Reusable Hybrid Battery
Reusable hybrid battery is a nickel hydride battery inside of hybrid batteries that powers the car when the gas engine is not on. The battery takes energy from the gas engine, stores it, and then, when needed, gives its power out to power the car.

Nickel Hydride Battery
Prius's now use a Nickel-metal hydride battery that is not good for the environment, because they do not last very long at all. nickel-metal hydride cell, abbreviated NiMH, is a type of secondary Electrochemical cell similar to nickel hydrogen cell. The NiMH battery uses a hydrogen-absorbing alloy for the negative electrode instead of cadmium. As in NiCd cells, the positive Electrode is nickel oxyhydroxide (NiOOH). A NiMH cell can have two to three times the capacity of an equivalent size Nickel-cadmium battery. However, compared to the lithium-ion cell, the volumetric Energy Density is lower and self-discharge is higher.These batteries are also very Flammable, and there have been some cases of nickel hydride batteries that have caught Fire in Flight, resulting in a Crash.

Lithium Ion
A more "green" solution to Prius batteries is a Lithium-ion battery or Li-ion batteries. Lithium-ion batteries (sometimes abbreviated Li-ion batteries) are a type of Rechargeable Battery in which lithium ions move from the negative electrode (anode) to the positive electrode (cathode) during discharge, and from the cathode to the anode during charge.

Lithium-ion batteries are common in portable consumer electronics because of their high energy-to-weight ratios, lack of memory effect, and slow self-discharge when not in use. In addition to consumer electronics, lithium-ion batteries are increasingly used in defense, automotive, and aerospace applications due to their high energy density. These batteries are also good because they are very light weight and that means that the prius will use less gas when driving.
