Talking about the relevant knowledge and application status of lithium batteries

Lithium batteries are composed of an outer shell, a positive electrode, a negative electrode, an electrolyte and a separator. The electrode material is undoubtedly the focus of attention and research. It is also widely used in our daily life, but at the same time, electrolyte is also an aspect that cannot be ignored. After all, the electrolyte, which accounts for 15% of the battery cost, is also due to the energy density, power density, wide temperature application, cycle life, and cycle life of the battery. Safety performance and other aspects play a crucial role. The electrolyte is an ionic conductor used for conduction between the positive and negative electrodes of the battery. It is made up of raw materials such as electrolyte lithium salt, high-purity organic solvents and necessary additives in a certain proportion. As the energy density of power lithium-ion batteries increases, the voltage will also increase. The higher the voltage, the stronger the analysis capability of the electrolyte. For the high nickel ternary system, the electrolyte company specializes in the detection of leakage current (that is, the current flowing through the insulator) and the dissolution of transition metal ions. The detection result stated that increasing the nickel content in the positive electrode material of the power lithium-ion battery will increase the dissolution of transition metal ions. The eluted transition metal ions will destroy the SEI film on the surface of the negative electrode after the negative electrode is reduced and precipitated. In addition, increasing the voltage will clearly increase the leakage current. In this way, the storage performance and cycle performance of the power lithium-ion battery in a high-temperature environment will be affected, and the increase in the nickel content in the material will also cause the safety performance of the power lithium-ion battery to decrease. These problems arising from the use of high-nickel materials and electrolytes are complicated to deal with, and the technical threshold is high. If the company does not have sufficient Ru0026D capabilities, it is difficult to make electrolyte products that match high nickel materials. This is an urgent issue in the lithium battery industry. Lithium batteries are widely used as emerging energy storage components. The application scope of lithium batteries has also evolved from small digital electronic products to large-scale energy storage products such as electric vehicles and energy storage power stations. According to data, the total demand for lithium battery cells in the world's three major application terminals increased from 34GWh in 2011 to 129.4GWh in 2016, with a compound annual growth rate of 30.64%. Among them, energy storage products for consumer electronics such as mobile phones and new energy vehicles are used on a larger scale. After years of development, it should be said that battery processing companies are the technical authority of lithium batteries, and they should have strong technical advantages in battery classification management and echelon utilization. The lithium battery industry has formed a complete industrial chain with a high degree of specialization and engineering, and the global lithium battery market has made considerable progress. In the early stage, the scale of lithium batteries for consumer electronic products is large, and the scrapped batteries have not yet been effectively managed. The future scrapping of lithium batteries should be a comprehensive consideration of all types of lithium batteries. Especially for the recycling of lithium batteries, a unified social recycling system should be formed, and the power lithium-ion battery consumption battery should be collected and distributed to the East Starway team leader. The recycling system of the city’s scrap batteries should be an important part of urban management. Only in this way can each department achieve professional division of labor and do their own work. As an intermediate link in the industry chain, it is difficult for vehicle companies to effectively monitor scrap batteries. As the energy storage of lithium batteries has become an important part of the entire social energy system, ensuring the sustainable production and marketing of lithium batteries and the effective recycling of core raw materials are an important part of ensuring the sustainable development of our social energy system. Especially for the core rare metals like nickel, cobalt and lithium, how can we ensure more efficient reuse? This is one of the sustainable goals of our linear industrial power.
