ELECTRODE MATERIAL, METHOD OF MANUFACTURING THEREOF AND NONAQUEOUS LITHIUM SECONDARY BATTERY |
摘要 |
A crystal structure is provided to improve a characteristic of an electrode material, such as vanadium oxide. In the crystal structure, an amorphous state and a layered crystal state coexist at a predetermined ratio in a layered crystalline material such as vanadium oxide. In the layered crystalline material having such a layered crystal structure, layered crystal particles having a layer length L1 of 30 nm or shorter are formed. Ions are easily intercalated to and deintercalated from between the layers. When such a material is used for the positive electrode active material, a nonaqueous lithium secondary battery of which the discharge capacity and the cycle characteristic are good is manufactured.
