Title:
SECONDARY BATTERY PRODUCTION METHOD
Document Type and Number:
WIPO Patent Application WO/2018/155175
Kind Code:
A1
Abstract:
Provided is a secondary battery production method which is capable of more suitably coping with winding misalignment. The secondary battery production method according to the present invention is for producing a secondary battery having a wound electrode body comprising a positive electrode and a negative electrode, wherein the wound electrode body is formed by winding an electrode precursor laminated body comprising a laminate formed by stacking a positive electrode precursor and a negative electrode precursor with a separator interposed therebetween. During winding, the electrode precursor laminated body is subjected to pressing, and a pressure heater is used for that purpose.
