Tesla's Battery Ambition: From the Grand Vision of "Battery Day" to the Challenges of Reality

In September 2020, Tesla unveiled an ambitious blueprint to the world at its "Battery Day" event: a $25,000 electric vehicle powered by a revolutionary 4680 battery that would completely transform the electric car industry. However, three years later, the reality is far from the initial vision. Tesla's battery ambitions are facing significant challenges, from technical hurdles and cost pressures to internal turmoil, making Tesla's battery journey a winding one.

The Grand Promises of "Battery Day"

At "Battery Day," Tesla CEO Elon Musk ambitiously announced that the $25,000 electric vehicle would be equipped with a new type of battery called the 4680, twice the size of previous batteries, with five times the energy density, six times the power, and a 16% increase in range. To achieve this, Tesla planned to adopt a revolutionary "dry" electrode manufacturing process, replacing the traditional "wet" process to reduce production costs and improve battery performance.

Challenges of Dry Electrode Technology

Tesla's enthusiasm for dry electrode technology stemmed from its potential to reduce costs and increase efficiency. However, reality has proven that implementing dry electrode technology is far from simple. Tesla has encountered numerous technical hurdles during production, including dry powder damaging production equipment, difficulties in cathode manufacturing, and battery core collapse.

Delayed and Shifting Targets

Tesla initially planned to launch the $25,000 electric vehicle in 2023, but this plan was shelved due to the slow progress of battery technology development. Musk shifted his attention to the development of self-driving taxis and adjusted the development goal for the 4680 battery to reduce costs and expand production. However, the 4680 battery has also encountered issues in real-world applications. Its energy density and range have not met expectations, and it offers no clear advantage compared to traditional batteries supplied by vendors.

Internal Turmoil and Executive Departures

Tesla has experienced internal turmoil during the 4680 battery development process, with multiple executives leaving, including Drew Baglino, the vice president responsible for battery research. This has raised questions about the importance of Tesla's battery innovation for future development.

Pressure and Deadlines

Despite the numerous challenges, Tesla has not given up on the development of the 4680 battery. Musk has set a deadline for the team by the end of the year to solve technical problems, reduce costs, and accelerate the development of dry coating. Tesla aims to validate the feasibility of its large-scale production methods by September and address the battery core collapse issue as soon as possible.

Lowered Expectations and Strategic Adjustments

Over time, Musk's expectations for the 4680 battery seem to have lowered. He no longer views battery technology as Tesla's core competitive advantage, instead positioning it as a way to reduce costs. Tesla may focus more energy on other aspects of the vehicle to improve its cost-effectiveness.

Conclusion: Tesla's Battery Path is Full of Challenges

Tesla's battery journey is full of challenges. While the ambitious blueprint of "Battery Day" has not been fully realized, Tesla continues to explore and innovate. Ultimately, whether Tesla can overcome these challenges and achieve its battery ambitions will depend on its technological breakthroughs and the intensity of market competition.
