Tesla Acquires Canadian Battery Specialist, Hibar Systems
I have two questions regarding batteries I often wonder about. Maybe the wisdom of the HN crowd can answer one or both of them:<p>Is there a theoretical limit on how much energy a rechargeable battery of, say, 1 kg mass can hold?<p>Can a rechargeable battery be discharged and recharged and afterwards be in the same state it was before the cycle? Or is degradation inevitable? Again, I am asking for the theoretical possibility. Not real life challenges to implement it.
