Document Type and Number:
Japanese Patent JP2007173150
Kind Code:
A
Abstract:
To provide a battery superior in high-temperature storage property by suppressing heat emission reaction at charging, which is characteristic of a nonaqueous electrolyte battery provided with a negative electrode that contains titanium oxide lithium as the negative electrode active substance.
By using LiB(C2O4)2, LiN(C2F5SO2)2 or LiN(CF3SO2)2 as an electrolyte salt, the nonaqueous electrolyte battery is obtained. Here 0.25 mol/liter or higher of these salts is preferably used. The salts may be used, mixed with LiPF6.
