A lithium-ion battery or Li-ion battery (abbreviated as LIB) is a type of rechargeable battery, first proposed by chemist M Stanley Whittingham at Exxon in the 1970s. Today lithium-ion batteries are commonly used for portable electronics and electric vehicles and are growing in popularity for military and aerospace applications.
One of the most successful Li-ion systems is a cathode combination of nickel-manganese-cobalt (NMC). Also known as lithium-manganese-cobalt-oxide batteries, or NMC, lithium nickel manganese cobalt oxide batteries are made of several materials common in other lithium iron batteries. These involve a cathode combination of nickel, manganese and cobalt NMC in the same cell optimized for specific power has a capacity of only about 2,000mWh but delivers a continuous discharge current of 20A.
