Abstract: PROBLEM TO BE SOLVED: To provide a secondary battery capable of improving cycle characteristics.
SOLUTION: An anode active material layer 22B is arranged on an anode collector 22A and an anode active material layer coating film 22C is provided on the anode active material layer 22B. The anode active material layer coating film 22C is composed of a barium compound, such as metal barium or barium oxide. Since the chemical stability of the anode 22 is enhanced, its reactivity is decreased. With this, a decomposition reaction of an electrolyte in charging/discharging is suppressed.

Abstract: PURPOSE:To make a job for teaching work performable so easily in a short time by statistically processing assembleable or unassembleable data at each position in the circumference of an assembly target point to be obtained at the time of searching and then performing a positional correction for the assembly target point. CONSTITUTION:A peripheral area 1 of an assembly target point P1 is searched by an assembling robot 5 on the basis of assembly target data of this assembly target point P1 through a specified searching method. Next, assembleable or unassembleable data D2 at each position in the circumference of the assembly target point P1 to be obtained in time of this searching are statiscally processed and thereby a positional correction for the assembly target point P1 is carried out. On the basis of this positionally corrected data D1, the assembling robot 5 is driven and controlled by a robot controller 4, thus the specified assembly operation is executed.
