Why is the 4680 Better than the 2170?

The Tesla 4680 battery offers several advantages over the 2170 battery, including higher energy density, faster charging capabilities, and cost efficiency. The 4680 battery is designed to enhance performance and reduce production costs, making it a significant innovation in electric vehicle technology.

Key Differences Between 4680 and 2170 Batteries

  1. Size and Design
    • The 4680 battery has a diameter of 46 mm and a height of 80 mm, while the 2170 battery measures 21 mm in diameter and 70 mm in height. The larger size of the 4680 allows for greater energy capacity.
    • The 4680 features a tabless design, which reduces the electrical path and minimizes resistance, leading to improved efficiency and reduced heat generation during operation.
  2. Energy Capacity
    • The capacity of the 4680 battery is significantly higher, with estimates around 26,000 mAh, compared to the 2170’s typical capacity of about 4,800 mAh. This increase in capacity translates to longer driving ranges for electric vehicles.
  3. Charging Speed
    • Due to its innovative design, the 4680 battery can achieve faster charging rates. It is reported that it can charge up to 60% in just 20 minutes, which is a substantial improvement over the 2170 battery.
  4. Cost Efficiency
    • The production costs for the 4680 battery are expected to be lower due to its simplified manufacturing process. Tesla aims to reduce costs by integrating the battery into the vehicle’s structure (Cell-to-Chassis or CTC technology), which eliminates unnecessary components and reduces weight.
  5. Performance Under Load
    • The 4680 battery’s design allows for better performance under high load conditions. Its lower internal resistance means that it can deliver power more efficiently, making it suitable for high-performance applications such as electric vehicles.
