And yet we have somehow gone from rechargeable phone batteries that were about 3 times bigger than the phone I’m typing this on and had a capacity of about 500 mAh to where we are now with the battery that powers my phone being some small part of it and having a capacity of 3000 may, with only two major technology changes on the way. Meanwhile, we’ve been using the same technology for over a decade and the capability keeps getting better. I wonder why that is?
