At its Battery Day event, Tesla unveiled its new 4680 battery cell developed in-house and the manufacturing process behind it.

The highly anticipated presentation went deep into details about all the different pieces of material science, design, and manufacturing innovations that it took to deliver the masterpiece of a puzzle that the automaker needed to put together to reduce battery costs by more than 50% in just 3 years…

We are talking about buying companies like Maxwell and Hibar, and applying for patents on new technology, like a tabless battery cell and a cell to pack design.

While all these moves were mostly evaluated on their own merits, it wasn’t clear how all those things would fit together.

And then, by combining all these things together, Tesla achieves a battery cost breakthrough with a 56% reduction in cost per kWh:

What is most impressive is how all those innovations work together. Each result in an incremental improvement to battery technology, but if you combine them together, you get breakthrough-level performance and cost:
