I've been told that my blog posts are very long. I have been known to retort that no one reads anything anymore. After a few years of going back and forth on this I have come to the conclusion that if you can't best them, join them.
Research (an euphemism for "made up") suggests that the human brain can't take more than 140 characters. So here goes. A summary of batteries in a dozen bite-sized tweets:
Guess which battery will power most phones, EVs, and home solar in 2025? A lithium battery. Yes. Really. Good luck new chemistries.

A battery fire is a feature�in Antarctica. For the rest, so wish we had new chemistries. Water, where art thou? Hate flammable electrolytes.
Lead-acid (yes, that old dog), will destroy Li-ion for grid storage. Oh ya� there is that sulfation thing to solve.
The 2017 Li-ion battery is not your grandfathers one. It is oh, so different on the inside. Don�t judge a book by its cover.
Is there a solid-state battery in your EV future? Not unless you are less than 50 years old (assumption: life expectancy=70). I made it.
EV battery roadmap: High voltage then silicon, then Li metal, sulfur, (oxygen?), Mg (Al?). After that? Aliens tech. Or maybe fluorine.
Grid battery roadmap: Li-ion or lead-acid or flow or sodium or Zinc or... Who knows. Confused? So is everyone else. Except the aliens.
Hear about an amazing breakthrough in batteries? Safely ignore it. The inventors did when they violated a few laws of nature.
All battery companies will claim to drive cost to less than $100/kWh sometime in the future. Even if they make the battery out of solid gold.
Performance of any battery will fall (just) short of expectations irrespective of the complexity of the device it is powering.
Pull the plug. Your battery will thank you. And don�t use the wrong rules for the wrong battery. Memory effect is so 1995.
It takes 10 years and $250M to start a battery company. Unless you are in China. Then it takes 1 year and $50M. Gotta love incentives.
