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.
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. Different structures, proportions, and forms of electrolytes become crucial under conditions conducive to Li-ions transport.
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.
In order to further verify the electrochemical performance of the designed Li 7.3 P 2.9 S 10.75 X 0.3 (X = F, Cl, Br, and I) electrolytes in all-solid-state batteries, we selected Li 7.3 P 2.9 S 10.75 I 0.3 with the highest ionic conductivity to fabricate all-solid-state lithium batteries.
Electrolyte conductivity ratio to thickness above 10 S m −2 is needed at C-rates>10. Diminishing returns predicted from further improvement of Al-LLZO conductivity. Solid-state batteries offer the potential to improve safety, cyclability, and energy density of Li-ion batteries. However, their conductivity, stability, and processing limit their use.
Different electrolytes (water-in-salt, polymer based, ionic liquid based) improve efficiency of lithium ion batteries. Among all other electrolytes, gel polymer electrolyte has high stability and conductivity. Lithium-ion battery technology is viable due to its high energy density and cyclic abilities.
