Potassium ion batteries (PIBs) are a viable alternative to lithium-ion batteries for energy storage. Red phosphorus (RP) has attracted a great deal of interest as an anode for PIBs owing to its cheapness, ideal electrode potential, and high theoretical specific capacity. However, the direct preparation of phosphorus-carbon composites usually results in exposure of the RP to the exterior of the carbon layer, which can lead to the deactivation of the active material and the production of "dead phosphorus".

- - Sodium-ion batteries (SIBs) are being explored for large-scale energy storage due to the low cost and abundance of sodium, but improving their energy density and cycling stability is still a challenge.
- - Researchers synthesized F-doped NaAlV(PO)(NAVP) microspheres and found that the doping enhances sodium diffusion channels, resulting in an impressive capacity of 148 mAh/g at 100 mA/g and 90.8% retention after 200 cycles.
- - The F-doping process improves structural stability and rate performance, with NAVPF showing a discharge capacity of 83.6 mAh/g at a high current rate of 5000 mA/g, making it a promising candidate for future
Solid-state batteries based on lithium metal anodes are expected to meet safety challenges while maintaining a high energy density. One major challenge lies in the fast interface degradation between the electrolyte and the lithium metal. Herein, we propose a quasi-3D interphase on a garnet solid-state electrolyte (SSE) by introducing lithiophilic nanotrenches.

Methods: Multicenter, historical cohort study and superiority test were used. From July 2020 to October 2022, patients with wasp sting injury and multiple organ damage admitted to the intensive care units (ICU) of five hospitals were consecutively screened and recruited into the CVVH+DPMA+HP group (intervention group).
