Solar panel

An Li does not charge "faster" unless the Li will accept the charger's max amps, but the ordinary battery bank of the same AH size won't. Solar is generally a low amp business, with all day to recharge.

So any so-called "faster charging with Li" is not going to be realized with solar recharging. You would need a much higher amp recharge scenario to get any of that. A pair of flooded batts at 200AH at 50% can accept 60 amps no sweat. 60 amps means a lot of solar and would probably be at 60 only around lunchtime anyway.

There can be good reasons to have Li, but the "faster charging" claim needs to be very scenario specific.

If there is just one scenario that fits the bill of lfp being able to "faster charging " then it charges faster. I won't bother with my scenarios that would fill the batteries "faster" but then I'll take what ever charge the panels will produce but as fulltime boondocker living off of lfp & solar and being able to charge to 14.1v absorb instead of 14.6 or more that lead needs make a difference or accepting everything I can throw at it to 98-99% SOC where your lead slows way down much earlier in its SOC trying to absorb the charge. Isn't that faster?

One more thing I thought about is if I had to use the generator and solar to charge for fast charging which I have done once the batteries were being charged at 175a, that makes for a fast charge off grid.
