    Abstract Transition metal oxides, fluorides, and sulfides are extensively studied as candidate electrode materials for lithium-ion batteries driven by the urgency of developing next-generation higher energy density lithium batteries. These conversion-type electrode materials often require nanosized active materials to enable a "smooth" lithiation and de-lithiation process during charge/discharge cycles, determined by their size, structure, and phase. Herein, the structural and chemical changes of Copper Disulfide (CuS

    Abstract Herein, we demonstrated how the processing routes of OD-Cu affected the surface structure and electrochemical reduction of CO₂. We found that the OD-Cu obtained by H₂ annealing is large Cu nanoparticles (>100 nm) while the OD-Cu processed by electrochemical reduction possesses a porous structure of aggregated small Cu + Cu₂O nanoparticles (∼5 nm). These structural differences lead to a distinct performance.

    Abstract Here, a poly(vinylidene fluoride) (PVDF)-based composite polymer electrolyte (CPE) with a unique Li₀.₃₃La₀.₅₆TiO₃ (LLTO) nanotube filler, which shows a high Li-ion conductivity, is reported. Compared with LLTO nanoparticles (NPs) and nanowires (NWs), the LLTO nanotube fillers increase the interfacial area between PVDF and the LLTO filler, leading to the simple transportation of Li-ions through these interfacial pathways. In addition, the Li plating and stripping cycling performance of the CPEs is improved to 205 h at 0.1 mA cm⁻², and the performance of the Li|CPEs|LiFePO₄ cells also achieves a discharge capacity of 120 mA h g⁻¹ after 100 cycles at 0.5C at room temperature. These results demonstrate an effective interfacial strategy for the design of high Li-ion conduction CPEs for all solid-state batteries.

    Abstract Lithium lanthanum zirconium oxide (LLZO) has long been considered as a promising solid electrolyte for all-solid-state lithium (Li) metal batteries because of its interfacial stability when coupled with a Li metal anode. However, the cubic phase of LLZO (c-LLZO) with a higher Li-ion conductivity has a complex atomic structure and is subject to complicated phase transition during its processing and working conditions, which remain largely elusive. Here, we reveal the phase transition process during the formation of c-LLZO nanotubes through detailed microscopic characterization by scanning and transmission electron microscopy as well as X-ray diffraction. We find four typical stages during the formation of c-LLZO along with several intermediate phases including lanthanum (La)-rich cubic lanthanum zirconium oxide (La-rich c-LZO), c-LZO, and La-rich c-LLZO. We also reveal the role of m-Li₂CO₃ and h-Li₂O₂ as the “phase mediator”.

    Abstract Next-generation high-performance lithium-ion batteries (LIBs) with high energy and power density, long cycle life and uncompromising safety standards require new electrode materials beyond conventional intercalation compounds. However, these materials face a tradeoff between the high capacity and stable cycling because more Li stored in the materials also brings instability to the electrode. Stress-resilient electrode materials are the solution to balance this issue, where the decoupling of strong chemomechanical effects on battery cycling is a prerequisite. This review covers the (de)lithiation behaviors of the alloy and conversion-type anodes and their stress mitigation strategies. We highlight the reaction and degradation mechanisms down to the atomic scale revealed by in situ methods. We also discuss the implications of these mechanistic studies and comment on the effectiveness of the electrode structural and chemical designs that could potentially enable the commercialization of the next generation LIBs based on high-capacity anodes.
