“…For the anode pre‐lithiation additives, a high theoretical Li ion capacity and sufficient redox potential are required to avoid reducing the output voltage of the LIBs. The anode pre‐lithiation additives can be in various forms, such as stabilized lithium metal powder (SLMP), lithium alloy compounds and composites, etc., all of which have the above characteristics [56–63] …”

Lithium‐ion batteries (LIBs) are widely used as a new energy storage system with high energy density and long cycle life. However, the solid electrolyte interfacial (SEI) layer formed on the surface of anode consumes excess active lithium during the initial cycle, resulting in an initial irreversible capacity loss (ICL) and reducing the overall electrochemical performance. To solve the critical issue, pre‐lithiation technology has accepted as one of the most promising strategies. Due to the pre‐lithiated treatment provides additional active lithium to compensate for the ICL and effectively improves initial Coulombic efficiency (ICE), leading to raising the working voltage, increasing the Li+ concentration, as well as improving the energy density and cycle stability of LIBs. In this overview, the causes of ICL in LIBs are analyzed from different perspectives, and various pre‐lithiation strategies are systematically classified and summarized. Finally, some current problems and development prospects in this field are summarized, with prospects for realizing industrialized technologies.

“…Furthermore, recently, diphenyl ditelluride (DPDTe), as a redox mediator, was reported to accelerate redox kinetics for Li–S battery, in which Te radical‐mediated catalytic cycle at the solid–liquid interface contributed significantly to the whole process (Figure 2c). [ 44 ] The Li–S pouch cell with DPDTe delivered a high energy density of 336.1 Wh kg −1 (1322.1 mAh g −1 at 0.05 C), indicating successful application in practical condition. Overall, these works present a facile strategy of using organo‐chalcogenide molecules (same VIA group) as redox comediators.…”

Small organic chalcogenides molecules are receiving more attention in conjunction with the development of rechargeable lithium metal batteries (LMBs) especially lithium-sulfur (Li−S) batteries due to their abundant resources, reversible redox, high capacities, tunable structures, unique functional adjustability, and strong interaction with congener polysulfides. In this review, the working principles are generalized of small organo-chalcogenide molecules in three important parts of batteries: electrolyte, interface, and cathode. First, in terms of regulating kinetics in electrolyte, small organochalcogenide molecules can not only act as redox mediator to accelerate the redox kinetics of sulfur, but also change the inherently slow solid-solid process to form a faster redox pathway, which will bring light to the development of cryogenic Li−S batteries. Second, for interface chemistry, the introduction of small organo-chalcogenide molecules can construct more elastic and stable anodic single-SEI or cathodic/anodic dual-SEI, thus effectively improving the cycling stability of batteries. Third, small organo-chalcogenide molecules can be used as cathode materials in the form of liquid phase, solid phase, or precursor of polymers. Finally, advised optimizations are proposed about further mechanism deciphering, battery configuration design, machine learning, thereby providing direction to bridge the gap between rational modulation and practical battery implementation for small organochalcogenide molecules.

“…successfully synthesized synergistic catalysts comprising Mo 2 C and N‐doping as well as constructed a hierarchical spherical crosslinked conducting network to effectively decrease the potential of Li 2 C 2 O 4 to 4.16 V. The effect of prelithiation in stabilizing the SEI was confirmed through in situ X‐ray photoelectron spectroscopy (XPS) and energy spectrum.

The sufficient and reversible active lithium is the cornerstone for the operation of high‐energy lithium‐ion batteries. However, active lithium is inevitably depleted due to the formation of a solid electrolyte and the presence of irreversible side reactions. The shortage of lithium in optimally designed batteries not only leads to a depreciation of energy density but also deteriorates the electrode structure resulting in degradation of cycle life. Inspiringly, prelithiation technology that additionally compensates for lithium has been proposed and is playing an increasingly significant role in enhancing battery energy density and prolonging cycle life. Herein, guided by the factors that initiate lithium loss, the action mechanism and the effectiveness of prelithiation are scrutinized. Moreover, the emerging advanced prelithiation technologies based on anode/cathode materials, the key barriers, and the applicability at scale are systematically summarized and compared. Integrating the challenges and development trends aspires to provide a comprehensive prelithiated hybrid lithium replenishment and storage technology as a reference in the scale‐up of prelithiation technologies.
