I am assuming since you are comparing AA Alkaline to AA Li-ion batteries.
If so, these won't be a suitable substitute for your camera.
Rechargeable Lithium-ion batteries are a different chemistry from non-rechargeable Lithium (Lithium Iron Disulfide) batteries, which can confuse a lot of people.
Li-ion AA batteries have a voltage of 3.6V per cell, whereas typical AA batteries (Alkaline, non-rechargeable Lithium) batteries are 1.5V ( or 1.25V in the case of NiMh). If you put a set of 4 Li-ion AA batteries in your camera, you risk damaging it.
However, most camera rechargeable battery packs these days are Li-ion, but the camera and battery packs are designed to work together.
In general terms, Li-ion batteries are the best rechargeable batteries. Unfortunately, if your camera does not have a Li-ion battery pack, it cannot use them.
If your camera uses AA batteries, there are generally three different batteries you can use; Alkaline and Lithium (Lithium Iron Disulfide), which are non-rechargeable, and NiMH, which are rechargeable.
But there is a caution. The characteristics of the three battery types are different enough that the camera may or may not be able to efficiently use a particular type. Most cameras that allow the use of the three types have a setting in the menu to allow you to set up the camera for that battery. You will have to check your owner's manual for sure.
Lastly, some cameras may not be able to use NiMH batteries. Compared to Alkaline and Lithium batteries, NiMH batteries cannot supply as much current as the other two. This is different than capacity. Capacity is the amount of energy stored in the battery, while the current is how much of that energy can be supplied at any one time.
Your owner's manual should tell you if you can use NiMH batteries or not. Many owner's manuals also have a chart depicting how many photos you can take with each battery type. That way, you can determine which battery is most cost effective in your situation.
I am supplying a link to an article I wrote on AA batteries. While the article provides a recommendation on powering portable electronics found on a boat, it is generic enough to apply to camera gear.
