The copper mesh current collector with rhombic pores is a 3D structural substrate used primarily in high-power lithium-ion batteries and next-generation lithium-metal anodes.
The mesh design provides a "bridge-and-void" architecture that offers specific advantages over both solid and standard perforated foils:
(1) 3D Skeleton: The mesh pattern creates a three-dimensional framework that allows the active anode material (like graphite or silicon) to be embedded inside the mesh rather than just coated on top.
(2) High Opening Ratio: These meshes typically have a high "open area" (often 40%–70%), which drastically reduces the amount of inactive metal in the battery.
(3) Interlocking Diamonds: The geometry of the meshed openings provides superior mechanical interlocking, which is critical for preventing the electrode material from falling off during high-vibration use or rapid expansion.
Therefore, it brings the following advantages: (1) Volume expansion accommodation; (2) Enhanced ion pathways; (3) Heat dissipation; (4) Dendrite suppression.
