Process Route Overview The Iron Oxide Red Method (hereinafter referred to as the "Iron Red Method"), also known as the carbothermal reduction iron red method, is a process route that uses ferric oxide (Fe₂O₃) as the iron source, composite salts such as lithium dihydrogen phosphate (LiH₂PO₄) as the lithium and phosphorus sources, and organic carbon sources like glucose as both the reducing agent and conductive coating agent. Through a high-temperature solid-state carbothermal

When conducting a cost analysis of lithium carbonate, it is essential to focus on its diversified process routes and their corresponding cost structures, as well as to understand the current market landscape characterized by significant cost disparities and ongoing industry consolidation.

The Cost Analysis of producing LFP needs to focus on its cost structure, which consists of two major components: core raw materials (especially lithium carbonate) and processing fees, as well as the current structural differentiation in the industry characterized by 'shortage in the high-end segment and oversupply in the low-end segment'. The table below summarizes the cost composition and recent market conditions of LFP, helping readers quickly establish an overall understan

In the new energy battery sector, lithium iron phosphate (LFP) cathode materials have continuously evolved around three core objectives: enhancing energy density, optimizing costs, and balancing performance. Today, Generation 3, Generation 4, and Generation 4.5 products coexist in the market. Significant differences exist from technical specifications to mass production, which directly determine a battery's range, fast-charging capability, and application scenarios. As a tech

The mainstream synthesis processes for the preparation of FP include the ammonium method, sodium method, and iron method. Although all three iron phosphate synthesis processes are based on co-precipitation, there are fundamental differences in the precipitation crystallization and growth mechanisms due to variations in raw material systems and microscopic synthesis environments. These differences lead to significant distinctions in the microscopic morphology, physical propert

From risk management to system implementation In today's rapidly evolving new energy battery industry, the quality of Lithium Iron Phosphate (LFP), a core cathode material, directly determines the safety and service life of batteries. Metal magnetic impurities are precisely the "invisible killers" threatening LFP quality—they can not only cause cell short circuits and failures but may also trigger severe safety accidents such as electric vehicle fires. According to data from

This is the globally launched semi-solid-state battery in the MG4, and it has several impressive features. First, its electrolyte content is only 5%, making it almost a purely solid-state technology. Second, it has passed a 10-nail penetration test, which has never been done in the industry before. This 10-nail penetration test has three remarkable aspects: 1. The number of nails is relatively large, with as many as ten nails ; 2. These nails completely penetrate the separat

On August 5, one month after MG announced its "All in on New Energy" strategy, the all-new MG4 began pre-sales. One variant of this model will be equipped with a semi-solid-state battery developed by SAIC and be the first globally to enter mass production. Its price will be announced in September, with volume deliveries scheduled within the year. As the solid-state battery concept continues to gain traction, the application of semi-solid-state batteries is also riding this

On August 9, the Ministry of Industry and Information Technology (MIIT) publicized the 398th batch of the "Road Motor Vehicle Manufacturer and Product Announcement". A total of 65 vehicle models from 19 enterprises were announced, including several popular models from key brands. Among them, three new models equipped with Qingtao Energy's semi-solid-state batteries were included in the MIIT list: the SAIC MG MG4 (Manganese-based semi-solid-state battery), the Nanjing Automobi

The iron to phosphorus ratio is the critical factor in the quality control of lithium iron phosphate production. Precise control of the iron-to-phosphorus ratio isn't a single point of control, but rather a systematic process throughout the entire production process . It tests a company's depth of understanding of the process and the sophistication of its process control. Below I will divide it into two parts: "Precise Control Method" and "Deviation Solution",Iron to Phosphor
