Title:
ELECTRICITY STORAGE DEVICE MANUFACTURING METHOD AND DOPING BATH
Document Type and Number:
WIPO Patent Application WO/2014/097906
Kind Code:
A1
Abstract:
Provided is an electricity storage device manufacturing method capable of reducing manufacturing process steps requiring a dry environment in comparison with the prior art, and also provided is a doping bath suitable for this manufacturing method.
The electricity storage device manufacturing method has a cell preparation step and a pre-doping step. The cell preparation step prepares an electricity storage cell (1) having: an assembled electrode (10) having a separator (103) interposed between a positive electrode (101) and a negative electrode (102); an outer package body (11) housing the assembled electrode (10); and an electrolyte (12) filled in the outer package body (11). The pre-doping step allows, after the cell preparation step, the electrolyte (12) in the outer package body (11) to communicate with another electrolyte (21) in a bath (20) of a doping bath (2) having, in the bath (20), a lithium electrode (22) immersed in the electrolyte (21) to form a liquid communicating state. The pre-doping step also allows the lithium electrode (22) to be electrically connected to the positive electrode (101) or the negative electrode (102), supplies lithium-ions generated at the lithium electrode (22) into the outer package body (11) via an electrolyte (210) forming the liquid communication state, and dopes lithium into the positive electrode (101) or the negative electrode (102).
