Key Features
Lithium Coil at 99.9% purity is lithium foil in a continuous spooled format, bringing the lowest-density metal in the periodic table — 0.534 g/cm³ — to roll-to-roll processing for battery electrode manufacture and prototype energy storage device assembly:
Lowest Density of Any Metal (0.534 g/cm³) for Lightweight Energy Storage
Lithium's density of 0.534 g/cm³ — the lowest of any metallic element — makes Lithium Coil a foundational material for lithium metal battery anode production and solid-state battery prototyping, where minimizing electrode mass directly improves energy density at the cell and pack level.
Uniform Thickness & Consistent Purity for Reproducible Electrochemical Characterization
Uniform thickness and consistent purity across the full coil length support reproducible electrochemical characterization — an essential requirement when studying lithium plating behavior, dendrite formation, and interface stability during cycling, where strip-to-strip material variation would confound experimental results.
Low Melting Point (180.5 °C) Requiring Controlled, Low-Moisture Handling
With an electrical resistivity of 9.29 µΩ·cm and a melting point of just 180.5 °C, Lithium Coil must be handled in controlled, low-moisture environments consistent with its high reactivity — a handling requirement that applies throughout coil storage, cutting, and electrode assembly operations.
Continuous Coil Format for Automated Cell Assembly Lines
The coil format is particularly suited to automated coin cell and pouch cell assembly lines, where consistent strip geometry across extended lengths directly affects cell-to-cell performance variation — supporting high-throughput, reproducible electrode fabrication for battery research and prototyping.
Reproducible Strip for Battery Performance & Safety Research
In research, Lithium Coil supports investigations into battery performance, cycle life, and safety improvements across reproducible, well-characterized strip lengths — providing a consistent lithium substrate for systematic experimental programs in energy storage research.
Industrial Applications
Lithium Coil is used across battery manufacturing, energy storage research, and electrode fabrication wherever a continuously processed, ultra-low-density lithium strip with consistent purity is required:
- ✦ Lithium Metal Battery Anode Production
- Used in lithium metal battery anode production, where the coil format supports continuous-feed electrode fabrication and lithium's position as the lowest-density metal in the periodic table directly contributes to the high gravimetric energy density that defines lithium metal battery chemistry.
- ✦ Solid-State Battery Prototyping
- Applied in solid-state battery prototyping, where Lithium Coil's consistent purity and uniform thickness across the coil length support reproducible cell-to-cell performance during the iterative prototyping cycles characteristic of solid-state battery development.
- ✦ Continuous-Feed Electrode Fabrication for Energy Storage Research
- Used for continuous-feed electrode fabrication in energy storage research, where the coil format's uninterrupted length enables automated cutting and forming of lithium electrodes at the throughput required for systematic battery performance and cycle life studies.
- ✦ Automated Coin Cell & Pouch Cell Assembly
- Used in automated coin cell and pouch cell assembly lines, where consistent strip geometry across extended coil lengths directly reduces cell-to-cell performance variation — a critical requirement for generating statistically meaningful battery test data across large sample sets.
- ✦ Battery Performance, Cycle Life & Safety Research
- Used in research to investigate battery performance, cycle life, and safety improvements across reproducible, well-characterized strip lengths — supporting systematic studies of lithium plating behavior, dendrite formation, and interface stability that depend on consistent starting material.
