How to make battery cells?

Step 1: Electrode Slurry: The powder containing the active material (such as lithium) in the electrode is mixed in a large bowl with a binding material (which acts like glue) to form what scientists call a slurry or gooey batter.

Step 2: Electrode Coating: The slurry is then applied to very long (up to hundreds of feet) pieces of foil, and the electrodes are baked into a solid by rolling slowly at high temperatures (up to 300 degrees Fahrenheit).

Step 3: Electrode Punching: Cut the baked electrode rolls into small pieces and place them under a super sharp rectangular mold. With the sudden action, the mold quickly pressed down the electrode sheet and cut out a single electrode battery sheet.

Step 4: Electrode Stacking: An automated machine uses suction to pick up and release the cut sheets of electrode material, wrapping an insulating layer between each sheet. The result is a stack of credit-card-sized electrodes that spit out of the machine as the metal arm turns.

Step 5: Bag Making: Press the special moisture-proof material into a rectangle. Electrode stacks are inserted into the resulting form to create pouch cells.

Step 6: Electrolyte Injection: Inject the electrolyte into the opened battery bag.

Step 7: Battery Sealing: Heat seal the battery bag soaked in electrolyte and place in a vacuum chamber to remove excess air from the bag.

These pouch cells will then be continuously charged and discharged for at least two weeks in an environmentally controlled room that simulates extreme weather (between 20 and -140 degrees Fahrenheit).

If the test pouch battery performs well, its unique combination of different materials could allow us all to live longer and better. When a promising battery chemistry is identified, the national laboratory works with private companies to license the technology, and these companies develop it into a product we can all buy and use.
