4680 battery is the key technology for Tesla to reduce costs

The 4680 battery is Tesla's core technology for reducing manufacturing costs. According to reports, in 2020, Musk said that this battery can reduce the cost of batteries by 50%, but this requires Tesla to overcome the dry-process positive and negative electrode processes. However, as of March this year, the annual production capacity of 4680 batteries is only enough to equip 60,000 Cybertrucks, and the cost is higher than expected. Tesla is still unable to mass-produce dry-process positive electrodes.
