Specifications vary by grade and production lot. Confirm the applicable COA or TDS, sampling method, and acceptance limits before cell qualification.

Use Cases

  • Lithium-metal pouch-cell and multilayer-cell development.
  • Anode-free and excess-lithium control experiments using a copper current collector.
  • Interface screening with liquid, polymer, sulfide, oxide, or halide solid-state electrolyte systems.
  • Final dimensions, surface protection, tab configuration, packaging, and shipping conditions should be confirmed by RFQ.

Technical Selection Guide

Why lithium foil on copper is used in cell development

Lithium metal laminated on a copper current collector provides a controlled lithium inventory and a current-collector geometry that is convenient for pouch-cell, multilayer, and interface experiments. A 50 um lithium layer on 10 um copper is thick enough for many excess-lithium studies while remaining closer to practical foil handling than bulk lithium chips.

Why developers evaluate it

  • Lithium-metal and anode-free architecture development
  • Liquid, polymer, and solid-state interface screening
  • Areal-capacity and lithium-inventory control studies

Development considerations

  • Confirm grade-specific particle size and surface condition
  • Match electrode loading and processing to the target cell
  • Use lot documentation and cell-level qualification

How to compare it

Surface condition, foil uniformity, edge quality, copper adhesion, protective packaging, and dry-room handling can materially affect reproducibility. Dimensions and lithium excess should be matched to cathode areal capacity.
