Panasonic plans to start mass production of new lithium battery products for Tesla in early 2023, which will increase battery life by 20%, thereby maintaining a competitive advantage with rivals in South Korea and China. The so-called new type of battery, the 4680 electrodeless ear cylindrical battery, that is, the diameter of 46mm, the height of 80mm, it was released on tesla battery day in 2020.
Previously, Tesla had claimed that the energy density of the 4680 battery cell was increased by 5 times, the mileage of the whole vehicle was increased by 16%, the power was increased by 6 times compared with the polar ear battery, and the power output was increased by 6 times.
In addition, in terms of innovative manufacturing and assembly, Musk said that the 4680 battery has saved about 86% of the cost in total, while the cost per kWh has been reduced by 76%. Compared with traditional fuel vehicles, electric vehicles have more cost advantages.
However, judging from the time, the mass production time of the 4680 battery is more than 1 year later than the original schedule. Earlier comparative pictures show that the 4680 battery cell is huge compared with Panasonic's 1865 and 2170 batteries.
