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 hexafluorophosphate to oxalic acid falls within a range of 1:1.90 to 1:2.10, and furthermore silicon tetrachloride is added to this, in a manner that the molar ratio of lithium hexafluorophosphate to silicon tetrachloride falls within a range of 1:0.95 to 1:1.10, thereby conducting a reaction. The lithium difluorobis(oxalato)phosphate solution produced by this method has low contents of chlorine compounds and free acids. Therefore, it can become an additive that is effective for improving performance of nonaqueous electrolyte batteries.

The invention relates to an article superior in making a waterdrop slip down a surface of the article. This article includes a substrate; and a functional film formed on a surface of the substrate. This functional film contains: (a) a silica forming a matrix of the functional film; (b) a silylated-terminal dimethyl silicone represented by the general formula [A], the dimethyl silicone being in an amount of from 0.1 wt % to 10 wt %, based on a total weight of the silica; and (c) a fluoroalkylsilane represented by the general formula [B]B(CF)CHCHSi(CH)(O&#xe00d;&#x2003;&#x2003;[B].
