Demand for CR2430 battery electrolyte and its technical analysis

Demand for CR2430 battery electrolyte is growing rapidly, and technology is maturing. CR2430 battery materials include four types of positive electrodes, negative electrodes, diaphragms, and electrolytes. Electrolytes affect factors such as energy density, power density, wide temperature application, cycle life, and safety performance of lithium batteries. Driven by the development of downstream markets, the CR2430 battery market will continue to maintain a rapid growth trend, and the electrolyte market will also be driven, with a promising future. Rapid growth in demand for CR2430 battery electrolytes After years of continuous process improvements and technological accumulation, my country's electrolyte products have not only continued to grow in terms of output, but also reached international advanced levels in terms of product quality. In recent years, the sales volume of my country's CR2430 battery electrolyte market has grown rapidly, from 16,800 tons in 2011 to 88,800 tons in 2016, with an annual compound growth rate of 39.51%. The demand for lithium batteries is growing rapidly. With excellent performance, lithium batteries have gradually replaced nickel-hydrogen and nickel-cadmium batteries and have rapidly become popular in the field of mobile power supplies. In the past few years, the global CR2430 battery production has maintained rapid growth, from 5.95GWh in 2003 to 33.5GWh in 2012, with an average annual growth rate of 21.6%. At present, it is mainly used in mobile phones, notebooks, power tools and energy storage. China's CR2430 battery production has grown rapidly. From 2008 to 2013, China's CR2430 battery production increased from 1.03 billion to 4.77 billion, an increase of 3.6 times, with an average annual compound growth rate of 30%. With the explosive growth of the three major demands for electric vehicles, electric bicycles and energy storage batteries, the demand for lithium batteries will continue to grow rapidly in the future. The CR2430 battery electrolyte market has great potential. In recent years, lithium batteries have developed rapidly, and the demand for lithium hexafluorophosphate has increased significantly. Domestic companies such as Duofuduo, Jiujiujiu, and Tianci Materials have successively achieved mass production of lithium hexafluorophosphate through external technology introduction and independent research and development. However, as supply increases, demand has not increased simultaneously, resulting in overcapacity and the rise of price wars. The price of lithium hexafluorophosphate has fallen by more than half since 2013. Although the selling price and gross profit margin of lithium hexafluorophosphate and electrolyte have dropped sharply, according to the company's financial statements, the sales volume of electrolyte has increased significantly compared with previous years, benefiting from the development of downstream new energy vehicles and the stable growth of traditional consumer electronic products. Judging from the global sales volume of electrolytes in recent years, it has shown a stable and rapid growth trend. Although the demand for traditional 3C lithium batteries has gradually slowed down, with the development of the new energy vehicle industry, it has brought new impetus to the growth of the CR2430 battery industry, thus driving the growth of the electrolyte industry. CR2430 battery electrolyte technology continues to mature. After years of development, domestic CR2430 battery electrolytes have become the most technologically mature variety among the four major materials. They have been exported in large quantities and account for more than 50% of the global share. The recognition of international manufacturers proves the quality of domestic electrolytes. With the start of demand for electric vehicles, it will not be too difficult for leading electrolyte companies with strong R&D capabilities to enter this field. In addition, the popularization of electric vehicles still requires a price reduction of power batteries, so there is huge room for domestic electrolyte substitution. The manufacturing and R&D levels of leading Chinese electrolyte companies have rapidly improved in recent years, and the quality of their products has rapidly approached the international advanced level. With the advantage of cost-effectiveness, China's CR2430 battery electrolyte has rapidly increased its global market share in recent years. Products of companies such as Jiangsu Guotai, Xinzhoubang and Tianjin Jinniu have entered the international market. According to our understanding, the patent issue of electrolyte formula is also an important reason that troubles Chinese companies to go global. At present, some electrolyte formula patents are in the hands of Japanese manufacturers such as Mitsubishi and Ube, which has become a key obstacle to Chinese electrolytes entering the Japanese market. At present, Jiangsu Guotai and Xinzhoubang have increased their research and development efforts on formulas. If they can break through Japan's patent blockade and open up the Japanese market, the market space will increase significantly. Considering that the current global power lithium batteries are mainly produced in Japan, breaking through the patent blockade will be of greater significance. Development trend of CR2430 battery electrolyte technology 1. High specific energy type electrolyte The pursuit of high specific energy is currently the largest research direction of lithium batteries, especially when mobile devices occupy an increasing proportion in people's lives, and battery life has become the most critical performance of batteries. 