NONAQUEOUS ELECTROLYTE SECONDARY BATTERY AND METHOD FOR MANUFACTURING NONAQUEOUS ELECTROLYTE SECONDARY BATTERY |
摘要 |
A nonaqueous electrolyte secondary battery of the present invention has a positive electrode charge potential of 3.7 V or less with respect to a lithium metal potential, and includes a sulfuric acid ester having a specific structure in the nonaqueous electrolyte in an amount of 0.1 to 4.0% by mass based on the total mass of the nonaqueous electrolyte. Consequently, generation of gas in the battery associated with decomposition of an electrolyte solution when the battery is used under a high-temperature environment for a long period of time can be suppressed, so that expansion of the battery associated with long-term usage is hard to occur. |
