Solid-State Battery Has 2x the Energy–and No Anode
Lithium ion batteries set the standard because they have an acceptable level of all the key metrics: energy storage by weight; energy storage by volume; discharge rate; charging rate; production costs.<p>Every single one of these big breakthrough announcements touts how great this new tech is- in just one or two particular metrics.<p>The problem is that Li-Ion batteries are just barely acceptable in all of those metrics. No new battery is going to replace them unless they can match Li-Ion in every metric and beat them in at least one.
