“…Several previous proposals clearly indicated that the use of a catalyst with carbon as an oxygen electrode material can effectively enhance the kinetics of the ORR and OER on the oxygen electrode in the Li-O 2 batteries. 33,34 Hence, the electrochemical properties of the Li-O 2 battery packed with the N 1 , N 2 , and N 3 based oxygen electrode were tested and compared with those of the KB electrode. The charge-discharge tests of assembled cell were carried out in the potential range of 2.0 -4.1 V at 30 • C with a current density of 0.4 mA cm −2 .…”

The electrochemical performance of lithium-oxygen batteries can be significantly improved by employing a suitable catalyst to enhance the oxygen reduction reaction (ORR) and oxygen evolution reaction (OER). Herein, a versatile, effective and economic co-precipitation synthesis of spinel NiCo 2 O 4 with an urchin-like structure has been reported as an electrocatalyst for rechargeable non-aqueous Li-O 2 batteries. The spherical urchin-like structure of spinel NiCo 2 O 4 was formed without the use of any template or surfactant. The oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) kinetics in the Li-O 2 batteries could be drastically improved by employing the effective NiCo 2 O 4 catalyst, achieving a higher discharge potential and rate. In particular, the urchin-like structure of the catalyst not only provides more electrocatalytic sites but also promotes mass transport in the electrolyte. In addition, mesoporous NiCo 2 O 4 can efficiently catalyze the formation and decomposition of Li 2 O 2 . The Li-O 2 battery containing the urchin-like NiCo 2 O 4 catalyst exhibited the highest specific capacity of about 7309 mA h g −1 at 0.2 mA cm −2 . The integrity and porosity of spinel NiCo 2 O 4 had a significant effect on the performance of the Li-O 2 battery with reasonable specific capacity and cyclability, suggesting that the NiCo 2 O 4 -based materials can be effective catalysts for oxygen electrode in high performance Li-O 2 batteries.Recently, Li-ion batteries (LIBs) have been the main energy storage media for portable electronic devices and electric vehicles/hybrid electric vehicles (EV/HEV). Unfortunately, the current LIBs can store only a limited amount of energy and are still relatively expensive. 1,2 In particular, to overcome the disadvantage of the insufficient energy density of LIB, a new battery chemistry with a higher energy density is needed. Recently, lithium-oxygen (Li-O 2 ) batteries have attracted much attention as a promising alternative to LIB for next generation electric vehicles, owing to their large theoretical energy density. 1,3-6 Among various types of Li-O 2 batteries, the non-aqueous system has achieved more encouraging results than other counterparts. 7,8 However, the stability and rate capability of the Li-O 2 battery need to be improved further for its commercialization. 5,9 The typical Li-O 2 cell consists of a porous oxygen electrode for the permeation of oxygen, an electrolyte containing a dissolved lithium salt, and a lithium metal electrode, which can greatly affect the capacity and durability of the cell. 10,11 In particular, the oxygen electrode and lithium electrode plays a crucial role in achieving high capacity and durability for the Li-O 2 battery and represent most serious challenge for the development of the battery. 6,12 Moreover, the large overpotential of the Li-O 2 battery is mainly attributed to the sluggish kinetics of the oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) on the oxygen electrode. In addition, the rechargeability of the ...

“…Recently much attention has been paid towards the development of efficient cathode catalysts, including precious metals, porous carbon-based materials, transition-metal oxides (e.g., perovskites, spinels, and pyrochlores), as potential candidates for bifunctional oxygen electrode in metal-air batteries [5][6][7][8][9][10][11][12]. Among them, perovskite-based materials have been intensively explored due to their fascinating physico-chemical properties, high electrochemical stability, cost-effectiveness, and environmental friendliness [13][14][15][16]. In the ABO 3 (A is a rare earth or alkaline earth metal and B is a transition metal) perovskite oxides, both physico-chemical and electrocatalytic properties can be tuned by the selection of the B-site cations (single or combination of multiple ions).…”

“…Among these candidates, perovskite oxides have attracted sustained scientific and technological interests due to their relatively high activities, attractive cost advantage, environmentally benign and so on. Their catalytic activities, ionic and electronic conductivities can be tailored by partially replacing the elements in either A-site (such as Sr and Ca) or B-site (such as Co, Ni, Fe, and Cu) [11]. For example, Co-and Mn-containing perovskites have been investigated for oxygen reduction [12][13][14].…”
