What we're trying to do is have all of the mass and volume be used for the purpose it is to be used for, which is to power the device.

Now it's simply a matter of designing the other components, and we'll be able to form batteries by simply pouring all the ingredients together and letting them self-assemble. Plus we can make them at room temperature in very safe conditions, instead of the high temperatures and dangers usually associated with battery production.

This could only be done through self-assembly.
