Donut Battery does not come in one fixed format. From one baseline chemistry, we can tune voltage, energy density, cycle life, charge rate, temperature, and cost, and shape the cell into almost any form factor, from a thin pouch to a curved design that fits the body of the product. The cell is built around the application, not the application around the cell. A drone, a robot, and a grid storage system can each get a cell designed for the job it actually has to do. This episode is about that freedom, and the new business cases it opens that did not exist before.

Amazing this asshat is still talking. Marko's folly.

None of these production ready advancements is going to stop me from dreaming about the next tech: Quantum Batteries:

Very similar to Donut and Fusion power. Lots of buzz words and future pronouncements but very little substance. Today’s batteries C rate may not increase with size but the amount of kWh/hr they can store does (see Silverado or Sierra). Also the Chinese pretty much have the charge time solved. The next big problem in batteries is recycling. New cheaper batteries lack expensive minerals. LFP batteries cost more to recycle than their value during salvage due to shipping costs.
