According to German media BZ, Tesla demonstrated its 4680 battery technology in Grunheide, Germany last Sunday. Tesla said that Tesla is planning to launch an electric car equipped with 4680 batteries, they are faster, cheaper, and more environmentally friendly to manufacture.
Moreover, the Berlin Gigafactory is under internal construction and plans to start producing 4680 cells 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.
Furthermore, Tesla 4680 battery uses larger cells and new dry electrode coating technology. Musk said that 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 achieve mass production of the 4680 battery by the end of this 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.
