Metal Battery Anode: Rich in Electrons, Rich in Problems: A Critical Review from Industrial Perspectives

open access: yesAdvanced Science, EarlyView.
Metal‐anode batteries using Li, Na, Mg, and Ca offer exceptionally high energy density, but dendrites, unstable interphases, cracking, and pore formation hinder durability and safety. This review shows how careful electrolyte and interphase design can stabilize these reactive metals.

MgP4/CNT‐Graphene Embedded in Hard Carbon Matrix as a High‐Capacity Anode for Next‐Generation Sodium‐Ion Batteries

open access: yesAdvanced Science, EarlyView.
Phosphorus‐rich MgP4 is introduced as a high capacity anode for sodium‐ion batteries (SIBs) via hybrid carbon matrix engineering. A sequential CNT/G assembly forms a conductive and mechanically robust network, delivering a high reversible capacity of 1386 mAh g−1 while stabilizing alloying reactions.
