Tesla will switch to “biscuit” batteriesSeptember 17, 2020
Next week Tesla may present fundamentally new batteries for its electric vehicles. They will be significantly larger than the existing ones and will ultimately increase the overall capacity and, at the same time, reduce production costs.
According to the British entrepreneur Simon Moores, who deals with lithium-ion batteries, the American automaker will start using a new battery format – Biscuit Tin, that is, a “biscuit cookie jar.” This unofficial name appeared due to the similarity of shape and size, Tesla itself will probably call them differently.
Recall that a few years ago Tesla switched from the 18650 format (diameter 18 and height 65 mm) to the larger 2170 (diameter 21 and height 70 mm, the last zero is reduced for convenience). This made it possible to slightly increase the specific gravity of the battery, since in the total mass of the battery less space is spent on the shell. They are now installed in Model 3 and Model Y.
Now the American company wants to take another leap forward and introduce significantly larger batteries. It is assumed that they will be produced at a new plant in Texas. The Cybertruck, Semi, Model 3 and Model Y will also be produced there. All these electric vehicles will probably receive new batteries.
What will become of the Model 3 and Model Y, now manufactured in Fremont? It is possible that their assembly will be stopped there.
The Tesla Battery Day event, where new generation batteries will be presented, will take place on September 22. All the details about the advanced batteries will be announced there.
