It is reported that the Berlin Gigafactory is under internal construction and plans to start production of 4680 batteries in the first quarter of 2023. In terms of output, the Berlin Gigafactory can produce up to 500,000 electric vehicles per year, and Tesla plans to produce 4,680 batteries to meet the needs of 500,000 electric vehicles per year.
The Tesla 4680 battery uses a larger cell and new dry electrode coating technology, Musk said, the 4680 battery can save about 86% of the cost, and the cost per kWh can be reduced by 69%. In August, Musk told shareholders that Tesla expects to have mass production of the 4680 battery by the end of the year. But Stan Whittingham, co-inventor of the lithium-ion battery and 2019 Nobel laureate, believes Musk is too optimistic about the timeframe for commercialization of the new technology.
On September 23, 2020, Tesla officially released the 4680 battery at the Battery Day event, and plans to officially put it into production this year. Tesla said that the single energy of the 4680 battery has been increased by 5 times, the cruising range of the vehicle can be increased by 16%, the power has been increased by 6 times compared with the battery with tabs, and the power output has been increased by 6 times.
