There are several important differences. The practical difference between Lithium batteries and Lithium-ion (Li-ion) batteries is that most Lithium batteries are not rechargeable but Li-ion batteries are rechargeable. From a chemical standpoint Lithium batteries use lithium in its pure metallic form. Li-ion batteries use lithium compounds which are much more stable than the elemental lithium used in lithium batteries. A lithium battery should never be recharged while lithium-ion batteries are designed to be recharged hundreds of times.

Lithium Ion batteries are able to hold a charge for many months. It is best to store a lithium-ion battery with a partial or full charge. If a lithium-ion battery with a very low charge is stored for a long period of time its voltage can drop below the level at which its built in safety mechanism allows it to be charged again. If the battery is going to be stored for several months it's a good idea to take it out and recharge it after a few months. It would be even better to actually use the battery every few months and then leave it partially or fully charged.

NiMH batteries do not have a "memory effect". However NiMH batteries can experience what is known as "voltage depression", similar to NiCd batteries, but the effect is generally less noticeable. To eliminate the possibility of NiMH batteries suffering voltage depression manufacturers recommend an occasional, complete discharge of NiMH batteries followed by a full recharge. NiMH batteries can also be damaged by overcharge and improper storage. Most users of NiMH batteries don't have to be concerned with this voltage depression effect, but if you use a device for only a short period of time every day, and then charge the batteries every night, you will need to let the NiMH batteries run down occasionally to keep this effect from occurring.

Smart batteries have internal circuit boards with smart chips that allow them to communicate with the host device and monitor battery performance. Dumb batteries will power the device, but lack the communication chip.
