Method and apparatus for manufacturing electrode assembly of secondary battery

An apparatus for manufacturing an electrode assembly of a secondary battery comprising:

• a positive electrode feeding device for outputting a positive electrode plate;
• a first separator feeding device for outputting a first separator;
• a first joining device arranged in the downstream of the positive electrode feeding device and the first separator feeding device, wherein the first joining device joins the positive electrode plate and the first separator to form a positive electrode composite plate body;
• a negative electrode feeding device for outputting a negative electrode plate;
• a second separator feeding device for outputting a second separator;
• a second joining device arranged in the downstream of the negative electrode feeding device and the second separator feeding device, wherein the second joining device joins the negative electrode plate and the second separator to form a negative electrode composite plate body;
• a winding device arranged in the downstream of the first joining device and the second joining device, wherein the winding device winds the positive electrode composite plate body and the negative electrode composite plate body to form an electrode assembly,
• wherein
• the apparatus further comprises a positive electrode plate cutter, the positive electrode plate cutter is arranged in the upstream of the first joining device, and the positive electrode plate cutter is configured for cutting off the positive electrode plate in the upstream of the joining position of the positive electrode plate and the first separator;
• and/or
• the apparatus further comprises a negative electrode plate cutter, the negative electrode plate cutter is arranged in the upstream of the second joining device, and the negative electrode plate cutter is configured for cutting off the negative electrode plate in the upstream of the joining position of the negative electrode plate and the second separator.
