NONAQUEOUS ELECTROLYTE SECONDARY CELL, POWER SUPPLY COMPRISING THE SECONDARY CELL, PORTABLE DEVICE, TRANSPORTABLE OR MOVABLE MACHINE, ELECTRIC APPARATUS FOR HOME USE, AND METHOD FOR CHARGING NONAQUEOUS ELECTROLYTE SECONDARY CELL

摘要

Non-aqueous electrolyte secondary cell contains positive and negative electrodes containing a material that stores and releases lithium ions and a binder polymer, separator(s) for separating the positive and negative electrodes, and a non-aqueous electrolyte containing a lithium salt and an organic solvent. Non-aqueous electrolyte secondary cell contains positive and negative electrodes containing a material that stores and releases lithium ions and a binder polymer, separator(s) for separating the positive and negative electrodes, and a non-aqueous electrolyte containing a lithium salt and an organic solvent. The electrolyte contains a substances which oxidizes at the positive electrode at an electric cell voltage of 4.1-5.2V. The substance is subjected to an oxidation reaction at the positive electrode which is different to the lithium releasing reaction and generates a reduction reaction different from the storing reaction at the negative electrode. Independent claims are also included for: (1) a power source where the cells are connected multiply, in series and/or in parallel; (2) a method of charging the cell.
