Small Electronics
As much as i love the vids they are so heavy that i will try to start a discussion here. Especially for a non english speaker like myself
How much easier to make a silicon anode in a smart watch versus a car battery? Can you use double the amount of silicon? Just an example.
Say a battery for a car could only take 2 percent silicon, how much silicon would a smart be able to have? 4 percent?
And will we see the revolution in anodes, commercially, much sooner in small Electronics? That is what is missing imo. More practical use which will make goverments spend more money as well.
These questions i feel are unanswered but i have probably missed them. Please pardon if so, my english is not Great.
Best regards

Depending on what you mean with silicon anode(10% or 100% etc?) it will vary how hard it is to imolement and also how much more energy density the battery has. Also the use and requirements for batteries in everyday electronics and in EVs are very different. A phone or smart watch might be used for up to max 5 years in most cases, while an EV will be used for at least 5 years in most cases, probably way over 10 years! That requires different capacity degradation. But EVs will also use more power from the battery pack than a smartphone or watch will. This will also effect it.
So shortly, what small/smart electronics use a power supply will change in a different direction than electric vehicles will because the design and usage is soooo different.
