Is Tesla Moving Their Battery Strategy to Prismatic Cells? In a fascinating shift, reports have emerged suggesting that Tesla may be transitioning from its traditional cylindrical battery cells to prismatic cells for the standard range Model 3s produced in China. This strategy has yet to be confirmed by Tesla but signals a significant change in their battery approach, with implications for production costs and vehicle performance.

Overview of Tesla's Current Battery Technology​

Tesla has consistently used cylindrical cells in its vehicles, such as the popular Model S, Model X, and Model 3. These battery packs are composed of thousands of smaller cells (like the 2170 size) that provide a compact, efficient energy source. However, the company is exploring new avenues, particularly through a partnership with the Chinese battery manufacturer CATL, known for producing lithium iron phosphate (LFP) battery cells.

Prismatic Batteries: An Introduction​

Prismatic batteries differ significantly in design, resembling rectangular bricks rather than cylindrical shapes. This allows for a more efficient utilization of space within the battery pack and can potentially reduce manufacturing costs—up to 25% cheaper according to some estimates. For Tesla's standard range Model 3s, this could translate to significant price savings, making the vehicles more competitive in the price-sensitive Chinese market.

The Chemistry Behind the Transition​

Tesla's switch to prismatic cells involves using LFP chemistry, which is recognized for its abundance and lower cost compared to cobalt-based batteries. This will not only help Tesla reduce its reliance on expensive and less sustainable materials, but it may also extend the lifespan of these batteries due to the stability of LFP.

Challenges and Considerations​

While prismatic cells offer potential benefits, they come with their own set of challenges. One major concern is the need for tailored designs to fit specific vehicle architectures, which could complicate production processes. Additionally, prismatic batteries may require different cooling specifications to manage heat effectively, something Tesla has done well with its cylindrical cells using intricate cooling systems. Given these changes, Tesla will need to manage its supply chain carefully. Different battery types may introduce complexities in production that could lead to fluctuations in quality and performance across their vehicle lineup.

Conclusion​

Tesla's potential shift to prismatic cells signifies a bold step that could reshape its battery strategy and manufacturing efficiencies. While there are significant benefits to this approach, such as cost reduction and improved sustainability, the practical implementation will require careful navigation of design, production, and supply chain dynamics.
