It’s pretty common knowledge that upgrading battery tech is going to be crucial to mass adoption of electric transportation of any type. Lithium Ion is an establish tech, but it’s too volatile and inefficient to encourage a breakthrough in electric vehicles. The betting currently seems to be on solid state batteries, which is why this solid state battery post outlining the pros and cons is interesting.
The long and short of it seems to be that solid state tech will charge much faster, be less likely to explode and provide more energy density, which is important to get away from range anxiety and other downsides to current Lithium tech. The problem is solid state is still tricky and expensive to mass produce, which means we’re still three to five years away from mass adoption. Shame. We’re optimists though, so hopefully there’ll be a breakthrough.
“VW says the battery will offer about 30% more range than a liquid one and charge to 80% capacity in 12 minutes, which is less than half the time of the fastest charging li-ion cells now available.”
