Analysis on the use and performance characteristics of ternary lithium ion batteries and lithium iron phosphate batteries

Lithium manganese oxide batteries can reduce the rare cobalt element, which must be used in ternary lithium-ion batteries. At the same time, as lithium-ion battery systems have received less attention in the market, lithium-ion manganate battery systems have begun to cannibalize the market. Relying on the cost advantage and performance improvement, there has been an impact on the new energy passenger car market dominated by iron and lithium. 1. The support of lithium manganate in the first three batches of power lithium battery catalog is the third largest battery system. The first three batches of new energy vehicle catalogs have announced 1,328 products. Among the supporting power lithium batteries, lithium iron phosphate is still the most mainstream supporting battery system, with an application model reaching 55%. The ternary lithium-ion battery application model accounts for 25%. Because of its high energy density and cost control in line with policy planning, it is considered to be the mainstream power lithium battery application system in the future. Prior to this, the market paid less attention to the lithium-ion manganate battery system. The first three batches of supporting models accounted for 16%, which has also become a force that cannot be ignored. Ternary lithium-ion battery and lithium iron phosphate 2. Lithium manganate has become another important application system for mainstream pure electric models. The first three batches of new energy promotion model catalogs, the application system of lithium manganate is still plug-in hybrid vehicles As an important application field, what cannot be ignored is that lithium manganate is an important application of pure electric vehicle models, which are 36 years old, and lithium manganate supports 17% of the models. The most common application of lithium manganate in pure electric bus models is BAIC New Energy, followed by Xiamen King Long and CSR. In addition, Zhongtong, Yutong, Yangtze River, Ankai, Shenlong, Yaxing, etc. have all begun to apply lithium manganate in pure electric bus models. Lithium manganese oxide has become another application system for mainstream pure electric vehicles. 3. Lithium manganese oxide has a strong price advantage. Under the dual use of new energy vehicle subsidies and market promotion, in the three major power lithium-ion battery systems, manganese The price advantage of lithium oxide will be particularly obvious. After experiencing the skyrocketing cobalt price, the price of ternary materials still remained at a high level of 1.8-19 million yuan/ton. Due to the high expectations of ternary materials and the limited release of output, prices will be adjusted, but they will remain high. The market price of mainstream lithium iron phosphate remained at around 85,000 yuan/ton, a decrease of 20,000 yuan/ton or 20% from the previous year. Lithium manganate, due to the sufficient supply of materials at the front end, the material price is only 50,000 yuan/ton. The biggest impact is on its lithium carbonate. The release of lithium mineral energy is in Qinghai Province. The future price fluctuations of lithium manganate can be expected. 4. Lithium manganate has excellent performance indicators and a high degree of integration with policies. The first three batches of new energy promotion model catalogs announced. The energy density of lithium manganate batteries for pure electric vehicles is more than 115wh/kg, which changes the previous market for manganese acid. Lithium energy density is low, the starting point of research (SPIR) Peng Meng Clark, star constant, several lithium manganate batteries, such as the company's research, found that the SOC cycle of lithium manganate batteries can reach 2000 degrees Celsius, and there is a ternary system. Under the dual requirements of energy density and fast charging performance, the power performance, discharge rate performance, low temperature performance and high voltage frequency characteristics of lithium manganate batteries can fully meet the market demand. In the early days, battery packs mainly refer to the processing, assembly and packaging of lithium-ion battery packs. The process of assembling lithium-ion battery cells into a group is called a battery pack. The battery pack can be a single battery or a series-parallel lithium-ion battery pack. The packaging includes auxiliary materials such as battery packs, bus bars, flexible connections, protective plates, outer packaging, output (including connectors), barley paper, and plastic brackets. The lithium-ion battery pack system uses a mechanical structure to connect multiple single cells in series and in parallel, taking into account the mechanical strength, thermal management, and BMS matching of the system. Its important technology is embodied in the overall structure design, welding and processing process control, protection level, active thermal management system, etc. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
