Startup Aquion prepares to ramp up production of products for storing power in remote microgrids.
To reduce costs, Aquion has decided to do all of its materials processing in-house. One of the first steps is running raw materials—activated carbon and manganese oxide—through a calciner, shown here, which treats them at high temperatures.
This finished manganese oxide cathode electrode is ready to be incorporated into a battery cell. Aquion’s sodium-ion batteries operate similarly to lithium-ion batteries, but they use far thicker electrodes that are cheaper to make and allow for simpler battery cells. The thicker electrodes are enabled by the use of a water-based electrolyte that’s more conductive than the organic solvent electrolyte that lithium-ion batteries use. (Aquion gets its name by combining aqua with ion.)
This machine uses small suction cups to pick up electrode wafers and place them into the battery case. It’s the same kind of equipment used in candy factories.
