Abstract

PURPOSE:To obtain the practically satisfied cycle characteristic, and to increase the discharge capacity in comparison with graphite to reduce the frequency of charge by using compound oxide of tin and specified metal as the negative electrode material. CONSTITUTION:Compound oxide of tin and specified metal, which has the layered crystal structure and in which metal ion such as lithium ion intrudes between the layers to form the layer-to-layer compound at the time of charge, is used for the negative electrode material. Namely, compound oxide of tin (Sn) and lithium (Li), titanium(Ti), zirconium(Zr), Vanadium(V), niobium(Nb) or the like is used for the negative electrode material, which can store and discharge alkali metal ion such as lithium ion or the like. Since the compound oxide of tin and a specified metal, which can store and discharge a large quantity of lithium ion or the like and in which a collapse of the crystal structure due to the repetition of charge and discharge is hard to be generated, is used for the negative electrode material, practically satisfied cycle characteristic is obtained, and the discharge capacity can be increased.

2. Description of the Related Art In recent years,
The reason why a non-aqueous electrolyte secondary battery does not need to consider the decomposition voltage of water unlike an aqueous secondary battery that uses a water-containing electrolyte such as a nickel-cadmium secondary battery is that a high voltage design is possible. Since then, it is in the spotlight.

Conventionally, as a negative electrode material of this type of battery,
Metallic materials such as metallic lithium were used, but recently
The problem of internal short-circuiting due to the growth of dendritic electrodeposited lithium has been pointed out, and there is no such problem. Metals such as iron oxide and molybdenum oxide, which only occlude and release metal ions during charge and discharge, are not present. Oxides and graphite are being considered as new materials to replace the conventional metallic lithium. Of these, metal oxides such as iron oxide and molybdenum oxide are excellent in high rate discharge characteristics because of high internal diffusion rate of ions, while graphite is excellent in cycle characteristics.
