Summary: As an alternative to water oxidization, urea oxidization reaction (UOR) shows promise due to its favorable thermodynamics. However, the inefficiency and impracticality of UOR by Ni-based catalysts is caused by the reliance on the proper Ni oxidization state and passivation at high potentials. This study investigates the anodic characteristics of NiFe-layered double hydroxide (NiFe-LDH) catalyst in a urea-containing alkaline electrolyte and proposes plasma processing for enhanced UOR activity and passivation avoidance.

Summary: This study reports micro-sized porous bulk bismuth particles caged by carbon (P-Bi/C) with micro-and nanoscale elements as anodes for sodium-ion batteries. Bicontinuous nanopores provide buffer spaces to accommodate volume expansion of bismuth during cycling, while interconnected bismuth nanoligaments maintain excellent electrochemical stability. Moreover, the reversible formation of NaBi and hexagonal Na3Bi phases with high sodium-ion diffusivity enables fast electron and ion transport. The P-Bi/C anode exhibits a high initial Coulombic efficiency of 95.2%, a high rate capability of 153.2 mAh g-1 at 150C (1C = 400 mA g-1), and excellent cycling stability for over 20,000 cycles. This work aims to advance practical applications for bismuth in fast-charging sodium-ion batteries.
