The Tesla 4680 battery refers to the battery with a diameter of 46 mm and a height of 80 mm, named after its size. The shape is cylindrical, which is different from the mainstream square battery. Tesla's 4680 battery currently uses a ternary lithium battery technology route, and it is not ruled out that lithium iron phosphate batteries will be launched in the future.
The Tesla 4680 battery is a new type of large lithium-ion battery launched by Tesla. Its main features, advantages and disadvantages are as follows:
Advantages of Tesla 4680 battery:
High energy density: The Tesla 4680 battery adopts a larger battery size and a new design to provide higher energy density and make the battery capacity larger, thereby extending the cruising range of electric vehicles.
Improved heat dissipation performance: 4680 battery adopts an irregular surface design, which improves the heat dissipation effect, makes the temperature rise of the battery more gentle during high-power discharge, and improves the service life and safety of the battery.
Higher charging rate: The 4680 battery has a higher charging rate, which can be charged faster and shortens the charging time.
Cost reduction: The 4680 battery uses a new production process, including the use of fewer parts and a more efficient production line, which is expected to reduce production costs and drive down the price of electric vehicles.
Disadvantages of Tesla 4680 battery:
Technical novelty: As it is a brand new battery design, the technology of the 4680 battery is relatively new, and there may be technical immaturity and reliability risks.
Production scale and supply chain: Large-scale production of 4680 batteries may require adjustments to Tesla's production equipment and supply chain, and there may be challenges such as short-term supply shortages.
Cost and investment: Although the 4680 battery is expected to reduce production costs, new production processes and equipment may require substantial investment, which may put some economic pressure on Tesla.
Overall, Tesla's 4680 battery has brought many improvements in terms of energy density, charging speed and heat dissipation performance, and is expected to have a positive impact on the electric vehicle industry, but because it is a new technology, it still faces some technical and production challenges .
