The application of laser in lithium batteries

  The production process of lithium-ion battery modules for new energy vehicles can be divided into cell segment process and module segment(PACK segment)process,where the cell segment equipment can be further divided into front/middle segment and rear segment production processes.
  Laser equipment is widely used in the battery cell(mainly in the middle section)and PACK section.In the battery cell section,lithium battery equipment is mainly used in pole ear welding,sealing welding(sealing nails and top cover welding)and other links;PACK section,laser equipment is mainly used for the connection between battery cells.
  From the perspective of the value of lithium-ion equipment,in terms of automation level,the investment in lithium-ion equipment per GWh ranges from 400 million yuan to 1 billion yuan,with laser equipment accounting for a relatively high proportion of the total equipment investment.1GWh corresponds to a total investment of 60-70 million yuan in laser equipment,and the higher the degree of automation,the higher the proportion of laser equipment.
