Another solid state technology. A few years ago the prediction was that someone would invent/discover a solid state battery that worked, and it seems like that is happening. And of course cheaper is better.

It's real easy for people to claim that their thing is *going to be* the holy grail of battery technology. Let's see if they can actually develop it into something commercially viable. I hope they can.

 

[Mister Dave]

We don’t have as many cycles as we need yet, but, you know, we’re working on it.

The anticipation is palpable.

The advanced alkaline is easy to make cheaply from abundant materials. I wonder about this mystery polymer though.

Another month, another lab breakthrough. The leap from lab to commercial production is littered with dashed dreams. One of these days, it will happen.

Meanwhile, battery tech improvement rates are about 7% per year. Result, the 2017 Bolt EV has almost 7 times the range as the first year Volt. The Bolt is also priced the same as the 2011 Volt.

It does have 7X the range but it also has a 4X larger battery. LOL We really do need a breakthrough. There are so many advancements in the solid state area that I'm pretty hopeful at least one of them will work.

I can't keep track of all the breakthroughs, so I don't know whether the new breakthrough is better than other breakthroughs.

Meanwhile, battery tech improvement rates are about 7% per year. Result, the 2017 Bolt EV has almost 7 times the range as the first year Volt. The Bolt is also priced the same as the 2011 Volt.

So when you account for inflation the 2017 Bolt is actually cheaper by about $3,500.

It does have 7X the range but it also has a 4X larger battery. LOL We really do need a breakthrough. There are so many advancements in the solid state area that I'm pretty hopeful at least one of them will work.

The larger battery was made possible by advancements in material technology and manufacturing techniques. Storage density and physical size are both improving. The Bolt has the space for the larger battery so why not make a physically larger battery with a higher energy density at the same cost as the smaller battery of the 2011 Volt.

The one thing I've noticed about all the solid state battery designs is they all need considerably more rare earths than LiOn for recharging. While this is great in the lab it makes these batteries far more expensive than LiOn to produce.
