Abstract
This invention provides a battery precursor for producing a battery through a cutting process, in which a large number of battery elements comprising positive active material layers, separators having electrolytes and negative active material layers are installed in parallel between a plate-like positive current collector plate and a negative current collector plate facing each other, and the respective battery elements are partitioned each other and sealed by insulators. According to this battery precursor, a battery having a voluntary shape can be obtained easily by cutting only.