2. High power type electrolyte At present, it is difficult for commercial lithium batteries to achieve high-rate continuous discharge. The main reason is that the battery ear heats up seriously, and the internal resistance causes the overall temperature of the battery to be too high, which is prone to thermal runaway. Therefore, the electrolyte needs to be able to suppress the battery from heating up too fast while maintaining high conductivity. For power batteries, achieving fast charging is also an important direction for the development of electrolytes. 3. Wide-temperature electrolyte batteries are prone to electrolyte self-decomposition and intensified side reactions between materials and electrolyte parts at high temperatures; while at low temperatures, electrolyte salts may precipitate and the impedance of the negative electrode SEI film may increase exponentially. The so-called wide-temperature electrolyte is to give the battery a wider working environment. 4. Safety The safety of electrolyte batteries is mainly reflected in combustion and even explosion. First of all, the battery itself is flammable. Therefore, when the battery is overcharged, over-discharged, short-circuited, when it is punctured or squeezed by the outside world, and when the outside temperature is too high, it may cause safety accidents. Therefore, flame retardancy is a major direction for the research of safe electrolytes. 5. Long-cycle electrolytes Since there are still great technical difficulties in the recycling of lithium batteries, especially power batteries, improving the life of the battery is a way to alleviate this situation. There are two main research ideas for long-cycle electrolytes. One is the stability of the electrolyte, including thermal stability, chemical stability, and voltage stability; the other is the stability with other materials, which requires stable film formation with the electrode, no oxidation with the diaphragm, and no corrosion with the current collector. Future development and improvement direction of CR2430 battery electrolytes The core of CR2430 battery electrolytes is material purification technology and formulation technology. The purity requirement is high, so high requirements are placed on the production process and process control of CR2430 battery companies. Lithium batteries are widely used, and lithium batteries with different technical routes and different application fields will also have different requirements for electrolytes. Therefore, electrolyte manufacturers need to cooperate with downstream customers to develop, thus forming a relatively stable cooperative relationship. It can be said that every improvement in the performance of lithium batteries is inseparable from the progress of electrolytes to match it. Improving the voltage and stability of lithium batteries is the future development direction. In the field of small batteries, high energy density is emphasized. For electrolytes, increasing the working voltage to adapt to higher energy density requirements is the future development direction. At present, the electrolyte voltage has gradually developed from 4.35 volts to 4.4 volts, and gradually developed towards 4.5 volts, 4.75 volts and even 5 volts. Fluorinated carbonate and dinitrile additives are widely used. In the field of large-scale power batteries, they often work outdoors and have high requirements for high and low temperature performance. Since lithium hexafluorophosphate has poor thermal stability and is easily decomposed by heat, it is necessary to add stabilizers to the electrolyte to improve the cycle performance. It is easier said than done, and there are high hidden thresholds for CR2430 battery electrolytes. Based on the above analysis, we believe that the core of CR2430 battery electrolytes is purification process and formula research and development. The entry threshold seems not high, but it is easier said than done. There are not many manufacturers who can make high-quality electrolytes to meet the needs of international customers. Continuous research and development is required to keep up with customers' increasingly high performance requirements for electrolytes. Therefore, there are high hidden thresholds in the industry. With the development of the new energy vehicle market, the demand for power batteries is very large. We need to stand higher to meet the needs of new energy vehicles and look at the demand for electrolytes from the perspective of automobiles, which will give us a new understanding of electrolytes. Therefore, it is recommended that the industry be integrated. Existing CR2430 battery electrolyte factories and battery factories must be integrated together to meet the battery needs of new energy vehicles. CR2430 battery electrolyte is one of the four key raw materials of lithium batteries and has a significant impact on the performance of lithium batteries. The technical threshold of electrolyte is not high, but the hidden threshold is high. In order to solve problems such as battery safety, electrolytes are also constantly updated. CR2430 battery electrolyte manufacturers should continue to accelerate their development to meet customer needs.
