I keep seeing a lot of information about “breakthroughs” in solid state batteries for electric cars. People seem really excited about it and companies seem to be working hard to perfect it.
But I’m struggling to understand why they’re superior and what makes a solid state battery such a “breakthrough” technology. Hoping someone can explain to someone who really doesn’t understand this stuff.

The majority of other battery types have some sort of liquid or gel inside them, which a solid state battery does not. How they work isn’t all that different or important, but the major takeaway is that they can hold more charge than other batteries. So you either get more KWh for the same weight.
Thats important for EVs because those battery packs weigh a ton (sometimes literally) so being able to pack in the same charge with less weight is ideal.
A solid state battery is a newer type of battery that uses solid electrodes and a solid electrolyte, instead of the liquid electrodes and electrolyte found in a lithium ion battery. This makes solid state batteries much more stable and safer than lithium ion batteries, as well as allowing them to be smaller and lighter.
