Abstract:
NaCl-assisted annealing creates defect-rich Fe-Nx environments and renders Fe centres more electron deficient in Fe-NC. The resulting catalyst reaches an ORR half-wave potential of 0.89 V vs. RHE and enables zinc-air battery cycling beyond 2200 h. Spectroscopy and DFT attribute the enhancement to weakened *OH adsorption.

Electrolysis
In a galvanic cell, the electrical work is done by a redox system on its surroundings as electrons produced by the spontaneous redox reactions are transferred through an external circuit. Alternatively, an external circuit does work on a redox system by imposing a voltage sufficient to drive an otherwise nonspontaneous reaction in a process known as electrolysis. For instance, recharging a battery involves the use of an external power source to drive the spontaneous (discharge) cell reaction in...
Batteries and Fuel Cells
A battery is a galvanic cell that is used as a source of electrical power for specific applications. Modern batteries exist in a multitude of forms to accommodate various applications, from tiny button batteries such as those that power wristwatches to the very large batteries used to supply backup energy to municipal power grids. Some batteries are designed for single-use applications and cannot be recharged (primary cells), while others are based on conveniently reversible cell reactions that...
