Abstract: This method recycles iron phosphate slag, which is produced as waste during lithium iron phosphate battery recycling processes that contain leaching or crushing for the sole extraction of lithium. This method extracts aluminum phosphate, iron phosphate, and lithium phosphate from the waste slag. The recycling process comprises these steps: (a) extraction of aluminum phosphate through addition of sodium hydroxide; (b) removal of carbon additives, graphite and other organic compounds through solvation of solely lithium, iron, and phosphate compounds through addition of sulfuric acid; (c) precipitation of iron phosphate by addition of hydrogen peroxide; (d) extraction of lithium phosphate from the mother liquor; (e) recycling of mother liquor into water and sodium sulfate. This process wastes few chemicals while still having a high reclamation efficiency in terms of purity and quantity. Furthermore, due to its relatively low costs, the profit margin of this process is very good.

Abstract: The invention discloses a method for synthesizing a lithium ferromanganese phosphate composite material. The method produces a lithium ferromanganese phosphate composite material and resolves prior art issues of low molecular surface area and easy water absorption of the product. Furthermore, it minimizes prior method's difficult or expensive steps and lack of flexible control of the iron to manganese ratio within the lithium ferromanganese phosphate compound. In this method, many milling and sintering steps are taken to increase the compound's molecular surface area. Furthermore, selected carbon additives resolve the low conductivity brought about by low molecular surface area. As well, a hydrophobic material is coated on the surface of lithium ferromanganese phosphate to insulate it from outside moisture.

Abstract: The invention discloses a lithium ferromanganese phosphate composite material and a preparation method thereof. The lithium ferromanganese phosphate composite material prepared comprises lithium ferromanganese phosphate material, additive carbon, and a hydrophobic material coating on the surface of the lithium ferromanganese phosphate. Since the hydrophobic material is coated on the surface of lithium ferromanganese phosphate, the lithium ferromanganese phosphate is insulated from outside moisture. Therefore, compared to traditional lithium ferromanganese phosphate material, this lithium ferromanganese phosphate composite material does not easily absorb water within a lithium ferromanganese phosphate battery.

Abstract: This method prepares high performance lithium iron phosphate nanopowder, used in the construction of cathode material for lithium ion batteries. The preparation comprises the following steps: (a) the synthesis of iron hydrogen phosphate (FeHPO4) by mixing high purity nano-size metal iron powder (Fe) and phosphoric acid (H3PO4) in solution, (b) addition of a water-soluble lithium source and carbon source to the previous solution to yield a slurry (M?1), and (c) the (M?1) slurry being milled, spray dried, heat treated, and magnetically filtered to obtain a lithium iron phosphate nanopowder. The preparation method is simple, has low cost, and produces a high performance lithium iron phosphate nanopowder with high purity, high conductivity, cycling stability, and comprehensive electrochemical performance.

Abstract: This method synthesizes low-cost, high-performance iron phosphate that can be used for producing lithium-ion battery cathodes. It has three main steps: (S1) the synthesis of a iron (II,III) phosphate solution by mixing waste iron oxide (FeO, Fe2O3), low purity iron powder, and sulfuric acid in an aqueous solvent, followed by the addition of phosphoric acid; (S2) the addition of hydrogen peroxide to the previous solution, followed by pH balancing chemicals to yield crude iron phosphate; and (S3) the stirring of the previous solution to precipitate iron (III) phosphate, followed by an aging step, a filtering step, a washing step, and a drying step to obtain iron phosphate, which may be in the form of a hydrate. This straightforward approach uses waste iron oxide to minimize costs, while still yielding a fairly pure iron phosphate with excellent capacity, cycling stability, and broad physical and chemical properties suitable for battery production.

Abstract: This method recycles lithium iron phosphate batteries to extract cathode active materials, anode active materials, current collector metals, electrolyte, and separator materials in a highly pure state. The process involves the discharging and subsequent disassembly of used batteries into individual components—anode and cathode electrodes, electrolyte, separator, tape, and tabs, achieved via a brine bath, a dimethyl carbonate bath, and physical dismounting. Anode and cathode materials are then separated from their respective current collectors using specific solvent-cosolvent combinations, followed by purification procedures involving washing, heat treatment, and additional purification steps for the cathode. The process results in the extraction of highly pure battery materials including active anode and cathode materials, current collector metals, electrolyte, and separators.
