Chemistry Scientists developed a new lithium-sulphur battery with a capacity five times higher than that of lithium-ion batteries, which maintains an efficiency of 99% for more than 200 cycles, and may keep a smartphone charged for five days. It could lead to cheaper electric cars and grid energy storage.

Nah, just the activity of charging above 80% wears more than the charging the lower full 80% 'cycle'.

Storage is even another thing.

I believe Elon said if you have to charge to 100%, don't leave it for long. Try to time it to ride right when it hits 100%.

But I don't think it's something he recommends doing on a regular basis.
