Tesla’s new 4680 battery cell is an “A-plus” design according to Shirley Meng, a scientist from the University of California San Diego.
But she added that Tesla can’t achieve is ambitious goals by itself — to get to ten terawatts of worldwide capacity, other players will be required.
“The world needs so many batteries,” she said.

Tesla’s Battery Day this week brought big news to the metallurgy and chemical-engineering worlds: the company had developed a new cylindrical battery cell, dubbed the “4680,” that’s much larger than the 2170 cells it’s currently using.
While the 4680 cells remain at the prototyping stage and shouldn’t enter mass production until 2022, CEO Elon Musk and his engineers are confident enough in the new form factor to start rethinking the design of Tesla’s
During Tesla’s long-awaited Battery Day, CEO Elon Musk showcased a number of new technologies the automaker is working on, but as expected all seem to be somewhat far on the horizon.
One of the most talked about pieces of battery tech in the weeks leading up to the event was Tesla’s intent to manufacture tabless battery cells using use a newly-patented method, thereby using fewer parts inside each battery pack. The automaker refers to this new type of cell as the 4680 cell, for the 46 millimeter by 80 millimeter cell dimensions, and plans to produce them in-house as expected.
The company uses 2170 cells today, manufactured by Panasonic in the automaker’s Gigafactory plant, which are used in the Model Y and the Model 3. The Tesla CEO suggested that experimental production is somewhat close to operating at the pilot plant level, but did not
