    The growing integration of renewable energy sources into modern electricity systems has significantly increased the need for energy-storage technologies that are safe, sustainable, and cost-effective. Among the various alternatives under investigation, aqueous lithium-ion batteries (ALIBs) have emerged as a promising option due to their intrinsic safety, high ionic conductivity, environmental compatibility, and the use of non-flammable electrolytes. Nevertheless, their broader deployment remains constrained by the narrow electrochemical stability window of water and by the complex interfacial reactions occurring at the electrode–electrolyte interface. Lithium titanate (Li₄Ti₅O₁₂, LTO) has attracted considerable attention as an anode material for aqueous systems because of its exceptional structural stability, negligible volume change during lithiation and delithiation, and relatively high operating potential, which helps mitigate hydrogen evolution. This thesis presents a comprehensive literature-based study of LTO in ALIB configurations, examining synthesis approaches, structural and electrochemical characteristics, electrolyte design strategies, and electrode fabrication techniques.
