Various parameters, such as ion conductivity, viscosity, dielectric constant, and ion transfer number, are desirable regardless of the battery type. The ionic conductivity of the electrolyte should be above 10 −3 S cm −1. Organic solvents combined with lithium salts form pathways for Li-ions transport during battery charging and discharging.
Finally, the state-of-the-art of the system is given and some interesting strategies for the future developments are illustrated. Abstract This paper presents an overview of the various types of lithium salts used to conduct Li+ ions in electrolyte solutions for lithium rechargeable batteries.
We report the conductivity of 150 non-aqueous electrolytes for rechargeable Li batteries between −60 and 80 °C. A wide range of solvents including esters, ethers, aromatics, chlorinated solvents, etc., and mixtures thereof, were studied. Results for five electrolyte salts which have some promise for rechargeable Li cells are presented.
These solvents are combined with lithium salts, such as LiPF 6 or LiBF 4, and the mixture also includes various additives. This combination is essential for the functioning of LIBs, providing the necessary components for energy storage and release during the LIBs’ operation .
Lithium salts exhibit heightened ionic conductivity and facilitate a prompt transport rate of lithium cations, thereby achieving elevated levels of power and ionic conductivity. The salts require a high degree of solubility in electrolyte solvents to yield a sufficient number of charge carriers for facilitating ionic conduction.
In advanced polymer-based solid-state lithium-ion batteries, gel polymer electrolytes have been used, which is a combination of both solid and polymeric electrolytes. The use of these electrolytes enhanced the battery performance and generated potential up to 5 V.
