Technical characteristics and development trends of lithium battery materials

Technical characteristics and development trends of lithium battery materials The lithium battery industry requires the integration of multiple technologies, including electrochemical technology, processing technology, electronic technology, and material development technology. Lithium batteries not only need to be continuously developed in theory, but also have correspondingly high processing requirements. We must rely on excellent equipment and factory conditions as well as high-quality technical workers to be able to process qualified lithium batteries. The following author analyzes the technical characteristics of Xianyi.com and the technological development trend of lithium battery materials. From the technical barriers of raw materials, lithium battery professional technology separator> anode material> electrolyte> anode material. However, the central problem that always prevents the use of lithium battery industrialization strategies is the anode material.On the one hand, the anode material of the lithium battery has the highest capital, which reduces the source of the anode material of the lithium battery. On the other hand, the cathode material is the electrochemical performance of the lithium battery. The decisive factor is that the current anode materials cannot fully meet the requirements of the widespread use of cheap electric vehicles and industrial storage. Cathode materials are the most important raw material for lithium batteries. Different cathode materials have their own advantages and disadvantages. According to the needs of cheap products, the types of cathode materials selected are different. The functional requirements for lithium battery cathode materials in the consumer electronics field are mainly focused on the energy density and safety of lithium batteries. The functional requirements of power battery cathode materials are high voltage, high energy, high power, and wide temperature range. Lithium iron phosphate, lithium manganate and ternary materials are important raw materials for the positive electrode materials of power lithium batteries. In terms of power lithium-ion batteries, lithium titanate is a new development direction. The technical characteristics and development trends of lithium battery materials. The technology and market of anode materials are relatively outdated. Primary carbon materials and graphite anode materials are bound to have mainstream advantages in terms of negative electrode funding speculation. The multiplier function of traditional graphite anode materials is difficult to meet the requirements of lithium batteries. In the field of consumer electronics, to increase the energy density of batteries, new high-capacity cathode materials represented by silicon-carbon (si-c) composite materials are the future development trend. Diaphragm processing technology has the highest barrier. The most important diaphragm materials on the market are polyethylene (PE) and polypropylene (PP)-based polyolefin diaphragms. The future development trend of the diaphragm career is thinner and safer. With the rapid rise of lithium battery applications in consumer electronics, electric vehicles and other categories, the future storage layout, before the explosion of lithium battery separators, breakthroughs in product functions and quality in demand, the future trend of separators is to satisfy high power, large capacity, and long life. Cycle, safe and reliable function requirements. The electrolyte is usually composed of high-purity organic solvents, electrolyte lithium salts, necessary additives and other materials.Under certain conditions, according to a certain manufacturing industry, the electrolyte has the largest proportion of the electrolyte cost and the highest technical barrier. Links are now monopolized by Japan and South Korea first. Lithium hexafluorophosphate is the most important lithium battery electrolyte on the market. The future development trend of electrolyte is to meet the requirements of high voltage, wide temperature range and high safety. At present, from the perspective of technological development, there are three major development trends in lithium battery material technology: (1) the development of large-capacity lithium-ion power lithium-ion batteries for electric vehicles; (2) the development and application of new high-functional electrode materials, especially Development of high-functional anode materials; (3) Further reduce the cost of lithium batteries and improve battery safety.
