Abstract
Disclosed are a lithium battery and methods for the manufacture thereof. Such a lithium battery includes a stack of a negative electrode, a separator, and a positive electrode. In the manufacturing methods, a pattern of holes is produced in the negative electrode as well as in the positive electrode, and a polymeric material is caused to penetrate the holes, whereby the negative electrode, the positive electrode and the separator are stuck and pressed together. Moreover, the negative electrode and the positive electrode are provided with an alignment pattern which can be used for the purpose of aligning the electrodes. The presence of such an alignment pattern facilitates the alignment of the layers with respect to each other.
