Abstract: An electrolyte includes a composite salt mixture with a halogenated boron cluster salt. The halogenated boron cluster salt includes a cation selected from Li+, Na+, Mg2+, Ca2+, Zn2+ and Al3+, and a halogenated boron cluster anion. The halogenated boron cluster anion has a structure of [CB(y?1)H(y?z?i)RzXi]?, [C2B(y?2)H(y?t?j?1)RtXj]?, [C2B(y?3)H(y?t?j)RtXj]?, [C2B(y?3)H(y?t?j?1)RtXj]2?, or [C2B(y?4)H(y?t?j?1)RtXj]2?, [CB(y?1)H(y?z)Rz]?, [C2B(y?2)H(y?t?1)Rt]?, [C2B(y?3)H(y?t)Rt]?, [C2B(y?3)H(y?t?1)Rt]2?, and/or ByH(y?z?i)RzXi]2?, where y is an integer within a range of 6 to 12, (z+i) is an integer within a range of 0 to y, (t+j) is an integer within a range of 0 to (y?1), and X is F, Cl, Br, or I. Also, the composite salt mixture can be at least 90 mol % halogenated, for example, at least 90 mol % mono-halogenated or less than 10 mol % mono-halogenated.

Abstract: An electrolyte includes a composite salt mixture formed from a halogen-free closo-borate salt and a halogenated closo-borate salt. The halogen-free closo-borate salt includes a first cation selected from Li+, Na+, Mg2+, or Ca2+, and a closo-borate anion with the structure [ByH(y?z)Rz]2?, [CB(y?1)H(y?z)Rz]?, [C2B(y?2)H(y?t?1)Rt]?, [C2B(y?3)H(y?t)Rt]?, or [C2B(y?3)H(y?t?1)Rt]2?, and a second cation selected from Li+, Na+, Mg2+, or Ca2+,and a halogenated closo-borate anion with the structure [ByH(y?z?i)RzXi]2?, [CB(y?1)H(y?z?i)RzXi]?, [C2B(y?2)H(y?t?j?1)RtXj]?, [C2B(y?3)H(y?t?j)RtXj]?, or [C2B(y?3)H(y?t?j?1)RtXj]2?. The parameter y is an integer within a range of 6 to 12, z is an integer within a range of 0 to y, t is an integer within a range of 0 to (y?1), z+i is an integer within a range of 0 to y, t+j is an integer within a range of 0 to y?1, R is a linear, branched-chain, or cyclic C1-C18 alkyl or fluoroalkyl group, and X is F, Cl, Br, and/or I.
