NEGATIVE ELECTRODE PLATE FOR NONAQUEOUS BATTERY, ELECTRODE GROUP FOR NONAQUEOUS BATTERY AND METHOD FOR PRODUCING SAME, AND TUBULAR NONAQUEOUS SECONDARY BATTERY AND METHOD FOR MANUFACTURING SAME

摘要

Disclosed is a negative electrode plate (3) for a nonaqueous battery, which comprises: a double side coated part (14) in which a negative electrode active material layer (13) is formed on the both surfaces of a collector core material (12); a core material exposed part (18) that is an end portion of the collector core material (12) on which the negative electrode active material layer (13) is not formed; and a single side coated part (17) which is positioned between the double side coated part (14) and the core material exposed part (18) and in which the negative electrode active material layer (13) is formed on one surface of the collector core material (12).  The both surfaces of the double side coated part (14) are provided with a plurality of grooves (10) which are inclined to the longitudinal direction of the negative electrode plate (3), while the single side coated part (17) is not provided with a groove (10).  A collector lead (20) of the negative electrode is connected to the core material exposed part (18).  The negative electrode plate (3) is rolled up in such a manner that the core material exposed part (18) makes the roll end.
