In September 2020, Tesla released the "4680" new battery on its battery day, which is a cylindrical battery with a diameter of 46mm and a height of 80mm, compared with the 2170 battery currently used, Tesla officially said that the capacity of the 4680 battery will be increased by 5 times, the mileage will be increased by 16%, and the cost will be reduced by 14%.
In addition, Tesla announced that the 4680 battery will debut in the mass production car in 2022, but did not say which model the battery will be equipped with, but according to the information disclosed by foreign media, Tesla's 4680 battery will first be installed in the Tesla Model Y model.

At the end of 2021, some foreign netizens in Tesla's Texas factory photographed a Model Y white body that is very likely to carry a 4680 battery, and recently there were foreign media reports that the first batch of Model Y produced by Tesla's Texas Super Factory in the United States may have officially rolled off the production line, and the new car will be equipped with Tesla's previously released new structural battery technology, that is, 4680 battery technology.
This does not mean that the mass production of 4680 batteries may come quickly, then Tesla's new price reduction tide will soon come, and consumers can also buy cheaper Teslas faster!
But it is worth noting that Tesla has also been exposed to the 4680 battery production capacity is blocked, and Musk has also admitted that large-scale production faces challenges. Because they're trying to inject a lot of innovative elements into this new battery, it makes the production line much more complicated than imagined.
So even if the 4680 battery is mass-produced, the 4680 battery will still not be used for all models, the Model Y model will be the first to be installed, and other models may be Cyberruck, semi and so on
In addition, Tesla's other best-selling model Model 3 is considered by some engineers to be unsuitable for assembling a 4680 battery due to body size problems, which will be mainly used in long-lasting vehicles, and the standard version of the model will continue to use non-4680 lithium iron phosphate batteries.
The most critical is that due to limited production capacity, this batch of models will not be synchronized to the Chinese-made Model Y in a short period of time, according to the plan, Tesla will plan to mass-produce 10GWh at the end of 2021, and it will still take some time to fully put into production, according to the expected time in China will wait until around 2023.
