24M announce breakthrough in battery cost and charge time
Today 24M, founded by MIT professor Yet-Ming Chiang, announced a breakthrough in Li-Ion technology that allows for fast charging cheap batteries.
Fabrication of those cells should be fast and cheap too; eliminating several steps in the production process, making the production plant 10 times as cheap and 5 times as fast.

24M’s simple but breakthrough cell design is made possible by the semisolid thick electrode – a material science innovation originating in Dr. Chiang’s lab at MIT. Conventional lithium-ion battery cells have a large fraction of inactive, non-charge carrying materials – supporting metals and plastics – that are layered, one-on-top of the other, within a cell’s casing. Those inactive materials are expensive and wasteful. With the invention of the semisolid thick electrode, 24M eliminates more than 80% of these inactive materials and increases the active layer thickness over traditional Li-ion by up to 5x. Using thick electrodes, the cell also stores more energy, bettering the performance of the battery as well as its cost.

If this is true.... Wow!
