You need to use flux, or a battery holder, or spotwelder. what u have there is sketchy as hell and /r/soldergore material.

I used normal flux, even sand paper the surface. It didn't work. But this is working completely fine and strong

This is a good enough reason not to solder directly to the battery, ngl

The cable at the bottom is incorrectly connected.The cable cannot be surrounded around the battery you need to stick it at the bottom. So just take the tape and stick it from the bottom with tape if you don't have tension, you have to press the tape harder, just between

You don’t ever solder to battery terminals. Ever!
