Abstract
A method of attaching a battery cell in an apparatus acted upon by centrifugal force avoids an extreme decline in discharge capacity of the battery cell when acted upon by the centrifugal force. The battery, of the type including a positive polarity material and a negative polarity material which are placed in opposition in a thickness direction of a battery case with an intervening separator disposed therebetween, and a liquid electrolyte packed inside the battery case, is mounted in the apparatus, oriented such that a negative polarity material side of the battery cell faces generally in a direction in which the centrifugal force acts on the apparatus, and an angle of inclination of a thickness direction of the battery cell is within a range of 0 to about 60 degrees relative to the direction of the centrifugal force.
