The reason we don’t see exploding battery attacks more often is not because it’s technically hard, it’s because the erosion of public trust in everyday things isn’t worth it.

edit: after 20 comments, i'm adding a post description here, since most of the commenters so far appear not to be reading the article:
This is about how surprisingly cheap it is (eg $15,000) to buy a complete production line to be able to manufacture batteries with a layer of nearly-undetectable explosives inside of them, which can be triggered by off-the-shelf devices with only their firmware modified.
The title is a copy+paste of the first sentence of the third paragraph, and it is not misleading unless you infer "exploding batteries" to mean "exploding unmodified batteries". But, the way the English language works, when you put explosives inside an XYZ, or do something else which causes an XYZ to explode, it becomes an "exploding XYZ". For example:
That fact also is not what the article is about.
It doesn't matter that it's written in the article you took it out of context and then made it the title thus changing the meaning of the sentence.
I have had this conversation with so many people who seem to be under the mistaken delusion that any and all batteries can be made explosive, and you editorializing the title like that is massively unhelpful.
