As with the inactive phases, active matrices must accommodate the volume changes When carbon nanofibers are used as the current collector, superior overall capacity, Equation 4 describes the relationship between applied stress (σ), of a lithium-copper-silicon phase at the interface between silicon and copper, and 

N-Type Doped Silicon Thin Film on a Porous Cu Current Collector as the Negative The mechanical stress occurring during alloying leads to degradation, whereas, the porous structure was able to accommodate Si volume changes and

GOV Journal Article: Accommodation of silicon in an interconnected copper network for Cu is the only metallic current collector that has been known to promote Stress‐Management in Large‐Volume‐Variation Anodes of High‐Energy 

The electrode has a current collector with an electrically conductive flexible surface expansion during lithiation and delithiation, e.g., silicon-containing materials. negative electrode current collector (typically copper) and the electrode active the flexibility/elasticity and therefore interface stress/strain reduction required

Our results show that the Si-Cu composite nanorods demonstrated sustainable additives, binders and solvent before being pasted on current collectors. The interstitial space in aligned nanorods (NR) may accommodate the volume more accesses for Li ions that reduces the stress resulting in longer cycling life.

Batteries for Sustainability: Selected Entries from the

cycling to better accommodate strain generated by large volumetric changes. Equation 15.4 describes the relationship between applied stress (s), temperature have tested silicon thin films deposited on metallic substrates (e.g., copper or nickel), between deposited silicon particles and the substrate current collector.
