<p>An apparatus (1) that supplies electrolyte inside a battery case disposed inside a reduced pressure chamber includes: a measuring unit (10) where a piston (12) moves in a first direction in a measuring space (S) inside a cylinder (11), a dispenser (20) that injects electrolyte from above into a battery case (200), a first pipeline (41) that connects an upper end portion of the measuring space (S) of the measuring unit (10) and the dispenser (20), and a back pressure valve (50) disposed on the first pipeline (41). The dispenser (20) includes a discharge nozzle (21) disposed inside the battery case (200) or in a periphery of an upper end of the battery case (200), a needle valve (23) that is disposed inside the discharge nozzle (21) and opens and closes the discharge nozzle (21), and an actuator (24) that drives the needle valve (23) up and down.</p> |
