Abstract
An electrochemical cell (10) including a positive electrode (20), a negative electrode (30) and a low temperature organic, liquid lithium salt electrolyte (40) is provided. The low temperature lithium salt electrolyte includes a central atom selected from the group of aluminum, boron, gallium, indium, or thallium and at least four substituent groups which are organic, alkoxy groups. A unique characteristic of the electrolyte is that it remains liquid at ambient temperatures, as compared to most lithium salt electrolytes which are solid at room temperatures.
Claims
1. A low temperature molten lithium salt electrolyte
comprising a group III A anion center having a negative charge wherein said anion is boron and at least four organic alkoxy ligands arranged around said anion center.
2. An electrochemical cell comprising:
an anode;
a cathode; and
a low temperature liquid organic lithium salt electrolyte having the formula
Mx+ [(ZR1, Z'R2, Z"R3 Z"'R4) A-]x
where M is a group IA or IIA metal; A is a group III A element; Z, Z', Z", and Z"' are each selected from the group of S, or O; R1, R2, R3, and R4 are each an organic group of up to 20 carbons and x is 1 or 2.
3. An electrochemical cell as in claim 2, wherein R1, R2, R3, and R4 are the same.
4. An electrochemical cell as in claim 2, wherein at least one of R1, R2, R3, and R4 is different than the others.
5. An electrochemical cell as in claim 2, wherein R1, R2, R3 and R4 are each selected from the group of substituted or unsubstituted alkoxy groups having up to 20 carbons.
6. An electrochemical cell as in claim 2, wherein M+ is lithium.
7. An electrochemical cell as in claim 2, wherein A- is
aluminum.
8. An electrochemical cell as in claim 2, wherein each of ZR1, Z'R2, Z"R3, Z"'R4) is 2-methoxyethoxy.
9. An electrochemical cell as in claim 2, wherein said electrolyte is lithium tetrakis [2-methoxyethoxy] aluminate.
