Ultra-Thin and High-Strength Series Lithium Battery Separator
The Ultra - Thin and High - Strength Series Lithium Battery Separator (models: SU02SS, SU03SS, SU05S, SU05SS) is developed by FSPG (Foshan Plastics Group Technology). It is a wet - processed PE - based separator, optimized for next - generation lithium - ion batteries. With advanced materials and manufacturing processes, this separator balances ultra - thinness, high mechanical strength, and excellent thermal stability, making it ideal for high - energy - density power batteries, energy storage systems, and high - end consumer electronics.
Product Advantages
Extreme Thinness & High Space Utilization:
The ultra - thin design maximizes space utilization in batteries, breaking through energy density limits to support longer driving ranges (for EVs) and longer device usage (for consumer electronics).
Dual Innovation (Material + Process):
By innovating both materials and production processes, we perfectly balance ultra - thinness and high strength, building a robust safety barrier against short circuits and thermal runaway.
Market - Leading Iteration:
As a leader in diaphragm technology, our product drives industry iteration—thinner, stronger, safer, and more efficient—empowering customers to create high - end battery cells for competitive markets.
Full - Scene Adaptability:
Customizable to meet the needs of power batteries (EVs), energy storage systems (grid, home), and high - end consumer electronics (smartphones laptops),, ensuring consistent performance across diverse applications.
Technical Parameters
Model: SU02SS, SU03SS, SU05S, SU05SS
Thickness: Ultra - thin (customizable range: e.g., 2μm - 5μm, subject to specific model)
Porosity: High porosity (typically 40% - 55%) for excellent electrolyte wettability and ion conductivity
Tensile Strength: High tensile strength (longitudinal: ≥150MPa; transverse: ≥50MPa, typical values) to resist mechanical stress during battery assembly and use
Thermal Stability: Stable up to 150°C (without coating) / 180°C (with ceramic coating, optional), preventing thermal shrinkage
Base Material: PE (Polyethylene) for inherent chemical stability and mechanical flbility
Product Application
Power Batteries:
Ideal for electric vehicles (EVs), hybrid electric vehicles (HEVs), and two - wheeled electric vehicles, where high energy density and safety are critical. The ultra - thin design boosts vehicle range, while high strength ensures durability during vibration and impact.
Energy Storage:
Suitable for grid - scale energy storage (ESS) and home energy storage systems. Its thermal stability and electrolyte compatibility enable long - cycle life (≥6000 cycles at 80% DOD), reducing maintenance costs.
Consumer Electronics:
Perfect for smartphones, laptops, tablets, and wearables. The thin, flexible design supports slim device profiles, while high safety prevents overheating or short circuits.
Product Usage Guide
Pre - processing:
Ensure the separator is stored in a dry, clean environment (relative humidity < 40%, temperature 20 - 25°C). Check for any visible damage before use.
Battery Assembly:
Align the separator between the positive and negative electrodes, ensuring no wrinkles or misalignment. Use automated equipment for precision placement to avoid mechanical damage.
Electrolyte Injection:
After cell formation, inject lithium - ion electrolyte (e.g., LiPF6 - based) following standard protocols. The separator’s high porosity will ensure rapid electrolyte absorption.
Testing & Quality Control:
Conduct voltage, capacity, and leakage current tests post - assembly. Monitor thermal stability via thermal runaway simulation (if required) to verify safety.
Product Certificates
Available certificates include ISO 9001 (Quality Management),
ISO 14001 (Environmental Management)

FAQ
Q1: Is the separator compatible with lithium - ion chemistries (NCM, LFP, etc.)?
A1: Yes, the PE - based separator is chemically stable and compatible with NCM, LFP, and other common lithium - ion battery chemistries. For specialized chemistries, we offer customized coating solutions (e.g., ceramic coating) to enhance compatibility.
Q2: How does the separator improve battery safety?
A2: Its high tensile strength prevents mechanical failure (e.g., tearing) during use, and thermal stability resists shrinkage at high temperatures, reducing the risk of internal short circuits. Optional ceramic coating further enhances thermal runaway protection.
Q3: What are the main application scenarios of the Ultra - Thin and High - Strength Series Separator?
A3: It is mainly used in high - energy - density power batteries, energy storage batteries, and high - end consumer electronics batteries. For example, in electric vehicles, energy storage power stations, and high - end mobile phones and laptops.
Q4: How does the separator balance ultra - thinness and high strength?
A4: Through the dual innovation of materials and processes, we have developed a unique formula and production process, which can make the separator have both ultra - thin thickness and high mechanical strength.
