NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY |
| 摘要 |
PURPOSE:To provide a secondary battery formed by using non-aqueous electrolyte and having an excellent cycle characteristic by using composite oxide made by partially replacing Li in material represented by chemical formula LiNiO2 with at least one of Na and K, for a positive electrode active material. CONSTITUTION:In a chemical formula LixMyO2 (wherein M is at least one of Na and K) a positive electrode including active material wherein values of x and y in the formula meet conditions of 0<x+y<=1.0 and 0<y<=0.3, a negative electrode using either of lithium, lithium alloy or carbon material into and from which lithium can be inserted and extracted respectively as an active material and non-aqueous material are used to construct a battery. By using such a positive electrode, a non-aqueous electrolyte secondary battery having good cycle time characteristic can be provided. |
