Scientists make surprising finding that all electric vehicle drivers should hear: 'Has been largely overlooked until now'

South Korean scientists decided to study the process of charge depletion in batteries. Surprising them were the effects of running your battery down to near depletion and found damage to the cathode. The damage is caused by oxygen combining to lithium, forming lithium oxide, at around 3 volts. This then causes the cell to swell when interacting with the electrolyte. This effect seems to be exacerbated in nickel enriched lithium batteries, like NMC (Nickel Manganese Cobalt) or NCA (Nickel Cobalt Aluminum) more so than others, like LMO (Lithium Manganese Oxide) or LFP (LiFePO4 - Lithium iron phosphate).

For those who want details, like me or @bwilson4web here’s the original study:...

A proposal in the big bill is to start annual federal fees on cars. $200 for EVs, $100 for hybrids, and $20 on all others. The last won't start until 2031, but the rest are immediate.
