| 摘要 |
The invention relates to an electrolyte for an electrochemical device. This electrolyte includes a first compound that is an ionic metal complex represented by the general formula (1). The electrolyte may further include at least one compound selected from second to sixth compounds respectively represented by the general formulas Aa+(PF6-)a, Aa+(ClO4-)a, Aa+(BF4-)a, Aa+(AsF6-)a, and Aa+(SbF6-)a, and special seventh to twelfth compounds. The electrolyte can be superior in heat resistance, hydrolysis resistance, cycle characteristics and shelf life as compared with conventional electrolytes.
