  • Patent number: 9865875
    Abstract: The present invention relates to a method for preparing a lithium iron phosphate nanopowder, including the steps of (a) preparing a mixture solution by adding a lithium precursor, an iron precursor and a phosphorus precursor in a glycerol solvent, and (b) putting the mixture solution into a reactor and heating to prepare the lithium iron phosphate nanopowder under pressure conditions of 1 bar to 10 bar, and a lithium iron phosphate nanopowder prepared by the method. When compared to a common hydrothermal synthesis method, a supercritical hydrothermal synthesis method and a glycothermal synthesis method, a reaction may be performed under a relatively lower pressure. Thus, a high temperature/high pressure reactor is not necessary and process safety and economic feasibility may be secured. In addition, a lithium iron phosphate nanopowder having uniform particle size and effectively controlled particle size distribution may be easily prepared.

    Abstract: A process for producing a separator-electrolyte layer for use in a lithium battery, comprising: (a) providing a porous separator; (b) providing a quasi-solid electrolyte containing a lithium salt dissolved in a first liquid solvent up to a first concentration no less than 3 M; and (c) coating or impregnating the separator with the electrolyte to obtain the separator-electrolyte layer with a final concentration ?the first concentration so that the electrolyte exhibits a vapor pressure less than 0.01 kPa when measured at 20° C., a vapor pressure less than 60% of that of the first liquid solvent alone, a flash point at least 20 degrees Celsius higher than a flash point of the first liquid solvent alone, a flash point higher than 150° C., or no detectable flash point. A battery using such a separator-electrolyte is non-flammable and safe, has a long cycle life, high capacity, and high energy density.

  • Patent number: 8859145
    Abstract: A primary cell having an anode comprising lithium or lithium alloy and a cathode comprising iron disulfide (FeS2) or a mixture of iron disulfide (FeS2) and iron sulfide (FeS) and conductive carbon particles. A cathode slurry is prepared comprising the FeS2 or FeS2 plus FeS powder, conductive carbon, binder, and a solvent. The binder is preferably a styrene-ethylene/butylene-styrene (SEBS) block copolymer. There is an advantage discovered in utilizing a hydronaphthalene solvent to form the cathode slurry. The preferred solvent is 1,2,3,4-tetrahydronaphthalene or decahydronaphthalene and mixtures thereof. The slurry mixture is coated onto a conductive substrate and the solvent evaporated leaving a dry cathode coating on the substrate. Higher drying temperature may be used resulting in a dry cathode coating which resists cracking. The anode and cathode can be spirally wound with separator therebetween and inserted into the cell casing with electrolyte then added.
