NON-AQUEOUS ELECTROLYTIC SECONDARY BATTERY AND MANUFACTURING METHOD OF NON-AQUEOUS ELECTROLYTIC SECONDARY BATTERY |
摘要 |
A non-aqueous electrolytic secondary battery is provided having an electrode assembly having a positive electrode plate on which a positive electrode mixture layer is formed over a surface of a positive electrode core, and a negative electrode plate on which a negative electrode mixture layer is formed over a surface of a negative electrode core, and a non-aqueous electrolyte, wherein the positive electrode mixture layer includes a lithium transition metal complex oxide, the negative electrode mixture layer includes a negative electrode active material to and from which lithium ions may be introduced and extracted, a thickness of the positive electrode plate is less than or equal to 60 μm, a thickness of the negative electrode plate is less than or equal to 65 μm, a ratio of a thickness of the positive electrode core with respect to the thickness of the positive electrode plate is 22˜27%, and a ratio of a thickness of the negative electrode core with respect to the thickness of the negative electrode plate is 12˜15%. |
