Abstract Compensating the irreversible loss of limited active lithium (Li) is essentially important for improving energy‐density and cycle‐life practical Li‐ion battery full‐cell, especially after employing high‐capacity but low initial coulombic efficiency anode candidates. Introducing prelithiation agent can provide additional Li source such compensation. Herein, we precisely implant trace Co (extracted from transition metal oxide) into site 2 O, obtaining (Li 0.66 0.11 □ 0.23 ) O (CLO) cathode agent. The synergistic formation vacancies Co‐derived catalysis efficiently enhance inherent conductivity weaken Li−O interaction which facilitates its anionic oxidation to peroxo/superoxo species gaseous , achieving 1642.7 mAh/g ~Li2O capacity (≈980 agent). Coupled 6.5 wt % CLO‐based with LiCoO cathode, substantial stored within CLO released compensate consumption on SiO/C anode, 270 Wh/kg pouch‐type full‐cell 92 retention 1000 cycles.

Abstract Li‐rich NMCs layered oxides, with the general formula of Li[Li x Ni y Mn z Co 1− − ]O 2 , are known for their exceptionally high capacities but remain yet to be practicalized in real world. They have attracted enormous research attention due complex structure and intriguing redox mechanisms, a particular focus on anionic over past decade. While fundamental understandings fruitful, practical considerations emphasized here by providing perspectives how limited roadblocks guidelines cope these limitations. It is also demonstrated that, via techno‐economic analysis, material cost ($/kg) highly dependent lithium price, still preserve dominance lower pack ($/kWh) than other cathode candidates principally owing larger energy densities. In addition pure application electric‐vehicle batteries, using them as “electrode additive” or “sacrificial agent” can further multiply practicalities assortment scenarios, which discussed.

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

The Ag-C composite anodes facilitate stable LixAg deposition in solid-state batteries. However, the role of carbon and kinetics lithium migration structure remain unclear. Few studies have focused on this critical research area owing to a shortage effective, non-destructive characterization methods that can directly observe Li alloy process batteries real time. In study, formation anode is investigated through operando X-ray diffraction (XRD) analysis scanning electron microscopy combined with situ probing. This enables observation composition morphology as it evolves within during discharge. Further insights from transmission microscopy-electron energy loss spectroscopy first-principles simulations lithiophilicity barrier for reveal complex mechanism anode.
