The other main batteries that could be used for the same thing are much heavier. Lithium ion batteries high capacity is due to the material that they are made of. Lithium ion batteries do not suffer from a high discharge rate and are very practical for storing energy efficiently as well.
If you are going to be going to the store to check out what is available, it is best to be prepared ahead of time. You should familiarize yourself with common trends for each type of tool you need and then figure out what features are the best fit for your situation.

There are some concerns when it comes to these high powered batteries and how good they are for the environment. But all hybrid batteries are set to be recycled (Toyota has a $200 bounty on each Lithium battery stocks pack), and so unlike some lead batteries from conventional cars, they shouldn't end up in landfills.
OLithium-ion Batteries: these are the newest type of cell phone battery and, while having certain advantages over the older NIMH and NICD batteries, care must still be taken to ensure they perform at their best. For example, a new Lithium mines Ontario-ion battery should be "conditioned". What this basically means is that for the battery's first three charge cycles, fully charge the battery overnight and allow it to fully discharge before charging it again. This will increase the life and effectiveness of the cell phone battery.
Most automakers would like to see Lithium-Ion battery packs (you probably have a Li-Ion battery in your cell phone) which can store more energy. But as of right now, they are still too volatile/unreliable when placed in large packs for major carmakers to use. But that should be changing in the next few years. Both GM (with their Plug-In Saturn Vue) and Toyota (next generation Prius/ Hybrid Systems) believe the next generation of hybrids will come with Li-Ion battery packs.
Another one of the best drills out there is the Panasonic EY7540LN2L model. It makes fastening jobs a cinch. It is lightweight, and ergonomic. It is extremely easy on the wrist and hands, so it is comfortable to use. It has long lasting lithium batteries for longer jobs. It is an impact driver, and is definitely versatile. It costs more than the other two drills, but it is still one of the best. Overall, any of the drills mentioned above would be a great cordless drill to own.
