Lithium-ion batteries constitute the primary energy source in modern electric vehicles however their long-term degradation represents a fundamental challenge in electrochemical energy-storage research. Temperature extremes such as intense summer heat or severe winter cold can intensify electrochemical degradation, hasten performance decline, and shorten battery life. Recognizing that Uzbekistan exhibits a wide temperature range throughout the year, this study concentrates on the specific impacts of the country’s climatic conditions on battery aging, vehicle reliability, and long-term operational costs. First, the internal aging mechanisms of lithium-ion batteries are reviewed with respect to various anode and cathode chemistries to provide a clearer understanding of capacity fade and performance deterioration. Subsequently, key influencing factors particularly temperature-driven effects on battery life are examined in detail to identify pathways for improving long-term performance. Finally, acknowledging the distinctions between cell-level and system-level behavior, the degradation mechanisms of complete battery systems are analyzed.
