Analysis of silicon carbon anode material lithium battery

The silicon-carbon cathode material lithium battery is a wonder among lithium batteries. In recent years, electrochemical energy storage technology represented by lithium batteries has the characteristics of high energy, active azimuth and rapid care. It satisfies the technical requirements of the power system and the turning trend of the smart grid. It has become the fastest growing energy storage technology in the field of electric power research. Lithium batteries are rocking chair batteries whose positive and negative electrodes are composed of two compounds or substances, which can be deintercalated many times. When charging, the positive electrode material lithium and lithium ions are inserted into the cathode of the electrolyte through the separator, and the positive electrode reacts with oxidation, and the discharge is reversed. With the reverse of battery electrode materials, lithium battery technology has been rapidly reversed. At present, lithium-cobalt batteries have been expanded to ternary, lithium manganate, lithium iron phosphate, and silicon-carbon negative battery systems. The new silicon-carbon cathode lithium battery breaks through the inherent limitations of graphite as a negative electrode, and its performance is significantly better than traditional lithium batteries. It has become one of the most promising energy storage batteries. It can be seen that the cathode material sintering furnace is an important part of the cathode material sintering machine. The cathode material sintering furnace developed by Jiangsu Fenggu Energy Saving Technology Co., Ltd. is mainly used for the sintering test of industrial raw materials, especially the sintering test of lithium battery cathode materials. The equipment has compact structure, fast heating speed, good sealing performance, uniform furnace temperature, good sintering effect, novel design and simple operation. The core advantage of the cathode material sintering furnace series is that the internal tank plan can be replaced, which can meet the test requirements of different materials. Cathode material sintering furnace is suitable for laboratory experiment setting, universities, research institutes, industrial and mining companies or small batch processing, especially suitable for silicon carbon cathode materials. Sintering test is the best choice for this product. Safe and safe. Because of the potential of high silicon carbon anode material lithium, the composition and accumulation of lithium metal are prevented during the sintering process. Because the equilibrium potential is higher than the potential for recovery of most electrolyte solvents, it is not an electrolyte, and the solid-liquid interface does not form a passivation film. For many side-uses, greatly improving safety, safety and safety of lithium materials are the most important policy in the sintering process. Said a senior engineer from Jiangsu Fenggu Energy Saving Technology Co., Ltd. Long cycle life. Compared with graphite materials commonly used in lithium batteries, silicon-carbon cathode materials hardly shorten or expand during lithium charging and discharging and lithium removal. This material is called a zero-strain material, which can prevent damage to the electrode structure caused by the volumetric strain of the battery when lithium ions are removed or inserted. Has a good circulation function. According to the test data, the average cycle life of lithium iron phosphate batteries is 5500-7000 times, while the average cycle life of silicon carbon anode batteries exceeds 30,000 times. Good heat resistance. Generally speaking, the charging and discharging temperature of an electric vehicle is -5°C. Silicon carbon anode batteries have excellent temperature resistance and durability. Generally charging and discharging between -50c and 80c, whether in the cold north or the hot south, will not be affected by the impact of the battery, and the concerns of users will be resolved. It is precisely because of these interests that silicon-carbon anode batteries have become a dazzling wonder in the development of lithium battery technology. Technical transformation reduces costs. In order to meet the demand for lithium-ion batteries for electric vehicles, the original silicon-carbon cathode lithium battery was developed. Although advanced silicon carbon anode battery companies are beginning to enter the field of energy storage, there is currently no lithium titanate battery specifically designed for large-scale energy storage applications. The first problem in large-scale applications of silicon-carbon cathode batteries is cost. At the beginning of the project, it was 4-6 times more expensive than lithium iron phosphate batteries. Yang said that the price of silicon-carbon anode batteries is still very high. Although they are much better than existing lithium batteries, they are also economically cost-effective. Promote the promotion of lithium titanate batteries in the market. Statement: Some pictures and content of articles published on this site are from the Internet.
