PURPOSE:To decrease self discharge of an aluminium-lithium alloy negative electrode and to obtain a negative electrode having high reliability by using an aluminium-lithium-indium alloy having a specified composition in a negative electrode. CONSTITUTION:An alloy comprising aluminium, lithium, and indium is used in a negative electrode. In this alloy, the ratio of the number of atom of aluminium to lithium is specified to 100:5-100:120, and that of aluminium to indium is specified to 100:1-100:100. By adding indium to the aluminium-lithium alloy of the negative electrode of organic electrolyte secondary battery, self discharge of the negative electrode can be retarded. |
