METHOD OF MANUFACTURING A THIN LITHIUM BATTERY

摘要

Disclosed is a method of manufacturing a lithium battery having a stack of a negative electrode, a separator, and a positive electrode. A pattern of holes is produced in the negative electrode as well as in the positive electrode. A polymeric material is applied on at least one side of the stack and the stack is subjected to heat and pressure, so that the polymeric material penetrates the holes, whereby components are stuck and pressed together. The polymeric material includes bulges which are at least partially located at the ends of holes in the electrode (s). The provision of such bulges of polymeric material makes enough polymeric material available to fill the holes and stick together the electrodes and the separator, while on the outer sides of the stack, in between the holes, the polymeric material can be very thin or even be absent.
