Summary: This review provides a comprehensive summary of the important role of pre-lithiation in lithium-ion capacitors (LICs) and the application of cathode sacrificial lithium salts (CSLSs) in pre-lithiation strategies. Various pre-lithiation methods are systematically discussed and compared, highlighting the lithium extraction mechanism of CSLSs and their influence on LICs performance. A summary and outlook are provided to guide the development of new pre-lithiation technologies.

Summary: In contrast to previous findings, a high-temperature phase Li-4.1 Si, rather than the commercial phase Li15Si4, was observed in the hollow-structured silicon anode of a Li-ions battery after lithiation. The formation of Li-4.1 Si, as well as other lithium silicides, could be ascribed to the polymorphic transition theory that promoted the formation of a metastable phase. This kind of phase transition may occur not only in hollow-structured silicon nanoparticles but also in other particles with specific morphologies if the requirements for polymorphic transition are satisfied.

Summary: In this study, four ethers were compared as solvents for lithium naphthalenide (Li-NTL) solutions for pre-doping lithium into silicon electrodes. The results showed that the solvents have an impact on the stability and equilibrium potential of Li-NTL solutions, which in turn affects the doping capacity.

Summary: In-situ chemical pre-lithiation strategy was used to fabricate onion-like SiOC/C spheres with high initial coulombic efficiency. The uniform generation of LixSiOy inside the spheres effectively reduces the irreversible consumption of Li ions and simplifies the pre-lithiation process. The structures of SiOC/C spheres also provide superior structural integrity, showing potential for high energy density and cycling stability in LIB applications.

Summary: Pre-lithiation using cost-efficient electrolytes based on LiCl is successfully demonstrated for enabling lithium-ion battery full-cells with high silicon content negative electrodes. An optimized electrolyte based on gamma-butyrolactone and LiCl, with boron-containing additives and CO2, is shown to form a protective SEI on silicon thin films. This electrolytic pre-lithiation technique improves the capacity retention of NCM111||Si full-cells.

Summary: Lithium/Sodium-ion batteries have attracted attention due to their high energy density and long cycle life. One major challenge is the initial irreversible capacity loss, which can be overcome by pre-lithiation/sodiation. Pre-lithiation/sodiation additives are preferred due to their easy adaptability and compatibility with the current battery manufacturing process. This review consolidates recent developments in using pre-lithiation/sodiation additives to improve the energy density and cycle life of lithium/sodium-ion batteries.

Summary: Graphite is the dominant anode material for lithium-ion batteries, but it is prone to Li-plating when charged fast or at low temperatures, resulting in performance degradation and safety concerns. This study clarifies the mechanism of lithium evolution from graphite particles and reveals that the degradation of graphite anode is accelerated by the decrease of Li-plating overpotential. This finding contradicts the popular theory and provides insight for the design of advanced materials and electrodes to avoid Li-plating and achieve fast and safe charging.
