I hear a lot about e-bike and e-scooter batteries being a risk if bought cheaply whereas name-brands are better. I remember A Samsung Note phone having this problem as well. What causes this and how is it fixed/brought under reasonable control

The short answer is that batteries are an energy source, usually chemical energy if we’re talking about lithium ion batteries. They store energy until it’s needed, and then slowly release that energy in the form of electricity. If you were to compromise the physical battery, then you run the risk of all that energy releasing at once.
So why do cheaper batteries explode more often? The simple answer is that it’s cheaper because it uses cheaper material and build processes. The cheaper material may be easier to compromise, and the cheaper build processes may exclude additional safety measures.
That’s not to say every cheap battery will explode, not are expensive batteries perfectly safe. But batteries that are less well made will be more prone to accidental damage
