This standard replaces the standard previously issued as follows. - HG/T 4066-2008. Lithium hexafluorophosphate WARNING. Lithium hexafluorophosphate absorbs moisture very easily, to generate hydrofluoric acid, which is highly corrosive. Some of the reagents used are toxic or corrosive, so wear protective equipment and operate in a fume hood! If splashed on the eyes or skin, immediately flush with water for more than 15 minutes and seek medical treatment immediately. When using flammable materials, it is strictly forbidden to use an open flame for heating.1 ScopeThis standard specifies the requirements, test methods, inspection rules, marking, labeling, packaging, transportation, storage for lithium hexafluorophosphate. This standard applies to lithium hexafluorophosphate. This product is used for the electrolyte salt of lithium ion battery electrolyte and lithium ion supercapacitor electrolyte.2 Normative referencesThe following documents are essential to the application of this document.
