High Purity 99.9% Lithium Chips Coin Cell Battery Materials

Product Overview

This high-purity lithium chip material is specifically engineered to serve as a premium anode standard for coin cell prototyping, half-cell characterization, and next-generation battery chemistry research. Fabricated with a certified purity exceeding 99.90% (typical values reaching 99.95%), this metallic lithium substrate delivers outstanding electrochemical stability and minimal internal resistance. By strictly controlling trace transition metals, alkali contaminants, and non-metallic inclusions, this product guarantees uniform current density distribution and reliable solid electrolyte interphase (SEI) film formation during early cycling stages.

Designed primarily for electrochemical laboratories, pilot-scale battery manufacturing lines, solid-state electrolyte development, and academic research institutions, this material provides exact dimensional integrity across standard button cell formats (such as CR2032, CR2025, and CR2016). Whether used for testing novel cathode formulations, evaluating advanced liquid or gel polymer electrolytes, or developing metallic lithium anode protection layers, this consumable ensures baseline reliability across repetitive test matrices.

Every production batch undergoes stringent inert atmosphere processing and multi-stage quality validation to eliminate surface oxidation, nitridation, and micro-defects. Packaged under ultra-pure argon within specialized hermetic containers, the material maintains its pristine metallic luster and ductile mechanical properties from manufacturing to glovebox unpacking. This rigorous control guarantees dependable reproducibility, eliminating experimental artifacts caused by substrate degradation or physical irregularities.

Key Features

• Ultra-High Chemical Purity (≥99.90% Li): Refined to meet and exceed national battery standards with typical lithium content of 99.95%, significantly reducing parasitic side reactions and extending cell cycle life during electrochemical evaluation.
• Stringently Controlled Trace Contaminants: Minimal allowable thresholds for hazardous impurities—including sodium (Na ≤ 0.02%), potassium (K ≤ 0.005%), calcium (Ca ≤ 0.02%), iron (Fe ≤ 0.005%), and nitrogen (N ≤ 0.02%)—mitigate uneven dendrite nucleation and catastrophic cell failure.
• Precision Dimensional Tolerances: Manufactured with strict diametrical accuracy (±0.02 mm) and tight thickness tolerances (down to ±0.01 mm), ensuring consistent mechanical stack pressure and perfect concentricity inside coin cell cases.
• Defect-Free Surface Morphology: Subjected to specialized rolling and precision stamping to yield a flat, lustrous finish completely free of pinholes, cracks, tears, oil residues, creases, or visible passivation layers.
• Clean, Burr-Free Edge Processing: Precision-sheared perimeter edges prevent localized electric field concentration, internal short-circuiting, and separator puncture during cell crimping procedures.
• Argon-Shielded Hermetic Packaging: Sealed in pre-dried metal canisters or aluminum-plastic composite pouches within an inert dry room environment, preventing ambient moisture or nitrogen contamination during transport and extended storage.
• Optimized Substrate Ductility: Retains ideal physical softness and mechanical malleability (density 0.534 g/cm³), enabling intimate interfacial contact with solid-state electrolytes, separator membranes, and current collectors.
