4680 Battery Pack for Tesla Model 3 4th Gen (2023–2026)

Product Overview

This 4680 cylindrical high-nickel NCM ternary lithium battery is exclusively engineered for the 4th Generation Tesla Model 3 (2023–2026), available in 78.4 kWh, 82 kWh, and higher capacity variants. It integrates Tesla’s core innovations including tabless structure, dry electrode technology, and high-nickel NCM cathode materials (Ni>88%), delivering a revolutionary leap in energy density, charging speed, and durability compared to previous battery generations. Fully compatible with the 4th Gen Model 3’s Cell-to-Chassis (CtC) design, powertrain, and Megacharger supercharging architecture, the battery pack ensures exceptional long-range performance, efficient energy replenishment, and reliable operation, while complying with global automotive safety and environmental standards, redefining the driving experience for electric vehicles.

Key Features

• Advanced 4680 Cylindrical Design: 46mm diameter and 80mm height, combined with tabless structure that shortens current path by 95%, reduces internal resistance by 70-80%, and improves heat dissipation efficiency by 600% compared to 2170 batteries.
• High-Nickel NCM Cathode: Adopts high-nickel NCM ternary materials (e.g., NCM811 with 81.6% nickel content), eliminating cobalt to reduce cost while boosting energy density and cycle life.
• Dual Capacity Options & Expandability: 78.4 kWh and 82 kWh standard versions, with support for higher capacity variants (82 kWh+), tailored to different range requirements of the 4th Gen Model 3.
• Dry Electrode Technology: Solvent-free manufacturing process simplifies production, reduces energy consumption by 50%, and increases energy density by 5% through thicker electrode coatings, while lowering overall production costs.
