NONAQUEOUS ELECTROLYTE SOLUTION AND NONAQUEOUS ELECTROLYTE BATTERY |
摘要 |
Nonaqueous electrolytes capable of providing a battery having a high capacity and excellent in storability and cycle characteristics are provided. Also provided are nonaqueous-electrolyte batteries produced with the electrolytes. The nonaqueous electrolytes include ones which (1) contains a cyclic carbonate having an unsaturated bond and further contains a fluorinated cyclic carbonate having two or more fluorine atoms, (2) contains an aromatic compound having 7-18 carbon atoms in total and further contains a fluorinated cyclic carbonate having two or more fluorine atoms, (3) contains diethyl carbonate and further contains a fluorinated cyclic carbonate having two or more fluorine atoms, or (4) contains at least one compound selected from the group consisting of cyclic sulfonic acid ester compounds, di-sulfonic acid ester compounds, nitrile compounds, and compounds represented by general formula (1) and further contains a fluorinated cyclic carbonate having two or more fluorine atoms. The electrolytes further include (5) a nonaqueous electrolyte characterized by being an electrolytic solution for use in a high-voltage battery having a final charge voltage of 4.3 V or higher and containing a fluorinated cyclic carbonate having two or more fluorine atoms. |
