NON-AQUEOUS ELECTROLYTE SECONDARY CELL AND DEVICE USING THE SAME

摘要

In a rechargeable non-aqueous electrolyte secondary battery containing positive electrodes, negative electrodes and a non-aqueous solvent, an organic compound having a HOMO energy of -8.5 eV to -11.0 eV and a LUMO energy of -0.135 eV to 3.5 eV which are calculated using PM3 method for Hamiltonian in semiempirical molecular orbital calculation method is added to the non-aqueous solvent. According to the present invention, batteries excellent in safety and long-term reliability and portable information devices are provided.
