摘要： This invention provides an electrolyte injection apparatus capable of injecting an electrolyte accurately into a battery which does not contain an electrolyte yet and in which an electrode group consisting of a laminated structure formed by interposing a separator between positive and negative electrodes is accommodated in a case such that a lamination plane of the electrode group is parallel to the direction of depth of the case. The electrolyte injection apparatus of this invention includes a rotary table, an electrolyte injection member supported by the rotary table so as to be tilted by a centrifugal force upon rotation of the rotary table, and the injection member further having an internal hole whose bottom section is tapered, and a small-diameter exit hole formed in a lower end thereof and communicating with the internal hole, a holding mechanism for holding the battery containing no electrolyte below the injection member such that the exit hole of the injection member is inserted into an opening portion of the case with a desired distance held between a lower opening portion of the exit hole and an upper end of the electrode group, and an electrolyte supply mechanism for supplying an electrolyte to the injection member.
