Stanford University Materials Science And William Chueh, an assistant professor at the School of Engineering, SIMES said. “We have discovered a new perspective on battery aging.†These findings can be directly applied to oxide and graphite electrodes used in many modern commercial lithium batteries.
An important reason for battery loss is the expansion and contraction of the positive and negative electrodes as they absorb and release ions from the electrolyte during charging and discharging. In this study, scientists have studied positive electrodes composed of billions of lithium iron phosphate nanoparticles. If most or all of the ions are actively involved in the charging and discharging process, they will absorb and release ions relatively uniformly. But if only a small number of particles absorb all the ions, they are more likely to crack and damage, reducing battery life.
Production Introduction
Silicon Carbide fine powder is a type of the silicon carbide, which has Silicon Carbide Sand and silicon carbide particle size. According to different sizes to devide different mesh. The size generally divided into 8 # -320 #, the larger the model, the finer the particle size. Generally referred the size than 320 # as Silicon Carbide Powder. Silicon carbide particle size sand is divided into black and green two kinds, which are the ideal abrasive, mainly used for polishing, making grinding wheel, cutting sheet and other abrasive industry.
Black and Green Silicon Carbide has high purity, hardness characteristics. It mainly used in abrasive, refractory and electronic industries. The particle size has 0-10mm, 0-20mm, 0-50mm, 1-3mm, 3-5mm, 5-8mm, 1-10mm and so on.
The silicon carbide with high hardness, chemical stability and toughness characteristics, so silicon carbide mainly used to manufacture bonded abrasive, coated abrasive and free grinding. Using this raw materials to process the glass, ceramics, stone, Cast iron and some non-ferrous metals, hard alloys, titanium, high-speed steel cutting tools and grinding wheels.
Each Grain size and packaging can be processed according to customer`s requirements.
