“…The author, in a quest to uncover the theoretical intrinsic connection between texture and mechanical properties, takes a single face-centered cubic crystal cell as the focal point and attempts to calculate the Schmid factor size under various textures, aiming to delve into the impact of crystal orientation on mechanical properties. According to the mechanism of metal single crystal tensile deformation and the critical shear stress law, the Schmid factor (m) can be expressed as follows − m = cos nobreak0em0.25em⁡ φ nobreak0em0.1em⁡ cos nobreak0em0.25em⁡ λ In the equation, where m is the Schmid factor, φ is the angle between the normal direction of the slip plane and the tensile direction ( F ), and λ is the angle between the slip direction of the slip plane and the tensile direction. While eq indicates that m is related to the tensile direction, the actual tensile direction of ECF is generally unidirectional during the tensile test process.…”

Electrolytic copper foils (ECFs), owing to their excellent mechanical properties and conductivity, have become an indispensable component as an anodic current collector in lithiumion batteries. ECFs often show texture properties, but the intrinsic relationship between the texture and mechanical properties is rarely reported. The authors find a conspicuous preference for the (100) crystal plane in 6 and 8 μm ultrathin ECFs with high elongation. And certain ECFs even exhibit a positive correlation trend between elongation and the (100) relative texture coefficient. It can be inferred that enhancing the (100) texture contributes to the improvement of the elongation in ECFs. Moreover, the Schmid factor values for the ( 111), (100), and ( 110) planes are calculated. The results revealed that the number of slip systems that can be activated under different tensile directions of the (100) plane is the largest, while the number of (110) plane is the least. It implies that under equivalent conditions, ECFs with (100) plane orientation are more prone to undergo plastic deformation, thereby facilitating high elongation. In contrast, the (110) plane orientation contributes to a high tensile strength.
