Technical details and manufacturing context for Electrode Assembly

Definition
The electrode assembly is a core structural and functional element of a solid-state cell module, consisting of anode and cathode layers separated by a solid electrolyte. It enables the storage and release of electrical energy through reversible electrochemical reactions, with the solid-state design offering enhanced safety, energy density, and thermal stability compared to liquid electrolyte systems.
Working Principle
During charging, lithium ions migrate from the cathode through the solid electrolyte to the anode, where they are stored. During discharging, ions move back to the cathode, releasing electrons that flow through an external circuit to power devices. The solid electrolyte prevents dendrite formation and thermal runaway.
Common Materials
Lithium metal or graphite (anode), Lithium transition metal oxide (cathode), Ceramic or polymer solid electrolyte, Current collectors (copper/aluminum foil)
Technical Parameters
  • Thickness of electrode layers and overall assembly (mm) Standard Spec
Components / BOM
  • Anode Layer
    Stores lithium ions during charging and releases them during discharging
    Material: Lithium metal or graphite composite
  • Cathode Layer
    Provides lithium ions during charging and accepts them during discharging
    Material: Lithium transition metal oxide (e.g., NMC, LFP)
  • Solid Electrolyte Separator
    Conducts lithium ions while preventing electrical short circuits
    Material: Ceramic (e.g., LLZO) or polymer electrolyte
  • Current Collectors
    Provide electrical connection to external circuit
    Material: Copper foil (anode), Aluminum foil (cathode)
Engineering Reasoning
0.1-4.2 V potential difference across electrode interfaces
Lithium plating initiates at 0 V vs Li/Li⁺ reference potential with current density exceeding 1 mA/cm²
Design Rationale: Lithium dendrite formation due to uneven current distribution exceeding Sand's time threshold (τ = πD(C₀/2j)² where D=10⁻¹⁰ cm²/s, C₀=1 mol/L, j>1 mA/cm²)
Risk Mitigation (FMEA)
Trigger Local current density exceeding 2 mA/cm² at electrode-electrolyte interface
Mode: Metallic lithium plating and dendritic growth penetrating separator
Strategy: Gradient porosity electrode design with 15-35 μm pore size distribution and 3-layer composite separator (PE/PP/PE)
Trigger Electrode particle fracture from >0.5% lattice volume change during lithium intercalation
Mode: Active material isolation and solid electrolyte interface layer rupture
Strategy: Core-shell NMC811 particles with Li₂MnO₃ coating and 2% Al doping to maintain α-NaFeO₂ structure
