To provide a method of manufacturing a battery capable of providing an
equal amount of electrolyte in each battery and of enhancing productivity
and coating machines employed thereof. The sensor detects a boundary from
the collector exposed region C of the belt-shaped positive electrode to
the positive electrode mixture layer exposed region B, on the basis of the
detection timing, the shutter is withdrawn to open the flowing path and
the proportioning pomp is driven. Following this, when the sensor detected
a boundary from the positive electrode mixture layer exposed region B to a
collector exposed region C, and on the basis of the detection timing, the
shutter is protruded inside the flowing path to close the flowing path and
the proportioning pump stops. As a result of this, the electrolyte stops
to be delivered from the nozzle. The electrolyte layers are intermittently
formed by repeating the same procedures. With the proportioning pump, the
electrolyte is evenly applied to pressure in order to push the electrolyte
from the nozzle, so that a given amount of the electrolyte can be
delivered. Thereby, the electrolyte layers, which are thin and even in
thickness in width and longitudinal directions can be formed and an amount
of the electrolyte included in each of the batteries can be uniform.
