Key Features
Advanced 4680 Cylindrical Tabless Design: 46mm diameter × 80mm height, tabless structure shortens current path by 95%, reduces internal resistance by 70-80%, and enhances heat dissipation efficiency by 600% compared to 2170 cells, ensuring stable high-power output.
High-Nickel NCM Cathode: Adopts high-nickel NCM ternary materials (e.g., NCM811 with 81.6% nickel content), cobalt-free formula reduces costs while boosting energy density and cycle life, balancing performance and sustainability.
Flexible Capacity Options: 78.4 kWh and 82 kWh standard versions, with support for higher capacity variants (82 kWh+), tailored to different range and performance needs of the 4th Gen Model Y (Rear-Wheel Drive/All-Wheel Drive variants).
Dry Electrode Technology: Solvent-free (NMP-free) manufacturing process simplifies production, reduces energy consumption by 50%, enables thicker electrode coatings, and increases energy density by 5% while lowering overall production costs.
Ultra-Fast Charging Capability: Compatible with Tesla Megacharger, supporting 4C fast charging (peak power up to 1.2MW), enabling 15 minutes of charging to replenish 50% power (about 420km WLTP range) and 30 minutes to reach 80% capacity.
Superior Cycle Life: ≥2000 charge-discharge cycles with ≥80% capacity retention, 33% longer than 2170 batteries, suitable for long-term vehicle ownership and heavy-duty use.
Enhanced Safety Performance: Equipped with silicon-composite anode (10% oxidized silicon with bionic carbon cage) to reduce volume expansion, self-healing separator, and potting process, passing full-charge needle puncture and collision tests without thermal runaway.
Seamless Compatibility: Fully adapted to the 4th Gen Tesla Model Y (2023–2026), matching CtC chassis integration, electrical specifications, and charging protocols, ensuring seamless assembly and optimal performance.
