2020-08-24 Tesla Upcoming Battery Day

When there’s a huge solar energy spill,

It’s called A NICE DAY. 👍👍😆😆


This author thinks the upcoming Battery Day on Sep 22 will be a revelation of a revolution. Talks about nanowires and supercapacitors. One thing that crossed my mind is why haven’t the battery makers made the batteries like a stack of pancakes. Instead of rolling them up into cylinders. Maybe the cylinders allow easier cooling with air between the cylinders. The old 9V, 22.5V, 45V, etc.. ‘heavy duty’ batteries were made sort of like slices of a sandwich. If heat buildup in the center is a problem then they could put a hole through the center and run coolant through it.
