Wide Temperature Range: Operates reliably from -20℃ to 60℃, ideal for various climates.
High-Pressure Stability: Stable under 20MPa pressure conditions.
Long Cycle Life: Over 2,000 cycles at 1C charge/discharge at 45℃.
High-Temperature Storage: Maintains >93% capacity recovery after 28 days of full-charge storage at 60℃.
Power Performance: Supports 8C high-rate discharge for demanding applications.
Superior Safety: Passes extrusion and 200℃ hot box safety tests.

1. High-Nickel Positive Electrode with Dual-Layer Coating
Inner Coating: Boosts ion diffusion rate, stabilizes lattice, and inhibits oxygen release.
Outer Coating: Uses halide electrolyte to prevent side reactions with sulfide electrolyte, improving cycle stability.
2. Low-Expansion Silicon-Carbon Negative Electrode
3D Carbon Matrix Deposition reserves buffer space for silicon expansion.
Surface Carbon Coating reduces side reactions and enhances interface stability.
3. Dual-Layer Sulfide Electrolyte System
Cathode Side: Oxidation-resistant electrolyte prevents decomposition under high voltage.
Anode Side: Reduction-resistant electrolyte inhibits reaction with silicon-carbon anode.
Interface Optimization: Particle size control creates a mechanical interlocking effect, reducing impedance and boosting rate capability.
