Pre-lithiation strategy to design a high-performance zinc oxide anode for lithium-ion batteries

“…2i, the as-prepared Li-ZnO shows a distinct EPR signal at g = 1.957, and the EPR signal is not distinguishable in the pristine ZnO. 37 According to the previous study, the distinct EPR signal in the as-prepared Li-ZnO is ascribed to the spin resonance of the introduced free electrons via this pre-lithiation treatment. 38 These analyses further reveal the construction of a pre-lithiated Li-ZnO nanorod anode with enhanced electronic conductivity, charge transport kinetics and electrochemical properties after the high-temperature solid-state reaction under an argon atmosphere.…”

Influence Mechanism of Interfacial Oxidation of Li3YCl6 Solid Electrolyte on Reduction Potential

“…Inorganic SEs including oxides, sulfides, and borohydrides have been vastly investigated in recent years, while challenges of performance elevation and scaled manufacturing remain for practical applications [3–5] . Oxide SEs such as garnet (LLTO), [6] NASICON (like LATP) [7] or spinel‐typed lithium conductors [8] exhibit high chemical and physical stability, with good compatibility with cathode materials and high mechanical strength, but these materials face the limitation of low ionic conductivity and high interfacial resistance [9–11] . Sulfides possess high ionic conductivities comparable to traditional liquid organic electrolytes, but a narrow electrochemical window and poor stability with electrodes, together with potential evolution of hazard S‐containing gases, severely limit their application [12–14] .…”

Revisiting the Temperature-Dependent Phase Structure of Spinel LiNi0.5Mn1.5O4 for Lithium-Ion Batteries

“…Lithium-ion batteries (LIBs), first introduced by Yoshino in 1985, have become integral to our daily lives due to their significant technological impact and widespread use. The growing demand for affordable and high-energy-density LIBs is driven by their essential role in powering portable electronic devices, as well as electric and hybrid electric vehicles. − At present, widely used materials such as LiCoO 2 (layered structure and easy collapse of the crystal lattice) and LiFePO 4 (orthogonal olivine structure, low vibration density, and poor conductivity) are limited by their respective shortcomings. , Spinel LiNi 0.5 Mn 1.5 O 4 (LNMO) demonstrates remarkable potential as a prospective material for future high-energy-density batteries. This potential arises from its favorable attributes, encompassing an elevated operational voltage of 4.7 V vs Li/Li + , an impressive energy density of 650 Wh kg –1 , and its cost-efficient nature. − Generally, LNMO is divided into disordered ( Fd 3̅ m phase) and ordered ( P 4 3 32 phase) structures due to the different transition-metal (TM) distribution arrangements. − As shown in Figure , the structure of LNMO is derived from a cubic-close-packed configuration of O atoms, with the TMs occupying 50% of the octahedral sites.…”
