Improved Wide-Temperature Electrolytes for Li-ion Batteries using Sulfone Eutectic Mixtures
Background Lithium-ion batteries (LIBs) exhibit high energy and power densities, and thus are used in widespread applications including powering devices such as laptops and cell phones, to more recent applications such as electric cars. However, LIBs suffer from several issues when used at relatively high or low temperatures, mostly due to the nature...

A High Temperature-Stable Derivative of Anhydrous Phosphoric Acid
Hydrogen-oxygen fuel cells require an electrolyte that allows positively charged ions to pass from the anode to the cathode. Phosphoric acid is used in either liquid or membrane forms as an electrolyte and is stable to temperatures of 160°C. Above that temperature the compound breaks down causing loss of conductivity. Higher operating temperatures...

A new class of fast alkali ion conductor: Inorganic plastic crystals
Batteries operate by polarizing and transferring ions through liquid or molecular solvents. Recent developments have made use of organic cation salts in plastic crystalline states as solvents, in which lithium salts can be dissolved. These lithium salts are known as electrolytes. Unfortunately, they are associated with low conductivity. Other electrolytes...
