NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY |
摘要 |
A nonaqueous electrolyte secondary battery includes: an outer housing; a nonaqueous electrolyte filled in the outer housing, a positive electrode housed in the outer housing, a negative electrode housed in the outer housing and a separator disposed between the negative electrode and the positive electrode. The nonaqueous electrolyte comprises a nonaqueous solvent including diethyl carbonate and at least one of ethylene carbonate and propylene carbonate, and the nonaqueous electrolyte has a content of the diethyl carbonate of from 80 to 95% by volume. The positive electrode comprises a positive electrode active substance having a positive electrode potential in a full charged state of 4.4 V or higher with respect to a potential of metallic lithium. The negative electrode comprises a negative electrode active substance having a negative electrode potential in a full charged state of 1.0 V or higher with respect to a potential of metallic lithium. |
