Abstract
Official abstract text for this publication.
An electrolyte composition and a sodium secondary battery are provided. The electrolyte composition includes an alcohol compound and a metallic salt, wherein the metallic salt consists of a sodium salt formed. The sodium secondary battery includes the electrolyte composition, a positive electrode, a negative electrode, and a separator disposed between the positive electrode and the negative electrode.
First claim
Opening claim text (preview).
What is claimed is: 1 . An electrolyte composition, comprising: an alcohol compound; and a metallic salt, wherein the metallic salt consists of a sodium salt. 2 . The electrolyte composition as claimed in claim 1 , wherein the alcohol compound comprises mono-alcohol, diol, triol, or a combination thereof. 3 . The electrolyte composition as claimed in claim 2 , wherein the mono-alcohol comprises ethanol. 4 . The electrolyte composition as claimed in claim 2 , wherein the diol comprises diethylene glycol, triethylene glycol, tetraethylene glycol, ethylene glycol, 1,3-propanediol, 1,4-butanediol, 1,5-pentanediol, or a combination thereof. 5 . The electrolyte composition as claimed in claim 2 , wherein the triol comprises glycerol. 6 . The electrolyte composition as claimed in claim 1 , wherein the sodium salt comprises NaPF 6 , NaBF 4 , NaClO 4 , NaBr, NaCl, or a combination thereof. 7 . The electrolyte composition as claimed in claim 1 , wherein the sodium salt comprises NaHCO 3 , NaNO 3 , CH 3 COONa, C 6 H 4 (OH)COONa, or a combination thereof. 8 . The electrolyte composition as claimed in claim 1 , wherein the molar ratio of alcohol compound to the sodium salt is between 3:1 and 48:1. 9 . A sodium secondary battery, comprising: a positive electrode; a negative electrode; a separator, disposed between the positive electrode and the negative electrode; and the electrolyte composition as claimed in claim 1 . 10 . The sodium secondary battery as claimed in claim 9 , wherein the positive electrode comprises sodium-containing oxide, sodium-containing ferrocyanide, or sodium phosphate. 11 . The sodium secondary battery as claimed in claim 9 , wherein the negative electrode comprises metal oxide, or sodium phosphate. 12 . The sodium secondary battery as claimed in claim 9 , wherein the separator comprises glass fiber film, filter paper, polypropylene polymer film, polyethylene polymer film, or a combination thereof.
