SECONDARY BATTERIES – METAL-AIR SYSTEMS | Bifunctional Oxygen Electrodes

Multifunctional Electrocatalysis on Single-Site Metal Catalysts: A Computational Perspective

“…The CHE model assumes the following: (1) The interface is in equilibrium with the electrode and electrolyte; (2) The energy of the model is independent of the electrostatic field and boundary conditions. More generally, the interface must be charge neutral and large enough to screen all charges.…”

“…Eventually, from an energy storage perspective, the amount of energy stored in secondary batteries is directly related to the extent of active masses in the battery. Using oxygen as an active component at the positive electrode is a viable option since oxygen is a part of the atmospheric gases and does not increase the battery mass [2]. ORR is the key reaction in the secondary batteries in the discharge mode, while OER applies to the charging process of secondary batteries relying on oxygen electrodes.…”

Effect of Na₂SO₄ on the Performance of Mg-Air Battery

“…One of the potential systems is metal-air battery which shows great potential in electronics, stationary and automotive applications [4]. Magnesium is a superior anode material for metal-air battery due to its high theoretical specific discharge capacity, low electrode potential, rich reserves and low cost [5,6]. However, the poor performance of the air electrode limited the development and commercial exploitation of Mg-air battery.…”

Post-lithium-ion battery chemistries for hybrid electric vehicles and battery electric vehicles

“…Bifunctional catalysts are useful for both oxygen reduction and evolution (Jörissen, 2009). A key point of future development is a mesoporous carbon cathode, and a membrane to prevent the CO 2 and moisture migration into the air electrode while allowing O 2 diffusion and mass transport.…”
