PURPOSE:To prevent voltage drop in an initial stage of high rate discharge by electrically connecting a higher resistance compared with a conventional discharge load resistance between a negative electrode and a positive electrode. CONSTITUTION:A negative electrode 2 such as lithium is press-bonded on the inner surface of a can 1 and a positive electrode obtained by press-bonding a porous carbon layer 4 on the outer side of a metal current collector 3 is arranged inside the negative electrode 2 with a separator 6 interposed. Electrolyte prepared by dissolving LiAlCl4 in SOCl2 is poured in the can to form a nonaqueous solvent battery. The negative electrode and positive electrode are electrically connected through a resistance 13 having high resistance value to flow extremely small amount of current. Thereby, LiCl film formed on the surface of the negative electrode 2 during storage is kept thin. Therefore, the LiCl film on the surface of the negative electrode is immediately broken in high rate discharge, and voltage drop is prevented and desired voltage is obtained from an initial stage of discharge. |
