The development of ( a) anode materials including lithium metal, petroleum coke and graphite, ( b) electrolytes with the solvent propylene carbonate (PC), a mixture of ethylene carbonate (EC) and at least one linear carbonate selected from dimethyl carbonate (DMC), diethyl carbonate (DEC), ethyl methyl carbonate (EMC) and many additives, ( c) cathode materials including conversion-type materials, intercalation materials titanium disulfide (TiS 2) and lithium cobalt oxide (LiCoO 2). Milestone discoveries that shaped the modern lithium-ion batteries. It is this shuttling process or what is called rocking-chair chemistry that has revolutionized our modern life. ![]() During discharging, these ions move back to the CoO 2 host framework, while electrons are released to the external circuit. During charging, Li-ions move from the LiCoO 2 lattice structure to the anode side to form lithiated graphite (LiC 6). A modern lithium-ion battery consists of two electrodes, typically lithium cobalt oxide (LiCoO 2) cathode and graphite (C 6) anode, separated by a porous separator immersed in a non-aqueous liquid electrolyte using LiPF 6 in a mixture of ethylene carbonate (EC) and at least one linear carbonate selected from dimethyl carbonate (DMC), diethyl carbonate (DEC), ethyl methyl carbonate (EMC) and many additives. They also have a key role to play in enabling deeper penetration of intermittent renewable energy sources in power systems for a more sustainable future. The rechargeable lithium-ion batteries have transformed portable electronics and are the technology of choice for electric vehicles.
