We present theoretical analysis on why and how rechargeable metal–air type batteries can be made significantly safer and more practical by utilizing CO2/oxalate conversions instead of O2/peroxide or O2/hydroxide ones, in the positive electrode. Metal–air batteries, such as the Li–air one, may have very large energy densities, comparable to that of gasoline, theoretically allowing for long range all-electric vehicles. There are, however, still significant challenges, especially related to the…

Investigation of the O2 electrochemistry in a polymer electrolyte solid-state cell.
Herein the authors depart totally from this conventional approach by moving to a solid-state cell using a poly(ethylene oxide)–lithium triflate (PEOLiCF3SO3) solvent-free polymer electrolyte, to assure a cell structure in which reactions of the products of the electrochemical process (and, particularly, of the singlet oxygen) with electrolyte could be totally avoided.

Implications of CO2 Contamination in Rechargeable Nonaqueous Li-O2 Batteries.
The results emphasize the importance of not only completely removing CO2 from air fed to a Li-air battery, but also developing stable cathodes and electrolytes that will not decompose during battery operation to form carbonate deposits.
Rechargeable LI2O2 electrode for lithium batteries.
Two essential prerequisites for the successful operation of a rechargeable Li/O(2) battery are demonstrated; that the Li(2)(2)O( 2) formed on discharging such an O(2), and that charge/discharge cycling is sustainable for many cycles.

A reversible long-life lithium-air battery in ambient air.
This work replaces easily decomposable liquid electrolytes with a solid Li-ion conductor, which acts as both a catholyte and a Li protector, and replaces conventional solid air cathodes with a gel cathode, which contacts directly with the solid catholytes to form a closed and sustainable gel/solid interface.
Electrocatalytic CO2 Conversion to Oxalate by a Copper Complex
A dinuclear Copper(I) complex that is oxidized in air by CO2 rather than O2 is described; the product is a tetranuclear copper(II) complex containing two bridging CO2-derived oxalate groups, which can be nearly quantitatively electrochemically reduced at a relatively accessible potential, regenerating the initial dinuclear copper (I) compound.
