Provided are a crystalline iron phosphate doped with metals (MFePO 4 ), which is used as a precursor of olivine-structured LiMFePO 4 (LMFP) used as a cathode active material for lithium secondary batteries, and a method of preparing the crystalline iron ph...

Producing a first particulate hybrid material in a negative electrode of lithium batteries and -accumulators, comprises (a) mixing a water- or alcohol-soluble titanium compound, at least one acetate compound or ion M, an organic diol, lithium hydroxide, at...

Disclosed is a method for producing a lithium difluorobis(oxalato)phosphate solution, which is characterized by that lithium hexafluorophosphate and oxalic acid are mixed together in a nonaqueous solvent, in a manner that the molar ratio of lithium hexaflu...
