Article Synopsis
- * Researchers developed carbon/silicon composites using gelatin and sodium alginate, employing techniques like liquid-phase preparation and freeze-drying, resulting in a stable structure with N-doped carbon.
- * The new Si@C composite demonstrated impressive cycling stability with a reversible capacity of 580 mA h g after 300 cycles and excellent rate performance at various current densities, suggesting it could be a viable alternative for battery anodes.
The all-solid-state lithium battery (ASSLIB) is one of the key points of future lithium battery technology development. Because solid-state electrolytes (SSEs) have higher safety performance than liquid electrolytes, and they can promote the application of Li-metal anodes to endow batteries with higher energy density. Glass-ceramic SSEs with excellent ionic conductivity and mechanical strength are one of the main focuses of SSE research.

- The study aims to analyze the HPLC fingerprint of Dipsacus asper root before and after it is processed into wine to observe changes in chemical composition.
- HPLC analysis was conducted using a specific column and gradient elution setup, revealing significant changes in compound levels, particularly an increase in asperosaponin VI and the appearance of two new peaks.
- The findings suggest that this HPLC method is effective for assessing the differences in chemical composition between raw and wine-processed Dipsacus asper root, aiding in quality control.
