Overlooking the cell chemistry issue...

... you cannot just dump unlimited current through a superconductor. Once you exceed the critical current density, your superconductor becomes a regular conductor.

Also the thing will be a really strong magnet while it is storing energy. Even if it doesn't rip itself apart it will stick to stuff amd lose energy.
And in any case whatever power source you're using cannot deliver infinite power.
Who said infinite power?
It's implied by instant charging. The power would be the battery capacity divided by 0.
No one means literally zero time to charge. A couple seconds compared to minutes or hours is virtually instant for practical purposes.
Let me keep being pedantic and notice that a typical phone capacity of 10000 Joules divided by 2 seconds is still 5 kW of power, so not a trivial amount. I'd think 30 seconds (333 Watts) is more realistic.
If we can even get the charge times for EVs down to the minutes to take to refill ICE tanks. It will basically remove the range anxiety problem.
That’s pedantic. No one means literal instant charging, just figuratively.
