解读硬碳负极低压平台：从储钠模型到活性位点定量设计
Decoding the Low‐Voltage Plateau in Hard Carbon Negative Electrodes: From Sodium‐Storage Models to Quantitative Active‐Site Design
模型导读
一篇综述重新审视硬碳负极的位点分辨储钠机制，指出斜坡容量与平台容量的早期归属（吸附、嵌入或孔填充）往往依赖样品，可能过度解读单一表征信号。文章聚焦低压平台，讨论单层Na积累、准金属Na团簇、闭孔填充及剩余孔体积悖论，并评估WAXS/XRD、SAXS、XPS、Raman、NMR、滴定与理论模拟在判定储钠状态上的优劣。
