Summary: Graphitic carbon-based anodes for lithium-ion batteries have shown significant progress and commercial acceptance in the past three decades. However, their performance is limited by low surface area, layer stacking, poor porosity, and low conductivity. To address these limitations, a highly porous three-dimensional graphitic carbon material is developed by using polystyrene as a core and small-sized zeolitic imidazolate framework-67 (ZIF-67) particles as decorators. The material's anodic performance is optimized by adjusting the carbonization temperature, with the samples carbonized at 700°C exhibiting higher performance and stability compared to those treated at 600°C, 800°C, and 900°C. The developed material demonstrates excellent cyclic stability and high discharge capacity, making it a promising candidate for lithium-ion batteries.

Summary: Li-rich layered oxides have the potential to be high-energy-density cathodes for lithium-ion batteries, but their ultimate energy density is still uncertain due to a lack of comprehensive understanding of the first-cycle irreversible capacity. This study reports a non-monotonic irreversible capacity behavior governed by the delithiation depth in Li-rich chemistry, Li1.2Ni0.13Co0.13Mn0.54O2. Contrary to previous beliefs, the irreversible capacity reaches a maximum when the delithiation depth corresponds to x = 0.4 in LixNi0.13Co0.13Mn0.54O2. The non-monotonic irreversible capacity is fully recoverable and strongly correlates with the discharge capacity during deep discharge. Operando synchrotron X-ray diffraction reveals a metastable phase transition to an overlithiated Li2MO2 1T structure during deep discharge, and scanning transmission X-ray microscopy combined with X-ray absorption spectroscopy confirms unrecoverable oxygen release triggered at x < 0.2 in LixNi0.13Co0.13Mn0.54O2. These results provide important insights and guidance for improving the energy efficiency of Li-rich layered cathodes.
