Product Specifications

Technical details and manufacturing context for Solid Electrolyte Separator

Definition
A critical component within the electrode assembly that serves as both a physical barrier between anode and cathode and an ion-conducting medium, preventing electrical short circuits while enabling lithium-ion or other ion migration during charge/discharge cycles in solid-state batteries
Working Principle
Functions as an ion-conductive solid membrane that allows selective passage of lithium ions (or other charge carriers) while blocking electron flow, maintaining electrode separation to prevent internal short circuits and thermal runaway
Common Materials
Ceramic electrolytes (e.g., LLZO, LATP), Polymer-ceramic composites, Sulfide-based solid electrolytes
Technical Parameters
  • Thickness range typically 10-100μm, with thinner separators enabling higher energy density but requiring enhanced mechanical properties (μm) Per Request
Components / BOM
  • Electrolyte matrix
    Primary ion-conducting medium with crystalline or amorphous structure
    Material: Ceramic/polymer composite
  • Interface layer
    Enhances contact with electrode surfaces to reduce interfacial resistance
    Material: Functional coating materials
  • Support structure
    Provides mechanical integrity and dimensional stability
    Material: Polymer scaffold or reinforced matrix
Engineering Reasoning
0.1-100 MPa compressive stress, -40 to 200°C temperature, 1-1000 μm thickness
Fracture at 120 MPa compressive stress, ionic conductivity drops below 1×10⁻⁴ S/cm at 250°C, delamination at 50 MPa interfacial shear stress
Design Rationale: Brittle fracture exceeding fracture toughness (K_IC = 1.5 MPa·m¹/²), thermal decomposition of polymer-ceramic composite above glass transition temperature (T_g = 180°C), interfacial debonding due to coefficient of thermal expansion mismatch (ΔCTE = 8×10⁻⁶ K⁻¹)
Risk Mitigation (FMEA)
Trigger Lithium dendrite penetration exceeding separator mechanical strength (σ_yield = 80 MPa)
Mode: Internal short circuit with current surge > 10 C-rate
Strategy: Multilayer composite design with ceramic coating (Al₂O₃ layer, 5 μm) and polymer matrix (PVDF-HFP) for dendrite blocking
Trigger Cyclic volumetric expansion/contraction (ΔV = 12%) during charge-discharge causing fatigue
Mode: Crack propagation leading to ionic conductivity loss > 50% after 500 cycles
Strategy: Elastic polymer network (polyethylene oxide with 30% crosslinking) and compressive pre-stress (5 MPa) during cell assembly
