9 High-Temperature Lithium Rechargeable Battery Cells

Because ionic liquids (ILs) consist only of ions, they offer two brilliant features very high concentration of ions [1] and high mobiUty of component ions at room temperature. Because many ILs show the ionic conductivity of over 10 S cm at room temperature [2, 3], there are plenty of possible applications as electrolyte materials, among these, for rechargeable lithium-ion batteries [4—8], fuel cells [9-12], solar cells [13-17], and capacitors [18-23],... 

One promising line of approach has been the development of rechargeable batteries that use an alkali metal (lithium or sodium) as the anode and sulfur as the electron acceptor. Sulfur is a nonconductor of electricity, so graphite is used as the cathode that conducts electrons to it. The elements must be in their liquid states, so these batteries are high-temperature cells (sulfur melts at 112°C, lithium at...
