“…Heteroatom doping has been wildly applied to the development of other electrocatalysts for energy conversion reactions. [ 155–158 ] The metal phosphide such as Ni 2 P has been demonstrated to be active catalysts for LiPSs conversion and since it receives a certain degree of cation dopants and disorder in the original crystallographic framework. The Co dopants in Ni 2 P (denoted Ni 2 Co 4 P 3 ) can raise the d‐band structure of metal sites and facilitate the interaction between catalyst and LiPSs, thereby decreasing the activation barrier of LiPSs conversion ( Figure 8 a).…”

The lithium–sulfur battery is regarded as one of the promising energy‐storage devices beyond lithium‐ion battery due to its overwhelming energy density. The aprotic Li–S electrochemistry is hampered by issues arising from the complex solid–liquid–solid conversion process. Recently, tremendous efforts have been made to optimize the electrochemical reaction in Li–S batteries through rationally designing compositions and structures of cathodes. However, a deep and comprehensive understanding of the actual mechanisms of Li–S batteries and their impact on the performance is still insufficient. The vigorous development of various electrochemical analysis and in situ techniques establish a bridge between the microstructure of components and the macroscopic electrochemical performance, thus providing more scientific guidance for the optimal design of Li–S batteries. In this review, based on insights into the mechanism of aprotic Li–S electrochemistry with the aid of in situ characterization and electrochemical methods, the advanced innovations in optimizing Li–S batteries are systematically summarized, including the materials design, cathode configurations optimization, and electrolyte engineering, with the aim to gain a comprehensive understanding of cathodic redox processes and thus achieve high‐performance Li–S batteries. The current status and possible future directions of the field are accordingly outlined.

“…Li 2 O 2 tend to convert to Li 2 CO 3 as a thermodynamically favorable process in presence of CO 2 according to their standard Gibbs free energies of formation. [ 57 ] Several studies have also confirmed the generation of Li 2 CO 3 because of the reaction between Li 2 O 2 , [ 44,58 ] O 2 − , [ 59,60 ] and CO 2 . The Li 2 CO 3 film acting as a passivating layer covers on the surface of cathode, which leads to large interfacial resistance [ 28 ] and impedes the growth of Li 2 O 2 .…”

is restricted to their inferior energy densities (≈250 Wh kg −1) due to intercalation chemistry. Consequently, "beyond Li-ion batteries" such as lithium-sulfur batteries and metal-air batteries, which have fundamental discrepant energy storage mechanism, have been attracted worldwide attention recently. [4,5] Of all the candidates, rechargeable lithium-oxygen battery (LOB) is considered to be one of the most fascinating next-generation batteries with extremely high theoretical energy density (≈3500 Wh kg −1). [6,7] The low-cost and environmental positive active material oxygen originates from air, endowing LOBs more attractive to satisfy the soaring demand of large-scale energy storage system. Generally, there are four architecture systems of LOBs determined by different electrolyte: aqueous, nonaqueous, hybrid, and all-solid-state. [8-11] In 1996, Abraham and Jiang first reported the rechargeable lithium-oxygen battery consisted of Li metal anode, solid polymer electrolyte membrane, and composite carbon cathode. [12] After ten years, nonaqueous LOBs actually caught worldwide attention due to the outstanding capacity and reversibility. [6] A typical nonaqueous lithium-oxygen battery comprises a metallic Li anode, organic electrolyte containing Li salt, a separator, and a porous gas diffusion cathode loading with catalysts (Figure 1). [13] Generally, the electrochemical reactions of nonaqueous lithium-oxygen battery can be described as following equations [14-16] Overall reaction E 2Li O Li O 2.96 V vs Li/Li 2 2 2 () + ↔°= + (1) Cathodic process (oxygen reduction reaction (ORR))

“…[ 81,82 ] Noble metals with intrinsic semi‐filled antibonding states can enhance the reaction kinetics through improving the interfacial interaction between different reactants. [ 83,84 ] In the case of Na‐O 2 batteries, various Pt nanoparticles grown on graphene nanosheets, [ 85 ] Ag nanoparticle‐decorated reduced graphene oxide, [ 86 ] micrometer‐sized RuO 2 , [ 87 ] RuO 2 nanoparticles dispersed on carbon nanotubes, [ 88 ] and Pd nanoparticles grown on ZnO‐coated graphitized carbon black [ 89 ] have all been adopted as oxygen cathode. In 2015, Yang’s group synthesized Pt nanoparticles that were in situ grown on graphene nanosheets (Pt@GNSs) through a traditional hydrothermal method as air cathode for the Na‐O 2 battery system.…”
