High-performing 3M battery electrolyte salts have excellent thermal stability.      These products can be used in a variety of lithium batteries, including : - *Organic, electrolyte-based batteries - *Lithium ion cells - *Primary and secondary cells using organic liquid electrolytes - *Polymer batteries Please choose the product that is right for your application : - 3M™ Fluorad™ Fluorochemical Acid Salt FC-122 : Primary battery electrolyte salt - 3M™ Fluorad™ Battery Electrolyte FC-130 : Secondary lithium ion electrolyte salt - 3M™ Fluorad™ Battery Electrolyte HQ-115 : Primary and secondary lithium ion battery electrolyte salt   3M™ Fluorad™ Lithium Trifluoromethanesulfonate FC-122 is the lithium salt of trifluoromethane sulfonic acid, one of the strongest monoprotic organic acids known. Both Fluorad lithium trifluoromethanesulfonate FC-122 and the parent acid have exceptional thermal stability and are resistant to oxidation or reduction. Due to the unusual solubility characteristics and strong ionic nature of FC-122 lithium trifluoromethanesulfonate in aprotic organic solvents, solutions incorporating the product frequently exhibit low specific resistance, making them useful electrolytes in non-aqueous electrochemical cells. Lithium batteries have emerged as the battery type attracting significant commercial interest due to the wide variety of desirable performance features that can be obtained. The stability and low toxicity associated with FC-122 lithium trifluoromethanesulfonate make this lithium salt an excellent choice for use in primary lithium cells.   3M™ Fluorad lithium bisperfluoroethanesulfonimide (BETI) is an experimental salt developed for organic electrolyte-based lithium batteries. Evaluation of lithium bisperfluoroethanesulfonimide show that it does not corrode aluminum at high voltages. This is a major advancement over currently available 3M salt, Fluorad lithium trifluoromethanesulfonimide HQ0115. The new 3M salt offers manufacturers increased flexibility to develop better performing batteries.   3M™ Fluorad lithium (Bis) Trifluoromethanesulfonimide HQ-115 is an electrolyte salt ideal for organic electrolyte-based lithium batteries. Cyclic voltamogram studies indicate excellent electrochemical stability. The organic ion is capable of strong covalent bonding and hence exhibits excellent resistance to thermal degradation. Not only does the strong electron withdrawing power of the CF₃- groups help to delocalize the charge on the anion, but the presence of the sulfur, oxygen, and nitrogen atoms, can participate in charge dispersal to further promote dissociation. Fluorad battery electrolyte HQ-115 conductivity values similar to those of LiCIO₄and LiAsF6 are possible without the attendant stability and safety concerns. HQ-115 battery electrolyte has been evaluated in many emerging battery technologies with encouraging results. Papers have been published showing its utility in lithium ion cells, primary and secondary lithium cells using organic liquid electrolytes and polymer batteries.
