I remember a recent paper that found that charging at double the current, but at 2khz frequency square wave basically eliminated battery degradation.

There appear to be two recent papers on this phenomenon:

2021: low frequency pulsed charging: https://vbn.aau.dk/ws/portalfiles/portal/451327786/C5.pdf

2024: high frequency pulsed charging https://onlinelibrary.wiley.com/doi/10.1002/aenm.202400190

Not up to really reading them right now, but this is a pretty neat area of research!
