Last blog we introduced half of the the Iron Oxide Red Method for High-Density LFP Preparation Process, here is the part 2 of the process Process Step 2: Wet Milling (Sand Milling) Objective: To thoroughly blend iron oxide red (Fe₂O₃), lithium dihydrogen phosphate (LiH₂PO₄), and glucose through wet ultrafine milling, reducing particle size to the submicron or nanoscale level. This achieves homogeneous mixing of all components at the molecular level, providing an ideal reactiv

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

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

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

The exhaust holes are set on the tank cover and directly connected to the collection pipeline. The black mass after the crushing of LFP single cells and the purchased black mass of lithium iron phosphate batteries are first temporarily stored in the black mass warehouse, and then anhydrous iron phosphate is produced after leaching, impurity removal and roasting in the wet process workshop for the preparation of iron phosphate.

Waste NMC (nickel-manganese-cobalt) lithium battery packs and LFP (lithium iron phosphate) battery packs are processed through battery pre-treatment lines to obtain electrode powder. The NMC battery electrode powder and waste materials are further processed through acid leaching and solvent extraction lines to extract metals such as nickel, cobalt, and manganese, while the LFP battery electrode powder and waste materials are processed through acid leaching lines to extract li

Pulp preparation is an important process in the preparation of LFP batteries. The quality of the slurry directly affects the subsequent coating process and the performance of the battery. Therefore, improving the processing performance of LiFePO4 slurry plays an important role in enhancing the electrochemical performance and service life of the battery. The three commonly used modification methods, namely carbon coating, ion doping, and particle nanocrystallization.

When you plan to set up a lab-scale, pilot or commercial LFP plant, you are wondering what equipments/machines you need to buy and set up. But it needs to fit with your LFP cathode synthesis process. 90% of mainstream enterprises in China use the solid phase process to manufacture LFP cathode materials, of course it needs a liquid phase to synthesize the LFP precursor--FP (anhydrous iron phosphate ）first which we will post separately. The figure below shows the process flow d
