  1. The progress in batteries is crazy these past ten years. First twenty years of my life batteries weren't that crazy from each other. Then bam! Cell phones and then EVs sped up investments. CATL just said they have a battery with 10 years warranty at 600k miles. Supposedly has similar if not better density. If any degradation happens they'll replace it. That is a million kilometers with little maintenance. I've also read research saying a lot of batteries cap at 90% for newer batteries. Yet I myself wonder what charging method is used. I think any videos like this should focus on newer batteries, but from what I gather since we don't have info it is hard to judge some of the newer chemistries. Can't wait for certain battery techs to leave the lab. Even if you don't care for EVs battery tech is super important for a lot these days.

  2. I heard newer batteries are capping out at 90%. Also I've read we really don't have a lot of data on newer chemistries which makes sense. Yet the predictions are pretty good to me. CATL has a battery they say that will last ten years for 600k miles or a million kilometers. With modern power densities. If true that is crazy. Batteries aren't going to be the weak link eventually especially if solid state takes off. I hope. That is if you beleive what all the companies are saying. Lemme tell you I love how fast battery development is during my life. It seemed stagnant then boom the past ten years have been crazy. Even if you don't care about EVs the progress in batteries is a damn good thing which opens up so many things. Just waiting for lithium air chemistries to have a break through damn it. Being able to get the oxygen from the air looks amazing as far as theoretical power density goes. Something like 12,000 watts per KG at max therotical density. Even reaching half that would be game changing. WE could finally have exoskeletons!
