The lithium-ion battery (LIB) was first introduced in the market by Sony in 1991 and A&T Battery in 1992 [1] to power new portable electronics tools. The first generation of LIBs used a LiCoO 2based cathode and a carbonaceous anode, meeting the main requirements for portable electronics, i.e., gravimetric volumetric and energy densities at around 100 Wh kg À1 and 250 Wh dm À3 , respectively, as well as safety. [2] In just 10 years, LIBs reached a market share of 95% with about 10 GWh of installed energy and a corresponding business of about 10$ billion per year. [3] Later, the introduction of new alternative chemistries (LiMn 2 O 4 , LiFePO 4 , graphite) [4] and the optimization of the battery pack brought the energy density to over 200 Wh kg À1 and 350 Wh dm À3 . These improvements led to the implementation of LIBs in the automotive sector, [5] where their actual impact in the electrical vehicles (EV) market has been growing exponentially in the past years, [3] and it is driving the continuous and renewed interest toward rechargeable batteries. The future of LIBs, indeed, seems even more brilliant and analysts agree that the penetration of LIBs in the automotive market will lead to an estimated demand >500 GWh energy production in 2025 and >2000 GWh by 2030 (Figure 1a) at the compound annual growth rate (CAGR) of 30% in the next decade. [6] The success of LIBs is also favored by cost reduction, which in turn accelerates their penetration into the automotive industry.
