Ideal Battery in Circuit
What you are trying to do is a circuit which is not defined.

If you try to apply Kirchhoffs law to this circuit what will you get? The sum of the voltages is 1 V, there is no component where the 1 V will drop. So this circuit is not suited to be analyzed by this.

If you try to calculate the current with Ohms law, you end up dividing by zero. Which is not defined.

In the real world, you always encounter some non-ideal components. So even if you connect a superconductor directly to battery there will be a defined behavior because the battery has an internal resistance for example.
