The development of MABs has, however, been considerably hampered by its relatively low rate capability and its lack of efcient and stable air catalysts in which the former stems mainly from the sluggish kinetics of the oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) and the latter stems from the corrosion/oxidation of carbon materials in the presence of oxygen and high electrode potentials. In this review, various carbon-composited bifunctional electrocatalysts are reviewed to summarize progresses in the enhancement of ORR/OER and durability induced by the synergistic efects between carbon and other component(s). Catalyst mechanisms of the reaction processes and associated performance enhancements as well as technical challenges hindering commercialization are also analyzed. To facilitate further research and development, several research directions for overcoming these challenges are also proposed.

Multivalent batteries are also supposed as the potential candidates to Li-ion batteries in portable electronic devices and large-scale energy storage units. Unfortunately, most commercial cathode materials in Li-ion batteries cannot be applied in multivalent batteries because of the intensive polarization problem of multivalent intercalated ions (Mg2+, Zn2+, Al3+). Choosing and synthesizing the appropriate cathode materials are the main issues in overcoming the intensive polarization problem. Vanadium-based materials often possess many kinds of oxidation states because of the mutable vanadium element, which can facilitate achieving local electroneutrality and relieve the polarization problem of multivalent ions. In this review, we summarize the researches about the vanadium-based cathode materials for multivalent batteries and highlight the intercalation mechanism of multivalent ions to vanadium-based materials. In addition, diferent kinds of optimizing strategies are extracted from the literatures. On the basis of our review, progresses and future challenges of vanadium-based cathode materials in rechargeable multivalent batteries are more explicit.

However, despite recent progress toward practical application, commercial TCM-based lithium ion batteries (LIBs) sufer from severe issues such as the use of fammable and hazardous electrolytes, with one high profle example being the ignition of NCA-based LIBs used in Tesla Model S vehicles after accidents, which jeopardizes the future development of TCM-based LBs. Here, the need for TCM and fammable liquid electrolytes in TCM-based LBs is a major obstacle that needs to be overcome, in which conficting requirements for energy density and safety in practical application need to be resolved. To address this, polymer electrolytes have been demonstrated to be a promising solution and thus far, many polymer electrolytes have been developed for high-performance TCM-based LBs.

This is because LLOs possess maximum possible capacities of~280 to 310 mAh g-1 with a high working potential of~3.7 V (vs. Li+/Li0) and an astounding energy density of~900 Wh kg-1. Despite these promising properties, these technologically important cathodes have not yet been successfully commercialized due to low initial Coulombic efciency, poor rate capabilities and gradual capacity/voltage fade during electrochemical cycling as well as further complications from continuous structural changes during cycling. Here, researchers have concluded that these issues mainly originate from the electrochemical activation of Li2MnO3 components, which, although it provides anomalously high capacity performances, also causes associated complex anionic redox activities of O and irreversible structural and phase transformations during charging at potentials greater than 4.5 V (vs. Li+/Li0). To provide perspectives, this review will summarize various attempts made towards addressing these issues and present the connections between electrochemical properties and structural change. In addition, this review will discuss redox chemistries and mechanistic behaviours during cycling and will provide future research directions to guide the commercialization of LLOs.
