ORGANIC ELECTROLYTE SECONDARY BATTERY |
摘要 |
PURPOSE:To improve cycle life performance and lower internal resistance by forming organic solvent of a mixture of ethylene carbonate and 2-- methyldioxolan and specifying the content of 2-methyldioxolan in the organic solvent. CONSTITUTION:Organic solvent is formed of a mixture of ethylene carbonate and 2-methyldioxolan, and the content of 2-methyldioxolan in the organic solvent is 50V0L% or less. Ethylene carbonate (EC) and 2-methyldioxolan (2-MeD0L) are excellent in electrochemical stability. As a result, an organic electrolyte battery is obtained which has organic electrolyte with excellent anti-reducing performance and anti-oxidizing performance and still high conductivity and high lithium charging and discharging efficiency. |
