Title:
電極シートの製造方法
Document Type and Number:
Japanese Patent JP7268081
Kind Code:
B2
Abstract:
A method for producing an electrode sheet includes roll-pressing an uncompressed electrode sheet including a current collecting foil and an uncompressed electrode layer formed thereon and made from composite particles including active material particles and binder particles, by feeding the uncompressed electrode sheet to pass through a gap between first and second rolls to compress, and heating the sheet so that the active material particles are bonded to each other and also to the current collecting foil. A first outer peripheral surface temperature of the first roll contacting the foil falls within a temperature range from a binder-resin melting start temperature +5° C. to +25° C., and a second outer peripheral surface temperature of the second roll contacting the uncompressed electrode layer is lower than the first outer peripheral surface temperature and further falls within a temperature range not exceeding the melting start temperature +5° C.
