All hybrids still have lead acid batteries, but most - not all - hybrids have nickel-metal hydride batteries to assist in fuel savings and lower emissions. The nickel-metal hydride battery (NiMH) is an integral part of a hybrid system.
A nickel-metal hydride battery (abbreviated NiMH) is a type of rechargeable battery similar to a nickel-cadmium (NiCd) battery, but has a hydride absorbing alloy for the anode instead of cadmium, which is an environmental hazard; therefore, it is less detrimental to the environment. Applications of NiMH type batteries includes hybrid vehicles such as the Honda Insight and Toyota Prius.
Lithium ion batteries (sometimes abbreviated Li-Ion) are a type of rechargeable battery commonly used in consumer electronics. They are currently one of the most popular types of battery, with one of the best energy-to-weight ratios, no memory effect and a slow loss of charge when not in use. Lithium ion battery applications have the potential of eclipsing the NiMH battery in hybrid vehicles; compared to a lithium ion battery, the NiMH battery's volumetric energy density (amount of potential energy stored in the battery) is lower and self-discharge is higher. However, they can be dangerous if mistreated, and may have a shorter lifespan compared to other battery types.
