Analysis of lithium iron phosphate batteries

Source: 2020 - 04 - Tesla hits: 01 struck time admitted using lithium iron phosphate batteries in the afternoon, ningde era approaching tesla domestic programs, career experts say, tesla will use lithium iron phosphate batteries, namely the ningde times square lithium iron phosphate batteries. Mall jubilation immediately, ningde, yi wei can lithium, lithium battery, the day xuan high-tech, super capacitor feng yuan shares, new south wales, Germany nanometer lithium iron phosphate shock plate, etc. On February 18th, tesla said, using the cobalt free batteries, huayou cobalt industry, luoyang, han rui cobalt nickel industry industry decline limit. Market forecasts, can choose the lithium iron phosphate batteries, such as Germany nano board out of the market. A, the relevant data of the lithium iron phosphate lithium iron phosphate advantages: 1. High safety, LFP crystal structure stability, high thermal stability, with functions of high temperature, high calorific value of up to 350 ℃ 500℃。 2. Long cycle life, LFP cycle life can reach more than 2000 times, higher than the other data. 3. LFP cathode prices since the beginning of 2016 was 110000 yuan/ton down to 4. 20000 yuan/ton. Price drop is bigger, also makes the mainstream LFP battery system of enterprise tax price ( 0. 95 - 1. 5 yuan/wh) Under three yuan battery system of enterprise tax price ( 1. 1 - 1. 2 yuan/wh) 。 4. Higher group power: due to chemical functions such as data, LFP battery energy density limit exists bottleneck, but its security is higher, so the encapsulation structure is relatively simplified, lead to higher group of power. The shortcomings of the lithium iron phosphate: low energy density. Byd blade was introduced to improve the energy density of the lithium iron battery. King has leakage, a new generation of 'leaf cell by cell is graphic design, not only can make the unit volume energy density than conventional lithium iron batteries will be increased by 50%, still can make the vehicle battery life can reach more than 8 years, 1. 2 million kilometers, and plans for the next two years plan monomer energy density 180 wh/kg, system energy density 160 wh/kg, unit production capital fell by 30%. Lithium-ion batteries, lithium ion battery anode materials generally choose to define the power battery, ternary lithium batteries also have three elements, the influence of cobalt element crystal structure, is a kind of safety information scarcity of cobalt, cobalt resources concentrated in the Congo overlay, glencore announced cobalt production, cobalt prices continue to rise since January this year, tesla to reduce domestic capital model 3, only use cobalt free batteries. Earlier this year, tesla with global cobalt ore giant glencore ( 嘉能可) Cobalt is a long-term supply contracts negotiated, partly reflects the tesla's assessment, i. e. it can't get rid of the demand for cobalt in a short time. As mentioned earlier, tesla takeover of maxwell is to build a cell line, and discuss the super capacitor. Maxwell has several patents, including electrode formula, design and manufacturing skills, source materials, battery packaging design, as well as the interconnection between cells and cells, modules and modules. Maxwell's core skills, in the majority of the super capacitor is a proprietary product, solvent-free or dry electrode manufacturing process. The high yield of the winding process to produce high quality uniform thickness of electrode materials, and improve the product function and long service life. 3. Supplier recently constantly layout for car companies, more sensible approach is to choose a long-term to provide battery enterprise high function, high quality products, provide solutions for a variety of skills, combined with their own skills evolve iteration. 1. In recent years, ningde, developed a long-life battery power battery cycle life of domestic regulatory requirements must be reached more than 1000 times. Ningde era, however, the research and development of 'long life battery' beyond the professional standards, is expected to be applied in the new energy vehicles in the future. And the age of ningde positive charging pile layout, new energy and baicheng brisk new energy technology co. , LTD. Is established joint, develop urban super fast charging network operations issues, layout in charging pile shopping center. 。 September 2. 3 weft lithium can be said in a statement, the company has revealed plans to raise 2. 5 billion yuan, will invest in 'bean type TWS project with lithium ion batteries' and' high temperature of tire pressure testing and network USES lithium manganese battery project ', 'three yuan square power battery production research and test center project', increase liquidity.
