In recent years, the new energy industry represented by photovoltaics and new energy vehicles has flourished, and the proportion of new energy consumption has been increasing year by year. In the field of photovoltaics, ultrafast laser technology is widely used in the manufacturing process of solar cells. For example, ultrafast lasers can be used for high-precision etching of thin film solar cells, such as narrow grooves in CIGSe and InSnOx, as well as etching of perovskite solar cells, to achieve efficient miniaturization of modules. In the field of lithium batteries, ultrafast laser technology also shows great potential. Ultra fast lasers can be used for laser cutting of electrode materials, avoiding problems such as burrs and curling caused by traditional mechanical cutting, thereby improving the safety and performance of batteries. In addition, ultrafast lasers can also be used for laser cutting of lithium battery lugs, solving the efficiency and flexibility problems of traditional hardware die-cutting technology, improving product stability and production cost-effectiveness.
