Tesla Battery Day 2020: The New Cobalt Free Tabless Batteries Called 4860 Cells

Geschreven op 20-11-2020 - Erik van Erne. Geplaatst in Vervoer en OV Facebooktwitterredditpinterestlinkedintumblrmail

Elon Musk made some big announcements at Tesla Battery Day 2020. The company is planning to get rid of Cobalt in their batteries and to manufacture its own “tabless” batteries, called 4860 cells.

This type of battery is six times more powerful, and the range will be increased by 16 percent. The new battery technology will make a $25,000 Tesla car a reality. Tesla Model S with Plaid powertrain also was announced, which can reach 60 mph in less than 2 seconds and break records on tracks. Max speed: 200 mph.

    Panasonic to launch 4680 battery cell production in 2021

    Panasonic wants to start the production of prototypes of the new 4680 battery cell presented by Tesla at “Battery Day” as early as 2021. Most likely, production will take place in the Nevada Gigafactory.

    Tesla had initially announced the new battery cell format at their Battery Day earlier this year. The benefits of the new cells designated 4860 are that they are bigger and claimed to be better, not the least because of advances in production. The key here is the use of a dry electrode, to rely primarily on nickel, and a ‘tabless’ design. The cells will also integrate into the vehicle as an entirely structural component. The overall goal is a range increase of up to 54% and simultaneous reductions in kWh price by 56% and the investment per GWh by 69%. The 56% cost reduction would bring Tesla within reach of $50/kWh battery price.

    While Tesla is also launching their own in-house production, they will have to rely on suppliers as well to deal with the planned battery and vehicle mass production. Elon Musk also confirmed this on Twitter just before the Battery Day itself: “We intend to increase, not reduce battery cell purchases from Panasonic, LG & CATL. However, even with our cell suppliers going at maximum speed, we still foresee significant shortages in 2022 & beyond unless we also take action ourselves.”

    A Look At Tesla’s 4680 Cell Production

    Tesla recently provided a sneak preview of its 4680 cell production planned for Gigafactory Berlin in the company’s latest recruitment video on LinkedIn. It reveals several small details of the 4680 production process that might be of interest to competing automakers in addition to potential employees.
