Lithium-Ion Battery:— Rachid Yazami is one of the four inventors of the rechargeable lithium ion battery;[n. 1][1] a Morroccan Muslim,[2] who's technology was used in 8 billion batteries in 2012 alone.[3][n. 2] His specific contribution was the physical invention of the graphite anode (or, the negative electrode) that allowed the battery to recharge multiple times.[3][4] The electrochemical properties of lithium and graphite were discovered by him in 1980 where he found lithium intercalated with graphite,[5] and by 1991, Japanese technology company, Sony, released the first consumer produced lithium ion batteries using his technology.[5] Yazami's technology is still relevent today, as his invention is vital for future battery nanotechnology, chiefly for the purposes that nanomaterials offer larger surface areas, short electron transport lengths, high reversible capacities and long life cycles.[5] Every year approximately 6 billion lithium ion batteries are sold, representing about 40% of all cell sales.[6] By 2020, the batteries will become so important that they will be worth $22 billion dollars alone for the car industry.[6] Lithium-ion batteries are currently one of three rechargeable batteries used today, the others being Nickel-Cadmium (NiCd) and Nickel-metal Hydride (NiMH), however Li-ion dominate growth.[n. 3][n. 4] Yazami also invented a smart chip that can charge cell phone batteries fully in 10 minutes by using sensors in 2015.[7]

[7] Yazami discovered the graphite anode, which is crucial to Li-ion batteries. Yazami's technology also made lithium ion batteries extremely safe to recharge as well, leading to their widespread success.
