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. (www.bunniestudios.com)

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.

screenshot of paragraph from the article saying "The process to build such batteries is well understood and documented. Here is an excerpt from one vendor’s site promising to sell the equipment to build batteries in limited quantities (tens-to-hundreds per batch) for as little as $15,000:" followed by a screenshot of "Flow-chart of Pouch Cell Lab-scale Fabrication" showing a 20 step process

Lithium burns intensely but it doesn't explode. An electric car can burn for a long time, but they don't explode. One of the comments says so

I understand that what happened in Libanon was that dedicated explosives were added to the devices, it was not the batteries exploding. But that does not take away the conclusion of your story.

It shouldn't be undetectable. Throw a device from s series into a fire as a spot check and if it burns it's ok, if it explodes give the entire series to your enemy's kids to play with.
