Tesla already has cobalt down to 3% in their batteries, so it isn't a huge expense for them.
Is that real? If so, it's worth the crash to be proven invincible.

That doesn't sound right at all. Supercapacitors work by storing static electricity on an enormous surface area. Their capacity doesn't increase after many cycles, at least not by 6x. Furthermore, they store a fraction of the energy that chemicals can.
I need to have the principle function of the battery explained in layman's terms. There are only 2 ways that it could possibly store energy; as potential chemical reactants, or as a static charge.
