Lion

n. species of large carnivorous cat found in Africa and southern Asia; strong and courageous person; celebrity, person who is well-known and admired

The lion (Panthera leo) is a member of the family Felidae and one of four "big cats" in the genus Panthera. Reaching 272 kg (600 lb), it is the second-largest cat after the tiger. They currently exist in the wild in sub-Saharan Africa and in Asia with a critically endangered remnant population in northwest India, having disappeared from North Africa, the Middle East and western Asia in historic times. Until the late Pleistocene (about 10,000 years ago), the lion was the most widespread large land mammal beside man. They were found in most of Africa, much of Eurasia from western Europe to India and the Bering land bridge and in the Americas from Yukon to Peru.

Lithium-ion batteries (sometimes abbreviated Li-ion batteries) are a type of rechargeable battery commonly used in consumer electronics. They are currently one of the most popular types of battery for portable electronics, with one of the best energy-to-weight ratios, no memory effect, and a slow loss of charge when not in use. They can be dangerous if mistreated and unless care is taken their lifespan may be reduced. Although originally intended for consumer electronics, Lithium-ion batteries are growing in popularity with the defense and aerospace industries because of their high energy density.

(n.)
A large carnivorous feline mammal (Felis leo), found in Southern Asia and in most parts of Africa, distinct varieties occurring in the different countries. The adult male, in most varieties, has a thick mane of long shaggy hair that adds to his apparent size, which is less than that of the largest tigers. The length, however, is sometimes eleven feet to the base of the tail. The color is a tawny yellow or yellowish brown; the mane is darker, and the terminal tuft of the tail is black. In one variety, called the maneless lion, the male has only a slight mane.
