Lithium Battery Materials

Lithium Battery Materials for Manufacturing and R&D

This category brings together separator solutions, ceramic coating powders, glass fiber insulation, and process additives that help improve safety, consistency, and throughput in cells and packs. Backed by 20+ years of materials expertise, certified quality systems, and a reliable supply chain, we make one‑stop sourcing straightforward for diverse Li‑ion applications.

Separator and Coating Solutions

Coating‑grade nanosilica and specialty separator substrates enhance wetting, thermal stability, and mechanical strength. These materials support uniform coatings and stable, high‑yield production.

Nanosilica (SiO2, 20–30 nm) for Ceramic‑Coated Films

• Primary particle size: 20–30 nm for fine, uniform ceramic layers.

• Morphology designed to maintain porosity and reduce pore blockage.

• Good dispersion with low agglomeration for stable slurries.

Benefits include improved thermal resistance, puncture strength, and electrolyte wettability on PP/PE separators. Consistent supply and batch control support scale‑up from pilot to mass production.

Hydrophilic Separator Substrates

Hydrophilic options enable fast wetting and stable ionic pathways, especially in water‑based or research‑driven systems. Available in roll and sheet formats with stable pore structures to reduce initial impedance.

Electrode Slurry and Process Additives

Nano SiO2 as a Rheology Modifier

As a thixotropic agent, nanosilica helps control viscosity in NMP or water‑based slurries. It limits sedimentation of active and conductive particles, supports uniform coating thickness, and reduces micro‑defects on high‑speed lines.

Sodium Sulfate 99.8% (Battery‑Grade)

High‑purity sodium sulfate supports precursor processing, washing, and calibration in pilot or lab workflows. Consistent quality reduces variability and helps maintain repeatable outcomes.

Assembly Insulation and Safety Components

Glass Fiber Insulation and Barriers

Glass fiber materials offer thermal insulation, dielectric strength, and dimensional stability. Use them for module spacers, pack barriers, and fire‑resistant layers to limit heat propagation and protect sensitive components.

Vents and Safety Hardware

Venting solutions for enclosures and modules provide pressure relief with consistent opening behavior, supporting system protection under abnormal conditions.

Quality, Testing, and Documentation

Operations follow ISO9001, ISO14001, ISO45001, and ISO17025 frameworks. These systems support batch‑to‑batch consistency, environmental stewardship, workplace safety, and reliable testing. Each shipment includes specifications and lot traceability to simplify incoming inspection and speed qualification.

Custom Formats and Technical Support

Choose roll or cut formats, surface options, and packaging aligned with coating and assembly equipment. Flexible MOQs and coordinated delivery help match production schedules. Rapid sampling, dispersion tips, and handling guidance for nano powders and insulation support trials and scale‑up.

Applications

• EV battery packs

• Stationary energy storage systems

• Power tools

• Micromobility

• Consumer electronics

Materials are selected for safety, consistency, and manufacturability across common chemistries and formats.

FAQ

When should I use a hydrophilic separator?

Use it when fast wetting and low initial impedance are critical, especially with water‑based systems or specialty chemistries.

How do I choose SiO2 (20–30 nm) for ceramic‑coated separators?

Match particle size and dispersion behavior to your substrate, target porosity, and slurry system. We provide dispersion guidance and sampling for trials.

Can formats and deliveries be customized?

Yes. We support roll width, cut size, surface treatments, packaging options, flexible MOQs, and documented lot traceability.
