4680 Battery Pack for Tesla Model Y 4th Gen (2023–2026)

Product Overview

This 4680 cylindrical high-nickel NCM ternary lithium battery is exclusively developed for the 4th Generation Tesla Model Y (2023–2026), available in 78.4 kWh, 82 kWh, and higher capacity variants (82 kWh+). Integrating Tesla’s cutting-edge technologies—including tabless cell structure, dry electrode manufacturing, and high-nickel NCM cathode materials (Ni>88%)—it achieves a significant breakthrough in energy density, charging speed, and structural integration compared to traditional 2170 batteries. Fully compatible with the 4th Gen Model Y’s Cell-to-Chassis (CtC) integration design, advanced powertrain, and Megacharger supercharging system, the battery pack delivers exceptional long-range performance, ultra-fast energy replenishment, and reliable durability. It complies with global automotive safety and environmental standards, redefining the driving experience for mid-size electric SUVs.

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.
