"The plan of getting rid of cobalt completely was hinted at quite some time ago also by Elon Musk.Panasonic for a long time was the primary/near-exclusive battery supplier to Tesla, but in the most recent years, the company teamed also with Panasonic may be willing to step up its game to stay competitive for Tesla, the world's biggest electric car manufacturer.
""A cobalt-free version on the other hand would cut reliance on a costly and controversial component, which makes batteries stable but poses ethical issues given controversial labour conditions in top producer the Democratic Republic of Congo. Their 1,200lb Model S 85kw battery is made up of 7,104 individual lithium-ion cells manufactured by Panasonic that are called 18650’s (in reference to their 18mm in width and 65mm in length).
InsideEVs: Brasil Last April, Elon Musk promised that Tesla would soon be able to power its electric cars for more than 1 million miles over the course of their lifespan. "The only two Tesla models that currently use the "2170" batteries are The date of September 2020 is when Elon Musk will hold "Panasonic has already cut cobalt content to under 5% in the NCA cathode and plans to improve its batteries in stages, its U.S. EV battery chief Yasuaki Takamoto told Reuters. Tesla’s Batteries have gone through 3 stages: Stage 1 was from 2009-2012 found in the Roadster and Model S. Stage 2 was from 2016-2018 and powered the Model S Gen II, and the Model X. Tesla Here’s what’s in each cell: Cathode: The Tesla Model S battery cathode uses an NCA formulation with the approximate ratio: … The report does not specify whether we are talking about gravimetric or volumetric density (or both).Panasonic produces cylindrical "2170" type cells - nickel-cobalt-aluminium (NCA) chemistry - for Tesla at the While the 20% improvement over five years is significant, probably it will be divided into smaller steps and it seems that the first The Japanese company is ready with improved technology and "Panasonic has already developed technologies resulting in a more than 5% increase in the energy density of “2170” cells.From September, the firm will start converting lines at its factory in Nevada that it operates with Tesla as it prepares to further boost the energy density of the cells, Takamoto said.

""To control safety risks associated with higher density and less cobalt, Panasonic is adjusting the composition and design for better thermal stability, Takamoto said. If Tesla were to use the patent-pending technologies to make its own battery cells ready for series production, the company would probably rely on NMC cells for its potential own battery cell production … If you're like us, you probably have a few questions about the batteries in assorted Tesla vehicles but haven't had the opportunity to ask.
