A few days ago, Tesla CEO Elon Musk tweeted a message promising to show “a lot of interesting»At the upcoming Battery Day event next week. Obviously, the main event will be the demonstration of new traction batteries of our own design. In anticipation of this event, the first images of the storage cells of the company’s new batteries appeared on the Web.
Earlier this year, it became known that Tesla is busy with the Roadrunner project, in which the company has developed a new battery production system to significantly reduce the cost of producing electric vehicles. Little is known about Tesla’s new batteries, however. Now, on the Internet, there are probably the first images of Tesla battery cells. They were published by the resource Electrec, citing an anonymous source of the images, and later the authenticity of the photos was confirmed by another source of the portal.
Tesla still does not disclose the characteristics of the new cells, but the published images do reveal some details. The diameter of the new cell is about twice that of the Tesla 2170, which is currently used in Model 3 and Model Y electric vehicles and is manufactured by Panasonic at the Gigafactory in Nevada. The doubled diameter of the cell makes its volume four times larger. If the resulting volume is used efficiently, more capacity can be obtained while reducing costs due to fewer casings and fewer cells per package.
Tesla applied for a patent earlier this year for a new flat-electrode battery cell. The new cell design will reduce the internal resistance to the passing current, thereby increasing productivity.
Tesla is currently building a pilot production line to build new cells in Fremont, according to reports. In addition, in the future, Tesla plans to host a battery manufacturing system at its factory, which will be built in Texas.
