Sure, just like large fuel tanks are a fire hazard. We have to take the correct precautions. In the case of batteries that is make things with the right margin of safety, and be careful how we charge. (probably more, I'm not a battery expert)

Battery chemistry is another one. There are chemistries[1] that are much less, if at all, prone to go up in flames on their own.

Of course there's usually always a tradeoff with other properties, like weight or cost.

Batteries are a much greater hazard than gas fires. Not even close. To start, you can actually put gas fires out with a reasonable amount of water before its fuel source is burnt up.
