Hi.
Those cheap garden lights with a single white LED and a single NiCd cell use a dedicated IC to operate.
The solar panel charges the cell by itself at daylight, but the cell voltage is to be raised to turn the LED on at darkness.
Would it be hackable ? Using/rewiring the circuitry of that same chip to raise the panel voltage to 4V for recharging the LiIon cell at daylight and operate the LED at night ?

In other words, how could those cheap garden lamps be fitted with a LiIon cell instead ?
Here is some data for a similar chip :
