Tesla, new advances on 4680 cells: increased production for tests


Within the financial results for the third quarter of 2021, Tesla provided a brief update on the works development of 4680 cells . As we know, the new batteries will be key to Elon Musk's company's growth plan. The last update dates back to the end of July when the American manufacturer had made it known that it had made progress but that there was still some work to be done to get the new cells to mass production.

The US company has made further progress and increased production of battery packs used for testing purposes, according to the release. So far, Tesla points out, the test results have met their expectations.

The internal design of the 4680 cells continues to progress. We are producing an increasing number of battery packs for test purposes and, so far, the test results meet our expectations. The front and rear frame pieces, both of which are required for our battery pack structural architecture, are manufactured at Gigafactory in Texas.

This is certainly important news that suggests that the work is well underway. When will we see them on vehicles? In April 2021, Elon Musk was talking about at least 12 months of further waiting before everything was ready. Drew Baglino, Tesla's SVP Powertrain and Energy Engineering, pointed out during the discussion on the quarterly that the new cells should be ready early next year. Therefore, more & ugrave; or not in line with Musk's past predictions.

However, Baglino also added:

This is; a new architecture and unknown unknowns may still exist.

We don't know exactly what the pilot production numbers are. The sure thing is; that Tesla will have to thoroughly test its new cells before starting mass production to be sure of their reliability.


Tesla also provided more details about the batteries used by its electric. The American car manufacturer has once again confirmed the will & agrave; to use LFP cells (lithium-iron-phosphate) on its Standard Range models produced around the world.

These batteries have some important advantages such as lower costs and better reliability in time. Furthermore, they do not require nickel or even cobalt. However, on the other hand, they have a density; lower energy and & quot; suffer & quot; more low temperatures.
