Analysis on the Application of Lithium Manganate Cathode Materials in Power Lithium Ion Batteries

Application of lithium manganate anode materials in power lithium-ion batteries Since the beginning of this year, as the number of triads in power lithium-ion batteries has gradually increased, it has gradually surpassed the market share of lithium iron phosphate due to its high energy density. But its safety and recycling function still restrict its further development. As a traditional positive data, lithium manganate adheres to its original advantages. Through technological innovation, increased cycle times, new capacity, enhanced high and low temperature functions, etc., it can completely occupy a place in the new energy market segmentation category. Hunan Haili Lithium Battery Technology Co., Ltd. (formerly) Hunan Research Institute of Chemical Industry has a solid foundation of function data, relying on years of research and development skills to deposit the concentration of manganese series products, and launched the main product power lithium manganese acid type 101 national independence Intellectual property products are based on the scientific and technological achievements of the 863 plan, and independent research and development of high-quality chemical manganese dioxide as manganese source data, selection of technologically advanced processing technology and equipment, and active material sintering concept innovation, and optimization of the precursor lithium manganese oxide In the solid phase reaction process, the crystal structure of lithium manganate is stable, the processing function is good, the discharge capacity is high, the specific function, the cycle function and the good high temperature and low temperature function are widely used, and it is used as an anode material alone or in combination. Different ternary data can be effectively used in different categories. The energy density of pure manganese batteries now has more than 145 individual customers. It has been successfully applied to urban logistics vehicles, shared cars, cars in low-speed and large-scale energy storage power stations, and solar storage. system. A domestic battery manufacturer used 101-type lithium manganate in grid energy storage equipment and successfully processed 2-16kwh modular batteries. The battery has passed the long-life test, and its specific capacity, cycle life, battery energy and power and other important indicators surpass similar products of American companies. After third-party testing, the prototype is cycled 3000 times (100% DOD), and the capacity attenuation is <5%. A power lithium-ion battery manufacturer uses 101-type lithium manganate for power automobile lithium batteries. The battery exhibits outstanding charge and discharge power, high and low temperature functions, multiplier functions, and use functions. Battery charge and discharge power above 99.0%; -20℃ discharge capacity/room temperature 1C discharge capacity>85%, 55℃ discharge capacity/room temperature 1C discharge capacity>100%; 3C discharge capacity/1C discharge capacity>98.5%; battery at room temperature After being fully charged and placed for 28 days, the capacity continuity rate is ≥85%. The capacity recovery rate is ≥99%. A certain power lithium-ion battery processing company uses 101-type lithium manganate in solar energy storage equipment. The battery has good multiplier functions, cycling functions and high-temperature cycling functions. At room temperature, the first discharge specific capacity is greater than 100mAh/g, the proportion of the first discharge channel is greater than 95%, the proportion of 5c/1c discharge capacity is greater than 97%, the proportion of 3000c cycle capacity is greater than 80%, and the proportion of 5c2000 cycle capacity More than 80%. Under the condition of high temperature of 60℃, the capacity continuity rate of the 300th cycle of the 1C multiplier is greater than 80%, and the capacity continuity rate of the 600th cycle is greater than 73%. Hunan Haili Lithium Battery Technology Co., Ltd. is a large state-owned company in Hunan Haili High-tech Industry Group Co., Ltd., a Shanghai A-share main board listed company (600731). It has undertaken too many important issues at the national, provincial and ministerial levels, has many national invention patents, has strong technical force and high-tech products. The company's 16,000 tons/year plans to build the first phase of lithium battery cathode materials. Products include lithium nickel cobalt manganese acid (sliding) 111 type, 523 type, 622 type, lithium manganate 101 type, 102 type (high pressure, 1c cycle capacity 500 Multiplying rate of 80%), 103 years (1c bicycles more than 300 times) (high voltage) and 202#, 201# lithium manganate (ordinary) products, can be customized according to different categories and use different products of cathode materials to meet different requirements Customer demand.
