NON-AQUEOUS ELECTROLYTE SECONDARY CELL AND DEVICE USING THE SAME

摘要

A non-aqueous electrolyte secondary cell comprising an anode, a cathode and a non-aqueous solvent, which can be recharged, wherein the non-aqueous solvent contains 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, as calculated by using the PM3 method for Hamiltonian in semi-empirical molecular orbital method. The secondary cell is excellent in safety and the reliability for a long period of time, and can be used for manufacturing a portable information device having such advantages.
