Diabetic foot is a common and severe chronic diabetic complication and has become a public health issue, 1 with the global prevalence of diabetic foot ulcer (DFU) being 6.3%. 2 Around 25% of patients with diabetes develop a foot ulcer in their lifetime, 3 and compared to nondiabetic patients, those with DFU have higher amputation rates and increased mortality. 4 Peripheral arterial disease, diabetic peripheral neuropathy, deformity, previous amputation, and infection are the main factors contributing to the development of DFU. 5 Hence, early identification of risk factors for the diabetic foot is especially important for its prevention and treatment.

Considered the promising anode material for next‐generation high‐energy lithium‐ion batteries, SiOx has been slow to commercialize due to its low initial Coulombic efficiency (ICE) and unstable solid electrolyte interface (SEI) layer, which leads to reduced full‐cell energy density, short cycling lives, and poor rate performance. Herein, a novel strategy is proposed to in situ construct an artificial hybrid SEI layer consisting of LiF and Li3Sb on a prelithiated SiOx anode via spontaneous chemical reaction with SbF3. In addition to the increasing ICE (94.5%), the preformed artificial SEI layer with long‐term cycle stability and enhanced Li+ transport capability enables a remarkable improvement in capacity retention and rate capability for modified SiOx. Furthermore, the full cell using Li(Ni0.8Co0.1Mn0.1)O2 and a pre‐treated anode exhibits high ICE (86.0%) and capacity retention (86.6%) after 100 cycles at 0.5 C. This study provides a fresh insight into how to obtain stable interface on a prelithiated SiOx anode for high energy and long lifespan lithium‐ion batteries.

A novel and facile strategy for fabricating red phosphorus@nitrogen doped graphene/carbon nanotube aerogel (P@NGCA) is proposed as free-standing anode for high energy sodium-ion batteries. Owing to an optimized structure of...
