  • Patent number: 8394291
    Abstract: Processes produce a lithium vanadium fluorophosphate or a carbon-containing lithium vanadium fluorophosphate. Such processes include forming a solution-suspension of precursors having V5+ that is to be reduced to V3+. The solution-suspension is heated in an inert environment to drive synthesis of LiVPO4F such that carbon-residue-forming material is also oxidized to precipitate in and on the LiVPO4F forming carbon-containing LiVPO4F or CLVPF. Liquids are separated from solids and a resulting dry powder is heated to a second higher temperature to drive crystallization of a product. The product includes carbon for conductivity, is created with low cost precursors, and retains a small particle size without need for milling or other processing to reduce the product to a particle size suitable for use in batteries. Furthermore, the process does not rely on addition of carbon black, graphite or other form of carbon to provide the conductivity required for use in batteries.

  • Patent number: 8343388
    Abstract: Disclosed are an electrode having a porous active coating layer, a manufacturing method thereof and an electrochemical device containing the same. The electrode having a porous active coating layer according to the present invention may be useful to enhance peeling and scratch resistances of the porous active layer and improve a lamination characteristic toward the porous active layer by introducing a porous active layer onto a porous substrate having pores, the porous active layer having heterogeneity of morphology toward a thickness direction in which a content ratio of the binder polymer/inorganic particles present in a surface layer is higher than that of the binder polymer/inorganic particles present inside the surface layer. Accordingly, the stability and performances of the battery can be improved at the same time since the detachment of the inorganic particles from the porous active layer may be reduced during the assembly process of the electrochemical device.
