High energy and power density Lithium is a highly reactive element, meaning that a lot of energy can be stored in its atomic bonds, which translates into high energy density for lithium-ion batteries. Hence, it can be used in adequate sizes for applications from portable electronic devices, smartphones, to electric vehicles.

‘Lithium-based batteries’ refers to Li ion and lithium metal batteries. The former employ graphite as the negative electrode 1, while the latter use lithium metal and potentially could double the cell energy of state-of-the-art Li ion batteries 2.
As a result of global research and development efforts, several classes of nanostructured materials, including lithium metal oxides, chalcogenides, silicates and phosphates, with different chemical compositions, crystal structures, and higher surface/volume ratios have been revealed to provide additional sites for Li storage.
The Li isotope compositions of lithium deposits are related to the physicochemical conditions of ore-forming processes; differences in their genesis lead to higher δ 7 Li values for brines (+7.9 to +11.3‰ and +16.1 to +31.4‰) than for hard-rock deposits (−0.3 to +6.0‰).
The thermodynamic open circuit voltages (OCV) and lithium stoichiometry in the electrode are obtained using galvanostatic intermittent titration technique (GITT) in half cell and three-electrode full cell configurations. The activation energy and exchange current coefficient through electrochemical impedance spectroscopy (EIS) measurements.

The catastrophic consequences of cascading thermal runaway events on lithium-ion battery (LIB) packs have been well recognised and studied. In underground coal mining occupations, the design enclosure for LIB packs is generally constructed to be explosion-proof (IEC60079.1 Standard).
The proliferation of spent lithium-ion batteries (LIBs) is a growing concern in the expanding electric vehicles (EVs) market. Recycling spent ternary LIBs significantly relieves environmental pressure and reduces resource waste. In this study, a reduction roasting-leaching process utilizing graphite was present to selectively recover lithium from spent ternary LIBs cathode.
