But one thing has held back solid-state batteries: Instabilities at the boundary between the solid electrolyte layer and the two electrodes on either side can dramatically shorten the lifetime of such batteries. Some studies have used special coatings to improve the bonding between the layers, but this adds the expense of extra coating steps in the fabrication process. Now, a team of researchers at MIT and Brookhaven National Laboratory have come up with a way of achieving results that equal or surpass the durability of the coated surfaces, but with no need for any coatings.
The new method simply requires eliminating any carbon dioxide present during a critical manufacturing step, called sintering, where the battery materials are heated to create bonding between the cathode and electrolyte layers, which are made of ceramic compounds. Even though the amount of carbon dioxide present is vanishingly small in air, measured in parts per million, its effects turn out to be dramatic and detrimental. Carrying out the sintering step in pure oxygen creates bonds that match the performance of the best coated surfaces, without that extra cost of the coating, the researchers say.
Doubling the range of electric vehicles would make them more practical. However, I remain skeptical of electric vehicles because of the cost. Seems like hybrids are the way to go.

This video shows the very well known "Monty Hall Problem". Monty Hall was the game show host of Let's Make a Deal. At the end of each show the winning contestant chose door #1, door #2, or door #3. So, if Monty Hall says there are goats behind 2 doors and the grand prize behind one door. So, let's say you pick door #1. Monty now says I'm going to help you by letting you know that door #3 has goats.So, speaking mathematically, should you keep your original pick of door #1. Or should you change your pick to door #2?Btw, normal IQ falls between 85 to 115.

New Study Finds COVID-19 DNA Linked to Moderna Patent Filed in 2016, Sparks Discussion on Lab Leak Theory
"So it doesn't mean very much, to be frank, if you do these types of searches, you can always find matches.
"Sometimes these things happen fortuitously, sometimes it's the result of convergent evolution (when organisms evolve independently to have similar traits to adapt to their environment).
"It's a quirky observation, but I wouldn't call it a smoking gun because it's too small.
"It doesn't get us any further with the debate about whether COVID-19 was engineered," Young said.
A statement from the US drug maker Moderna is awaited, the report said.
