Summary: This study designed a localized high-concentration electrolyte (D-LHCE-F) containing dual-salt (LiFSI-LiPF6) and fluoroethylene carbonate (FEC) to improve the interfacial stability of silicon-based electrodes. The addition of FEC and the stable LiFSI salt promoted the formation of a protective SEI layer and increased the flexibility of the interface, enabling the electrode to adapt to volume changes. The SiOx/C electrode using this electrolyte retained 78.5% of its initial capacity after 500 cycles at 0.5C, surpassing the control electrolyte's capacity retention of 3.4%.

Summary: This study reports the automatic self-healing capability of silicon nanowires, which are important building blocks for high-performance semiconductor nanodevices. Through in situ transmission electron microscopy tensile tests, a recovery of fracture strength (10.1%) on fractured silicon nanowires is achieved. Atomic-resolution characterizations and atomistic simulations reveal the self-healing mechanism and factors affecting the self-healing efficiency. Spontaneous rebonding, atomic rearrangement, and van der Waals attraction are responsible for the self-healing in silicon nanowires. The findings shed light on the self-healing mechanism of silicon nanowires and provide insights into developing high-lifetime and high-security semiconductor devices.

Summary: Layered nickel-rich transition metal oxides have advantages of high energy density and reasonable cost, but suffer from volume changes that result in microcracks, fractures, and degradation of thermal stability during charge-discharge cycling. In this study, a codoping strategy of Mg and Ti in Li[Ni0.90Co0.05Mn0.05]O2 (NCM90) was proposed, achieving excellent cyclability (98.9% vs 86.6%) after 100 cycles. The enhanced electrochemical performance and reduced volume changes were confirmed by testing an NCM parallel to graphite full cell. This study provides valuable guidance for the application of high nickel cathodes in lithium-ion batteries with improved cycling and thermal stability.
