While the limit is important for appliance electronics like laptops it doesn&amp;#x27;t have any impact at all on electric vehicles which are all mostly LiOn powered. 50% more range or 50% less weight would be an interesting change to put in the mix at Tesla for example.&lt;p&gt;If you look at where batteries are going to be in volume in the next 20 years it will be in grid storage, off-grid house energy storage, vehicles, and potentially small industrial tools.&lt;p&gt;Of course if this particular breakthrough actually makes it into batteries we will all be pleasantly surprised, as battery &amp;quot;breakthroughs&amp;quot; have a success rate quite a bit lower than &amp;#x27;venture funded startups&amp;#x27; :-)</text></comment>

I can use the power outlet on the plane if I&amp;#x27;m on a flight longer than that.&lt;p&gt;However, I would love 50% more battery lifetime in my phone without adding more weight or volume.&lt;p&gt;Or 50% more range in an electric car (or reducing the size&amp;#x2F;weight&amp;#x2F;cost of the battery pack).&lt;p&gt;There are lots of applications for batteries that don&amp;#x27;t involve taking large batteries on the plane.</text></comment>
