“…Recently, Li 5 V 2 (PO 4 ) 3 is proposed as a novel cathode material and extra Li donor as shown in Figure 5B,C. [ 75 ] Two Li per formula unit is given to the Li 3 V 2 (PO 4 ) 3 and form Li 5 V 2 (PO 4 ) 3 by the electrochemical method using half‐cell configuration, and then the Li 5 V 2 (PO 4 ) 3 can be directly used as cathode materials to lithiated the anode and turn to Li 3 V 2 (PO 4 ) 3 as well. In this method, the lithiation degree can be readily controlled based on the potential after pre‐lithiation.…”

Next‐generation Li‐ion batteries (LIBs) with higher energy density adopt some novel anode materials, which generally have the potential to exhibit higher capacity, superior rate performance as well as better cycling durability than conventional graphite anode, while on the other hand always suffer from larger active lithium loss (ALL) in the first several cycles. During the last two decades, various pre‐lithiation strategies are developed to mitigate the initial ALL by presetting the extra Li sources to effectively improve the first Coulombic efficiency and thus achieve higher energy density as well as better cyclability. In this progress report, the origin of the huge initial ALL of the anode and its effect on the performance of full cells are first illustrated in theory. Then, various pre‐lithiation strategies to resolve these issues are summarized, classified, and compared in detail. Moreover, the research progress of pre‐lithiation strategies for the representative electrochemical systems are carefully reviewed. Finally, the current challenges and future perspectives are particularly analyzed and outlooked. This progress report aims to bring up new insights to reassess the significance of pre‐lithiation strategies and offer a guideline for the research directions tailored for different applications based on the proposed pre‐lithiation strategies summaries and comparisons.

“…Song et al proposed the Li 5 V 2 (PO 4 ) 3 (L5VP) cathode to prelithiate a HC anode based on a “giving comes before receiving” strategy ( Figure a). [ 112 ] It is noteworthy that the L5VP cathode is first obtained by lithiating Li 3 V 2 (PO 4 ) 3 (L3VP) as the “giving” step and the irreversible capacity loss of HC anode could be entirely compensated by de‐lithiation of L5VP called “receiving.” It is clearly observed that the two Li per formula of L5VP are extracted below the electrode potential of ≈3.0 V (versus Li/Li + ) for the L5VP//HC full cell, which could completely compensate the irreversible Li loss of HC anode (Figure 9b,c). Moreover, the average potential of HC anode is also decreased from ≈0.70 V for L3VP//HC full cell to ≈0.45 V (versus Li/Li + ) for L5VP//HC full cell.…”

Prelithiation/presodiation techniques are regarded as indispensable procedures in electrochemical energy storage (EES) systems, which can effectively compensate irreversible capacity loss, raise working voltage, and increase Li+/Na+ concentration in the electrolyte. Various prelithiation/presodiation methods have been successfully exploited and a revolutionary impact has been achieved through the utilization of prelithiation/presodiation techniques. It is well acknowledged that different prelithiation/presodiation strategies possess their own specific mechanisms, which play vital roles in the advancement of EES systems. However, there has rarely been systematical reviews about the concept and progress of prelithiation/presodiation techniques. Hence, in this review various prelithiation/presodiation approaches are comprehensively analyzed and summarized, and in‐depth prelithiation/presodiation behaviors and other innovative applications (including optimization of separators, amelioration of binders, regeneration of spent batteries) are discussed in detail. Finally, suggested future directions of prelithiation/presodiation techniques are proposed and it is expected that these prelithiation/presodiation techniques could provide guidance for construction of advanced EES systems and propel the commercialization process with a focus on safety considerations.

“…In addition to the layered metal oxide cathode, typical phosphate cathode Li 3 V 2 (PO 4 ) 3 (L3VP) has high stability between LiV 2 (PO 4 ) 3 (LVP) and L3VP with two voltage plateaus at 3.6 and 4.0 V. The L3VP could also undergo reversible phase transition between Li 5 V 2 (PO 4 ) 3 (L5VP) and L3VP, endowing an opportunity for extra prelithiation. [114] Two lithium ions in each formula of L5VP directly compensate for the lithium consumption of SEI and other side reactions on HC anode. The ICE of HC j j L5VP pouch cell is 96.7 % at 0.2 C, while that of HC j j L3VP is 62.6 %, and the average voltage of L5VP full-cell was also increased, thus the energy density of the L5VP full-cell was improved (Figure 6F).…”

Lithium-ion batteries (LIBs) have been widely employed in energy-storage applications owing to the relatively higher energy density and longer cycling life. However, they still need further improvement especially on the energy density to satisfy the increasing demands on the market. In this respect, the irreversible capacity loss (ICL) in the initial cycle is a critical challenge due to the lithium loss during the formation of solid electrolyte interphase (SEI) layer on the anode surface. The strategy of prelithiation was then proposed to compensate for the ICL in the anode and recover the energy density. Here, various methods of the prelithiation are summarized and classified according to the basic working mechanism. Further, considering the critical importance and promising progress of prelithiation in both fundamental research and real applications, this Review article is intended to discuss the considerations involved in the selection of prelithiation reagents/strategies and the electrochemical performance in full-cells. Moreover, insights are provided regarding the practical application prospects and the challenges that still need to be addressed.
