Tesla is working hard on a dry battery electrode manufacturing process, but the progress is slow to materialize. Nevertheless, a series of p
One of Tesla’s promises at Battery Day in 2020 was a novel battery manufacturing process that would drastically improve battery performance and cost structure. Tesla said the 4680 batteries would feature a silicon anode instead of graphite and a new dry cathode manufacturing process that could cut production costs in half while at the same time extending the battery life cycle.
The dry cathode manufacturing process is considered the holy grail of Li-Ion batteries and is the main reason Tesla bought Maxwell in 2019.
