Summary: In this study, wood-derived hierarchical porous free-standing carbon framework materials were used as three-dimensional conductive current collectors to assemble high-performance lithium-sulfur batteries. The micron-scale pores of wood promote electrolyte diffusion, while the introduction of nanopores on the carbon skeleton inhibits the dissolution and shuttle effect of lithium polysulfide, enhancing the rate and cycle performance of the batteries. The porous carbon framework, with adjustable density, allows for a specific capacity of 1120 mAh/g and good rate performance. After 500 cycles, the capacity decay is only 0.11%/cycle and 0.08%/cycle at 0.5 C and 1 C, respectively. Additionally, wood is a cost-effective and renewable material, and the batteries can be assembled without conventional conductive agents, binders, and current collectors.

Summary: The energy and power density of LiNi0.5Co0.2Mn0.3O2 (NCM523) can be improved by enhancing the upper -limit voltage and the charging/discharging rate respectively, but they also lead to severe capacity decay. While the high-voltage capacity fading mechanism of NCM523 has been widely studied, the one affected by the charging/discharging rate remains unclear. This work reveals the long-cycle capacity degradation mechanism of NCM523 caused by rate-dependent kinetic limitations, which can contribute to the design and improvement of high-energy/power-density lithium-ion batteries.
