Abstract
Lithium-ion batteries (LIBs) represent a pivotal technology in the advancement of electric vehicles, driving the transition from traditional fuel-powered cars to more sustainable alternatives. The continuous demand for higher energy density in LIBs is essential for improving vehicle range, performance, and overall competitiveness in the automotive market. Central to this goal is the role of the electrolyte, which functions as a charge carrier within the battery's internal circuit. The electrolyte's properties directly impact the battery's ability to achieve higher energy densities. However, several challenges arise in optimizing electrolytes, including issues related to thermal stability, ionic conductivity, and compatibility with high-capacity electrodes. This paper delves into these critical challenges, analyzing the factors that currently hinder the achievement of ultimate energy density in LIBs. By exploring potential advancements in electrolyte design and formulation, this study provides insights into future strategies for enhancing the performance and energy density of LIBs, thereby supporting the broader adoption of electric vehicles.
