2. Lithium-Ion Batteries Operating Principle The failure of lithium-ion batteries (LIBs) is primarily attributed to three main aspects: the nature of the materials used, the rigor in design and manufacturing, and finally, the influence of the operating environment.
Pioneering works and detailed research by Prof. Goodenough and Prof. Dahn established layered Lithium Cobalt Oxide (LiCoO 2 or LCO) as one of the best choices for high-energy LIB electrode materials , , , , , . The history of LCO can be traced back to the 1980s when Prof. Goodenough's team utilized it as a cathode in a LIB.
The excess lithium is assumed to replace cobalt resulting in anti-sites L i ″ Co with charge compensation by oxygen vacancies V O, . Oxygen treatment removes oxygen vacancies from the lattice and improves capacity reversibility .
Fig. 4. Degradation as observed in discharge curves (left) and major causes for degradation of Li-ion batteries (right, EL denotes electrolyte). Side reactions at internal and external interfaces play a major role for degradation, resulting in loss of free lithium and impedance increase.
This phenomenon can stem from various degradation mechanisms, such as lithium plating/dendrite formation, binder decomposition, corrosion of the current collector, electrode particle cracking, structural disordering, and transition metal dissolution [50, 51, 52].
