Abstract: The present technology relates to thiol functionalized conductors which can be grafted onto polymers and methods for making same. In certain embodiments, the thiol functionalized conductors can be grafted onto polymers with low Tg to synthesize single-ion conducting polymer electrolytes (SIPE) having improved conductivity. The thiol functionalized conductor compound comprises a covalently attached sulfonimide anion on one end, which is associated with a monovalent cation; 1-3 hydrocarbon chains as the linker (L); 0-2 functional groups (R); and a thiol group on the other end of the compound.

Abstract: The present technology relates to methods for the synthesis of a lithium single-ion monomer which comprises simultaneously reacting a sulfonyl chloride compound with i) a fluorinated sulfonamide compound and ii) a compound that is suitable to act as a quenching base and a lithium cation source. The simultaneous reaction of sulfonyl chloride with the fluorinated sulfonamide compound and the compound that is suitable to act as a quenching base and a lithium cation source yields the single-ion monomer.

Abstract: A lithium metal battery is disclosed. The lithium battery comprising a Li metal anode, a cathode and an electrolyte in between the Li metal anode and the cathode wherein the electrolyte includes immobilized anions at least at the interface between the Li metal anode and the electrolyte to maintain the anionic concentration at the interface above zero throughout the charge-discharge cycles thereby preventing surface potential instability at the interface of the Li metal anode and electrolyte.

Abstract: The present technology relates to laminates for lithium-ion batteries comprising at least one cathode layer; at least one anode layer; at least one electrolyte layer disposed between the at least one cathode layer and the at least one anode layer; and a viscosity modifier present on at least a portion of the laminate which limits the penetration of reactive fluids into the laminate and thereby controls the extent of oxidization of the anode, and prevents the formation of dendrites in said laminate. The present technology further relates to methods for preparing such laminates, and lithium-ion batteries comprising same.
