Lithium nitrate (LiNO 3 ) as an effective additive to construct stable solid electrolyte interface (SEI) is generally applied in ether-based electrolytes, but its poor solubility in carbonate-based electrolytes limits further application for Li metal batteries (LMBs). Therefore, an engineering of introducing NO 3 into carbonate-based electrolytes by synthesizing targeted covalent organic framework (EB-COF:NO 3 ) to modify Li anode for incubating a reliable SEI is reported. Its unique structure not only facilitates the desolvation process of lithium ions (Li + ) to accelerate the transport of Li + , but also releases NO 3 to form beneficial Li 3 N, LiN x O y species to in situ construct a stable SEI. With the application of EB-COF:NO 3 , the cycling and rate performance of (50 µm) Li//LiFePO 4 full cell is comprehensively improved under the conditions of poor electrolyte and high loading, significantly increasing capacity retention from 14% to 94% after 200 cycles. And the high voltage Li//LiNi 0.5 Mn 1.5 O 4 full cell still demonstrates excellent cycling stability with the capacity retention of 92% after 600 cycles. Accordingly, this strategy shares a prospect for the application of covalent organic frameworks (COFs) to build a stable SEI for high-energy-density LMBs, and also broadens the application of LiNO 3 in carbonate-based electrolytes.

the cycling of the Li metal anode, it is difficult for the conventional electrolyte to form stable and homogeneous solid electrolyte interphase (SEI) layer on the electrode to protect the interface, and the consequent incomplete SEI will further induce the growth of Li dendrites and finally cause cell failure. [7,8] Poor recyclability and serious safety problems have greatly hindered the commercialization of LMBs.So far, tremendous efforts have been invested to inhibit the growth of Li dendrites and boost the Coulombic efficiency (CE) of LMB, multiple methods such as constructing artificial SEI, [9] using 3D porous current collectors, [10] modifying separators, [11,12] optimizing electrolyte composition and forming Li-based alloys have been adopted. [13][14][15] From the perspective of commercialization potential, electrochemical performance, and environmental protection, adding the appropriate amount of additives to commercial carbonate electrolytes is undoubtedly the most advantageous way to optimize the performance of LMBs. [16] To date, additives like some sulfur-containing compounds, [17] inorganic salts, [18][19][20] and fluorine-containing materials [21,22] have been found with high Li-metal compatibility and proved effective in forming stable SEI layer. Nevertheless, most additives will preferentially participate in the interfacial reactions that cause their concentration to drop, leading to the gradual failure of the additives during cycling. [23] It should be noted that increasing the dosage of additives will not only raise the cost, but also accelerate the unfavored side reactions due to the increased concentration of unstable active groups (such as -F, -S(O) 2 -, etc.) and higher viscosity, leading to electrolyte deterioration and gas production (Figure 1a). [24,25] To conquer the above issues, several LiNO 3containing additives have been successfully developed recently inspired by the sustained-release strategy, and their impressive performances demonstrate the great application potential of this method. [26,27] Therefore, optimizing the overall performance and cost of additives designed based on this strategy is of great research significance.Herein, we adopt cheap, environment-friendly CaCO 3 nanoparticles (40-80 nm) as a novel solid additive for LMBs.

“…[26] Jin et al designed a nitrogenrich SEI-coated SLMP by the direct addition of LiNO 3 into the slurry mixing, which created a homogeneous surface over the commercial lithium metal powder (Figure 2b). [27] Liu and co-workers reported a nanoscaled ionic liquid-coated SLMP (<500 nm). The coating of ionic liquid (tetrabutyl-phosphonium bis(trifluoromethyl sulfonyl)imide) prevented the Li metal powder from agglomeration and contributed to an even prelithiation of Si, SiO, and SnO 2 anodes.…”

The ever‐growing market of portable electronics and electric vehicles has spurred extensive research for advanced lithium‐ion batteries (LIBs) with high energy density. High‐capacity alloy‐ and conversion‐type anodes are explored to replace the conventional graphite anode. However, one common issue plaguing these anodes is the large initial capacity loss caused by the solid electrolyte interface formation and other irreversible parasitic reactions, which decrease the total energy density and prevent further market integration. Prelithiation becomes indispensable to compensate for the initial capacity loss, enhance the full cell cycling performance, and bridge the gap between laboratory studies and the practical requirements of advanced LIBs. This review summarizes the various emerging anode and cathode prelithiation techniques, the key barriers, and the corresponding strategies for manufacturing‐compatible and scalable prelithiation. Furthermore, prelithiation as the primary Li+ donor enables the safe assembly of new‐configured “beyond LIBs” (e.g., Li‐ion/S and Li‐ion/O2 batteries) and high power‐density Li‐ion capacitors (LICs). The related progress is also summarized. Finally, perspectives are suggested on the future trend of prelithiation techniques to propel the commercialization of advanced LIBs/LICs.
