Structure and Working Principle of LiFePO4 Battery Structure and Working Principle of LiFePO4 Battery

On the left is the olivine structure of LiFePO4 as the positive electrode of the battery, which is connected to the positive electrode of the battery by the aluminum foil, and the middle is the polymer diaphragm, which separates the positive electrode from the negative electrode, but the lithium ion Li+ can pass through it, while the electron e- cannot pass through it, and on the right is the polymer diaphragm. In the center is a polymer diaphragm, which separates the positive electrode from the negative electrode, but allows the passage of the lithium ion Li+ but not the electrons. Between the top and bottom of the battery is the electrolyte, and the battery is hermetically sealed in a metal case. When a LiFePO4 battery is being charged, the lithium ion Li+ in the positive electrode migrates through the polymer diaphragm to the negative electrode; during discharge, the lithium ion Li+ in the negative electrode migrates through the diaphragm to the positive electrode. Lithium-ion batteries are named for the migration of lithium ions back and forth during charging and discharging.

Main Performance of LiFePO4 Battery Main Performance of LiFePO4 Battery

LiFePO4 battery's working voltage is 3.2 V, termination charging voltage is 3.6 V, termination discharging voltage is 2.0 V. Due to the difference in the quality and technology of the cathode, anode, and electrolyte materials used by different manufacturers, there are some variations in the performance of LiFePO4 batteries. For example, the capacity of the same model (standard battery in the same package) may vary greatly (10% to 20%).

LFP Battery Process

Lithium iron phosphate (Cathode material)

Molecular formula LiFePO4, also known as lithium iron phosphate, lithium iron phosphorus, abbreviated LFP (three-dimensional olivine structure)

LFP Power Process

Lithium iron phosphate (Cathode material)

Synthesis of lithium iron phosphate materials can be divided into wet and wet process. The synthesis of lithium iron phosphate materials can be divided into two types, wet and dry, with the technology focusing on formulation and firing control. Typical manufacturing plants are equipped with mixers, atmosphere firing furnaces, mills and sieves.

LiCoO2 vs. LiFePO4

Lithium-cobalt batteries have a layered structure, while lithium-iron batteries have a three-dimensional olivine structure, which makes the former prone to structural disintegration during fast charging or discharging, while the latter does not have problems during charging and discharging. Although the theoretical capacity of lithium-cobalt-oxygen cathode materials is as high as 274mAh/g, it can only reach 151 mAh/g in practice, while lithium-iron-phosphate cathode materials only have a theoretical capacity limit of 180mAh/g, but in practice they can reach about 140-150 mAh/g.

Taiwan LFP Value chain

is the earliest company in Taiwan to invest in R&D. Its newly-developed solution process can oxidize raw materials and acid into a solution to create finer particles, making it easy for dopant ions to be evenly distributed, and improving the discharge performance. Shanghua claims that its performance in terms of grams of electric capacity, as tested by battery makers, is better than that of Phostech. The patent is for a composite-phase LiFePO4/Li3V2 (Li3V2) composite-phase compound, which has a capacity of about 1.8 mAh/g, but in practice it can reach about 140 to 150 mAh/g. Li3V2(PO4)3

Method of manufacturing lithium battery cathode materials and application. Due to the addition of vanadium, the cost is higher, and due to the increase in impurities, the stability is reduced and the risk is higher.

Hongse Technology

Hongse Technology, which was invested by founder Shi Zhenrong's Wisdom Venture Capital, was originally a manufacturer of testing instruments and equipment for solar energy and panels. Last year, the company was commissioned by the Industrial Technology Research Institute (ITRI) to carry out trial production of lithium iron phosphate (Li-FePO4) cathode materials in the laboratory, and the output of nano-grade Li-FePO4 cathode materials reached high performance levels. Therefore, it completed the transfer of patented technology by the end of 2008, and this year, it will first complete a 20-ton per month capacity production line.

Faiplast Evergreen Technology

Evergreen Technology holds 49% of the shares, and Formosa Plastics Biomedical holds 51% of the shares, and the monthly production capacity of lithium-iron battery cathode materials will be expanded to 4,000 tons by the end of next year from 1,200 tons by the end of this year to become the world's largest, and the company also plans to set up lithium-iron battery core factory in a joint venture with CKE, so as to achieve the integration of the industrial chain step by step. The production of lithium-iron battery primary materials requires a lot of electricity, and Formosa Plastics has its own steam and electricity*** production equipment, so the cost of electricity is relatively inexpensive; at the same time, Formosa Plastics will have its own group of large steel mills in the production process, which will produce scrap iron (iron oxide), which can be used for the production of lithium-iron battery primary materials, which is tantamount to the recycling of waste materials. Li-Fe battery module is the next business that Eternal will invest in, and we have already developed Li-Fe battery system for forklift trucks (using 128 pieces of 40138 Li-Fe battery cells produced by Sunrise Semiconductor); solar Li-Fe battery storage system, UPS backup battery packs, and Li-Fe battery packs for electric golf carts...and other products.

LiKai Power

LiKai Power has obtained a patent on "Composite Materials Applicable to the Manufacture of Positive Electrodes for Secondary Batteries and Batteries Produced Therefrom", which features the use of a nanocoating process to produce an olivine structure different from that of Dr. Goodenough's. The patent produces an olivine structure. This patent features a nano-coating process to create an olivine structure different from Dr. Goodenough's. The advantages of the battery powders produced by this patent include improved electrical conductivity, as well as increased electrical capacity and power. The company's business strategy is similar to that of A123, in that it finds its own cell manufacturers to manufacture cells and sells lithium-iron-phosphorus (Li-FePO4) battery cells.
