For those (like me) who are unaware of the value of an ultra capacitor in an EV environment, the following is one source of explanation:

Maxwell Ultracapacitors: Enabling Energy's Future

Basically, these are a complement to a battery storage system. They are used when quick bursts of power are required that would sacrifice battery capacity and longevity. These have many current uses, and explain Tesla’s interest.

My experience with ultra capacitors has to do with magna forming capability, which may lend itself to lower cost battery manufacturing. Current day aluminum baseball bats are magnaformed.

I've previously read some on this topic. Interesting stuff, however, wondering its relevance to Rivian since you posted this in the Rivian General Discussion category and made no reference to Rivian. Perhaps better placed in the Off Topic category unless you had some implied reference to Rivian to use this tech?
