“…Many macropores maintain their initial shapes and sizes after cycling at such a high current density, which is favourable for obtaining good cycling stability. [27,28,38,[44][45][46]53,[60][61][62] compares the electrochemical performance of the current study with the previously reported works. It can be seen that the electrochemical performance of the HPC anode is superior to most of reported biomass-based carbon materials.…”

As lithium-ion battery (LIB) anode materials, porous carbons with high specific surface area are highly required because they can well accommodate huge volume expansion/contraction during cycling. In this work, hierarchically porous carbon (HPC) with high specific surface area (~1714.83 m2 g−1) is synthesized from biomass reed flowers. The material presents good cycling stability as an LIB anode, delivering an excellent reversible capacity of 581.2 mAh g−1 after cycling for 100 cycles at a current density of 100 mA g−1, and still remains a reversible capacity of 298.5 mAh g−1 after cycling for 1000 cycles even at 1000 mA g−1. The good electrochemical performance can be ascribed to the high specific surface area of the HPC network, which provides rich and fast paths for electron and ion transfer and provides large contact area and mutual interactions between the electrolyte and active materials. The work proposes a new route for the preparation of low cost carbon-based anodes and may promote the development of other porous carbon materials derived from various biomass carbon sources.

“…6 The difference causes some stumbling blocks in the application of SIBs such as Na-C compounds cannot be formed to store Na + in graphite which is the commercially used anode material in LIBs. 7 Hard carbon, which has presented good electrochemical performances in alkali metal batteries, 8,9 is considered to be the most promising anode material for SIBs due to the high reversible capacity, low sodium storage potential, and excellent cycling stability. 10 Sodium storage mechanism in hard carbon is still not thoroughly understood.…”

“…The I D /I G ratio of the P‐CFs (1.02) is higher than that of the CFs (0.98), indicating higher disordered structure and more surface defects for P‐CFs. [ 28,29 ] The N 2 adsorption isotherms of the samples were calculated using the BET and BJH methods; the results are shown in Figure 2C. The N 2 adsorption isotherms of the P‐CFs show obvious hysteresis loops and characteristic type IV features.…”

Nitrogen‐doped porous biomass carbon with ultrastable performance as anodes for potassium‐ion batteries

The potential safety hazards and limited lithium resources of lithium‐ion batteries (LIBs) have restricted their practical application. Potassium‐ion batteries (KIBs) are a novel energy storage technology with great cost advantages and are a promising alternative to LIBs. However, because of the large ionic radius of K+, the common anode materials used in LIBs exhibit a large volumetric expansion and structural collapse in the process of charging and discharging in a KIB. In this work, the prepared nitrogen‐doped porous carbon fibers (P‐CFs) from bombyx mori silk cocoons via a simple KCl activation and high‐temperature carbonization method. The P‐CFs possess a large specific surface area and one‐dimensional porous structure, offering facile storage and fast transport channels for K+ ions. When used as an anode for KIBs, the P‐CFs exhibit a high reversible specific capacity of 275 mAh·g−1 at a current density of 0.1 A·g−1 after 500 cycles and even retain a capacity of 100 mAh·g−1 after 5000 cycles at 2 A·g−1. This study demonstrates a simple strategy for the low‐cost synthesis of nitrogen‐doped porous carbon fibers from an environmental friendly biomaterial, with excellent electrochemical performance as an anode for KIBs.
