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the detection timing, the shutter is withdrawn to open the flowing path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.
