The main characteristics and advantages and disadvantages of Tesla 4680 battery

The Tesla 4680 battery refers to a battery with a diameter of 46 millimeters and a height of 80 millimeters, named after its size. The shape is cylindrical, different from mainstream square batteries. Tesla 4680 battery currently adopts the Technology roadmap of ternary lithium battery. It is not ruled out that Lithium iron phosphate battery will be launched later.

The Tesla 4680 battery is the latest large-scale lithium-ion battery launched by Tesla, with the following main characteristics and advantages and disadvantages:

Advantages of Tesla 4680 batteries:

High energy density: The Tesla 4680 battery adopts a larger battery size and new design, providing higher energy density, resulting in larger battery capacity and extending the range of electric vehicles.

Improved heat dissipation performance: The 4680 battery adopts a surface irregular design, which improves the heat dissipation effect and makes the temperature rise of the battery smoother during high-power discharge, improving the battery’s service life and safety.

Higher charging rate: The 4680 battery has a higher charging rate, allowing for faster charging and shortening charging time.

Cost reduction: The 4680 battery adopts a new production process, including the use of fewer parts and more efficient production lines, which is expected to reduce production costs and drive down the price of electric vehicles.

Disadvantages of Tesla 4680 batteries:

Technical novelty: Due to its brand new battery design, the 4680 battery has relatively new technology, which may pose technical immaturity and reliability risks.

Production scale and supply chain: Mass production of 4680 batteries may require adjustments to Tesla’s production equipment and supply chain, which may pose challenges such as short-term supply shortages.

Cost and Investment: Although the 4680 battery is expected to reduce production costs, the new production process and equipment may require significant investment, which may bring certain economic pressure to Tesla.

Overall, Tesla’s 4680 battery has brought many improvements in energy density, charging speed, and heat dissipation performance, which are expected to have a positive impact on the electric vehicle industry. However, as a new technology, it still faces some technical and production challenges.
