Tesla is describing a step by step path to halve the cost of batteries and increase production by 7 times for each battery line.
It will take 12-18 months to get volume production. It will take 3 years to fully realize the 69% reduction of factory investments and 56% reduction in battery costs and the 50+% increase in range.
They will make a compelling $25,000 electric vehicle and are targeting 20 million cars per year.
The Model S plaid will be available to order now and will be delivered by the end of 2021.
The large cell is confirmed. It is a 4680 cell. The size increase alone will increase storage by 5X and range by 16% and power by 6X.
Tabless battery technology is also confirmed.
They are on the fourth revision of the Maxwell dry battery cells.
They will scale the roadrunner pilot plant to 10 GWh per year within one year.
Elon mentioned that the next battery factories will have about 200 GWh per year of production. Each line will produce 20 GWh.
They will reduce the investment needed for factories by 4X and reduce the factory space by 10X.
Tesla plans to have 100 GWh/year of the new battery factory by 2022 and at least 3 TWh per year by 2030. They want to reach a steady-state of 10 TWh/year of production.
They have silicon anodes.
They have reduced the costs of their use of silicon, lithium and nickel. They will get closer to using raw materials. They will not need to process the materials as much or at all.
There is enough lithium in Neveda to electrify all 300 million cars in the USA and they will recycle the nickel, lithium and other materials.
They have made structural batteries. The pack is structural. The non-cell portion of the battery is now structure for the car and is a massive weight reduction. The mass of the car body will be 10% less and will give a 14% range increase.
