Tesla’s 4680 battery cell program has achieved significant progress during the second quarter of 2024, with notable advancements in production and technology.
In its Q2 2024 Update Letter, Tesla reported a 50% increase in the production of 4680 cells compared to the first quarter of the year. Additionally, the company successfully constructed its first validation Cybertruck equipped with in-house dry cathode 4680 cells, marking a crucial step towards cost reduction.
The update emphasized the importance of cost reduction across Tesla’s product range, noting that the validation of the Cybertruck with in-house dry cathode 4680 cells represents a major milestone.
Tesla highlighted its commitment to improving production efficiencies and reducing costs, which remains a top priority for the company.
Recent reports from the Chinese publication LatePost suggest that Tesla is preparing to mass-produce and install 4680 cells with dry electrodes in consumer vehicles by the end of the year.
The current iteration of Tesla’s 4680 cells features a dry electrode process for the negative electrode, while the positive electrode is sourced from a supplier and produced using conventional wet cathode methods. The complete iteration of the 4680 cells, once fully implemented, could result in significant cost savings for Tesla’s electric vehicles.
Lars Moravy, Tesla’s Vice President of Vehicle Engineering, summarized the achievements of the 4680 program during the Q2 2024 earnings call.
He noted that 4680 cell production had increased by 51% in Q2, significantly reducing the cost of goods sold (COGS). Tesla is currently producing over 1,400 Cybertruck units equipped with 4680 cells per week and aims to continue ramping up production while driving down costs further.
Moravy also highlighted the successful construction of the first validation Cybertruck using mass production equipment with the dry cathode process, a major technical achievement for the company.
Tesla is on track to launch production with the dry cathode in Q4 2024, aiming to achieve cell costs significantly below available alternatives, which aligns with the original goals of the 4680 program.
