A salt, in particular a lithium salt, that is usable in alkali metal cells and/or batteries, and/or electrolytes and/or additives for same is described. To achieve good ion conductivity as well as temperature and high voltage stability and to prevent corrosion of aluminum, for example a current collector, the salt includes at least one alkali metal ion and/or at least one ammonium compound and at least one anion that contains at least one unfluorinated (N,N-dialkylamide)sulfonyl group and/or at least one unfluorinated (N,N-dialkylamide)sulfoximide group, and at least one (perfluoroalkyl)sulfonyl group. An electrolyte, an additive, a cell, a battery, and a preparation method, are also described.

Disclosed are HPTS series derivatives and a synthesis method thereof, belonging to the field of organic synthesis. The HPTS series derivatives are prepared by introducing alkylamine or alcohol into sulfonic acid groups of HPTS. The synthesis method comprises the following steps: subjecting HPTS and phosphorus oxychloride to heating and reflux reaction for 12 hours under catalysis of DMF to obtain a reaction product; introducing the reaction product into ice water, stirring, precipitating solid, and performing suction filtration to obtain HPTS-SO.sub.2Cl; dissolving the HPTS-SO.sub.2Cl in tetrahydrofuran to prepare solution A, and dissolving alkylamine or alcohol in tetrahydrofuran to prepare solution B; mixing the solution A with the solution B and then reacting for 24 hours at normal temperature, obtaining a product by rotary evaporation, and obtaining a pure compound after separation through columns. The derivatives have strong fat solubility, overcome the defect of a very strong water solubility.
