Is every promising technology gonna work out? Of course not. But there&amp;#x27;s valid reasons to be interested and excited. I &lt;i&gt;like&lt;/i&gt; that these stories appear on HN so I can keep a rough understanding of how research is progressing. And usually there&amp;#x27;s some comments here from people who know the field a lot better. But to find those gems I have to scroll past a whole crowd of people posting this self congratulatory snark.</text></comment>

As a matter of fact I think this should be posted every time there is a new battery announcement so we can all do the tick boxes.&lt;p&gt;[ ] it lacks thermal stability at low or high temperatures.
[ ] it is too likely to catch fire or explode.
[ ] it is impractical to manufacture at scale.&lt;p&gt;These are the only three I see as problematic or unknown. Which is not that bad.</text></comment>
